This manual was written to aid the user in the Installation and Operation of the software SmartConnect™
developed by SmartMove GmbH, for configuring and managing the DC900 and DC2000 boards.
S YS T EM R EQ UI R EM E NT S
SmartConnect can be installed on any standard PC running Windows XP™ or Windows Vista™. The
recommended minimum memory is 512MB RAM and 50MB free hard disk space. To connect a DC900
or DC2000 board with a PC, a serial (RS232) interface or a USB to serial adapter with a serial cable as
defined below is needed. If running SmartConnect to control a remote DC board, a network connection is
necessary and special program supplied with the installation must be run. See Appendix A for details.
If you are running the DC product for the first time and would like to know how to find the best setup for
increased speed in marking, refer to Application Note # A.1.2.1.1.B, Digital State Space Speed

Configuring the DC board for user interaction
The DC900 and DC2000 have a 10-pin header on the digital module that is used to connect the DC board
DSP to a host PC via an RS-232 connection. Even though only TXD, RXD and GND are required for
communications to take place, this header is wired in such a way as to simplify the construction of an adapter
cable by means of mass-terminated IDC style connectors. Figure 37 illustrates an adapter cable that is
suitable for plugging into a standard 9-pin male D-type COM port connector used on most commercial PC
systems. Table 5 defines the signals that are actually used by the DC2000 and DC900. An RS-232 cable to
connect the DC2000 or DC900 with a serial port is available, CTI part number 6017-1, available in 24” and 72”
lengths.

The SmartConnect GUI is made-up of different elements. On the top is the menu bar (1) with selections for
File, Connection, Board, Watchlist and Help. Below the menu bar is the Button bar (2). To the right of the
Button bar is the Board-Connection Status (3) window. The center of the window is split into two vertical parts
with the left side (4) containing the Watchlist information and the right side (5) containing the ParameterFile
data, Test Plots, Scope1, Scope2 and XYPlot (DC900 does not use Scope2 & XYPlot, see Figure 3). The
lower part of the GUI (6) is reserved for hosting the Board Message, SmartConnect log and terminal data
windows. The size of the windows can be changed by left clicking and dragging their borders.
The Board-Connection Status window (3) will change color depending on the boards status:
1. Blue means no connection
2. Green means connected
3. Red means connected, but board is busy

There are two ways to connect to the DC board. The simplest method is the direct connection, which is done
via a serial (RS232) cable. See Appendix B: PC to DC Board Connection for a definition of the serial cable.
The other way is to establish a connection through the internet, which will be discussed in Appendix C:
Com2tcp, for now we will use a local serial connection. Click on the Connection tab to start the connection to
the DC board (see Figure 5). Select Connect via serial and in the Serial window enter the number of the serial
port connected to the DC board (see Figure 6) then click OK.
Note: Be sure that you have inserted the J1 jumper (as shown on page 25) on the DC board if you plan to
make any changes to the board settings.

The board-connection status has gone to green color, signaling the board is ready to accept commands. On
the left side the Watchlist has been refreshed and on the right side plots for the resonant frequencies and
friction were read from the board. Also the bottom status bar has been updated. If you click on the
ParameterFile tab in the right window you will see the Parameters that are stored on the board.

In the menu Board files can be uploaded to the DC board. There are two different kind of files to use.
First, there are firmware (FW) files, which are used for updating the board operating software by
selecting the menu entry Send FW to Board. As second class of files, normal files (like data files) can be
sent by choosing the menu entry Send file to Board. Once you select either one of these a browser
window will open so that you can select the appropriate file to load to the board.
Figure 23 Board Menu
For all files selected for uploading to the board, a progress indicator in the status bar will show you when
the upload is complete. After the upload is complete, SmartConnect will refresh the board states.
Figure 24 Status Bar
Note: If you can not connect to the board through SmartConnect, SmartConnect will not be able to automatically start the
file transfer process. In this case, after you tell SmartConnect to send the file, you will need to power cycle your DC board,
turning it off, then on. This will bring it to the proper point in the boot cycle to send any files.

In the Watchlist menu (in the menu bar) with the entry “Update ParaFile” all ‘touched’
(changed in red) variables, which are members of the parameter file, are written to the parameter
file. The “Update Board” selection will then write all the touched variables to the DC board.

The Button Bar is made up of six (6) buttons, broken into three (3) groups that are allocated to specific
commands in SmartConnect.
Group1 Buttons
Group1 is made up of two buttons, 1) Refresh button will update all the data in the Watchlist and
ParameterFile/Plots windows with the current data from the DC board. 2) Continue button will allow the
software to move to the next stop point in the software, such as Post Init the initial stop point to Post Test
stop point.
Figure 27 Group1 Buttons
Group2 Buttons
Group2 is made up of three buttons, 1) CleanUp button will clear out all data in the DC board ram disk
including the test results and will restart the DC firmware. The DC board will then stop at Post Init. Since
all RAM data was erased, from Post Init on the board will behave the same as if the DC board had been
powered down. 2) SW-Reset will restart the firmware and take the DC board back to Post Init. Since all
test data will stay in RAM, the attached scanner(s) will not be retested. 3) HW-Reset button will do a full
reset of the DC board and stop at Post Init. The attached scanner(s) will not be retested, because the DC
board RAM disk will be untouched by a hardware reset.

The Watchlist information part of the GUI allows the user to view board internal variables (data
structures). This interface is necessary for monitoring and managing the DC board firmware. Due to the
high number of board internal states, the Watchlist comes with the feature for organizing variables in
different tabs for building up groups.

The Watchlist columns are:

W: writeable but not used in the parameter file
P: member of the parameter file
(If enable) the low border of the value
(If enable) the high border of the value
Description A short description of the variables content
The value of a Watchlist variable is a local (Host PC) copy of the DC board values. This means, the data
shown in the Watchlist can be different than the data on the board. But this depends on the configuration
used, some configurations support an ‘auto-update’ feature to avoid displaying outdated values. For
synchronizing the values, the data can be read from the board using the Refresh button or any of the Get
functions from the Right Mouse Button menu and written to the board using the “Send value” function
from the Right Mouse Button menu. If the user changes a value (Flags must be O or P), it gets marked
red (‘touched’) and is sent to the board immediately. A value can also be forced to be sent to the board

(see Watchlist RMB-Menu).
Be aware that any variable written to the DC board could be removed by a reset or power down of the board
unless it is written to the Parameter file and the Parameter file is saved to the board. It would be advisable for
the user to also save to file, a copy of the modified Parameter file as a backup for any changes.

The Parameter file (PF) is a file stored on the DC board, which is read at the board startup. The
Parameter file lists variables and their values that will override the board firmware’s intrinsic values. This
mechanism allows for the behavior of a DC board to be permanently changed without changing the
firmware, which reduces the number of firmware versions required.

Plots are graphical visualizations of data-sets read from the board. They can be displayed in
tabs located in the right part of SmartConnect. The data-set within a plot is represented by a graph. A
plot can contain several graphs. A plot-tab can contain up to 4 plots. A plot will always have a name and
two axis (X and Y) with each axis having a unit. With a single left mouse click, the coordinates pointed to
are reflected in the left most portion of the status bar.

To Zoom in on a certain part of a plot, all you need to do is hold down the left mouse button while you
draw a box around the area of interest and when you release the left mouse button the selected are will
be displayed. To Unzoom the selected area, just hold your mouse over the plot, click the right mouse
button and select Unzoom from the menu. One plot in a tab can be selected to serve as X-Zoom Track,
this means that zooming in on the plot that has X-Zoom checked will also zoom in on all other plots (in
terms of X-axis) in this tab. This feature is useful to take a closer look at a certain region, if all plots are
sharing the same X-axis domain (like time).

Com2tcp is needed to connect to a DC board on a remote location via the internet.
The standard way to connect to the DC board is a serial connection from the PC
running SmartConnect, as shown in the figure below.

The GUI of com2tcp is very simple and requires only a small amount of data. If com2tcp is operated in
server mode (Server box is checked), then SmartConnect has to connect as client. In this mode only the
communication Port: number and the Com Port: where the DC board is connected must be given. After
this, the Start button can be pressed to enable com2tcp listening for incoming connections. As soon as a
remote SmartConnect connects to com2tcp a message is printed in the com2tcp’s log window. If com2tcp
should run in client mode (Server box not clicked), then SmartConnect has to connect as server.
Running com2tcp in client mode requires entering the Host: IP-address (or web address) of the remote
host where SmartConnect is running along with the information for the Port and Com Port.

This value is the maximum angle range that the galvo will scan to in
mechanical half angle degrees. This can be set to prevent the mirrors
from traveling too far by placing a value for this in the Parameter file.
This value is derived from readings taken when the galvo first starts up.
It takes all galvo’s connected to the board and finds their maximum
positive and negative move they can do, by driving them to the
bumper. It then takes the smallest absolute value of those numbers
and subtracts a half degree to use as INPUT_CLIP if it is set to zero. If
INPUT_CLIP is not set to zero then it compares that value with the
value entered in INPUT_CLIP and uses the lesser value. The values
used to determine this can be found in the Test Pos and Neg bumper
positions found in the test tab. This is often helpful in diagnostics if the
movement of the Mirror is being inhibited.
This determines what input mode will be used for moving the galvo’s.
If the Jumper is in and SmartConnect is being used, you can reset the
input mode by simply going to post loop, and then change the value
and returning to closed loop. This allows you to use the on board wave
generator as a diagnostic tool. The wave generator uses all the same
filters except input scale. The amplitude in that case is set by the wave
generator.
This allows you to change the 0,0 point of the system. This can be
th
moved in very small increments down to 1 CentiCount, which is 1/100
of a count being sent to the board.
This sets the scaling between the input command counts and the
output angle. This will have no bearing on the resolution of the system.
Take the number of degrees desired and divide it by the max system
field size, making sure the units of both numbers are the same.
Multiply by 100 to set this number as a percentage. Typically the max
system field size is 60 deg optical range, see SYS_PDRANGE for
other possibilities. This is the “%(15)” unit value for input scale, not the
“%” that the system uses. Right click the units and you can change to
this unit. Because the system needs the “%”unit, that is the value that
will be seen in the parameter file.
For the System PLL to lock with the input command the Digital
command input must be within 1% of 10us (or a multiple thereof) and

or every 2 or 4 data point depending on the update rate.
If this is not feasible for your application then set this parameter to zero
and it will not lock to input command. This will allow for intermittent
skipped data points. For the SC500 this must be zero.
This parameter sets the amount of time allowed to the Optimizing filter
to check and modify the waveform for drivability. This allows the
system to see into the future by putting the entire input command line
into a buffer to be monitored. The board will go through several cycles
evaluating the amount of voltage it has and the desired move to be
done to keep the signal drivable. The ideal setting for this parameter is
the same amount of time as the biggest move your mark will make.
This is usually during a jump so changing the path is not noticeable.
If you are using all structured moves, including jumps, you may not
need this feature and it can be shut off by using zero. Many times in
these cases even a small number is helpful of 5 – 10.
Changing this number does change the overall pipeline delay of the
system as it directly changes the buffer length. For exact delay time
see PRE_DELAY.
This tells you the exact length of the delay in samples. This will include
all portions of the prefilter. In order to have the exact time in
microseconds, multiply this number by SYS_TS.

Rmean is a simple averaging technique that helps

position transitions. It takes a small portion of the
current input position slope and averages it with
the beginning of the next change in command
slope it sees. Then it adds in a little more of the next slope and
averages it in and continues running the average until the next slope
change and then it repeats. The value set in the parameter is the
amount of the previous slope to be used in each running average. This
tends to affect more after the slope change than it will before the slope
change.

of the window to be averaged. The bigger the

not update. When the servo first goes into closed loop it runs a routine
reads the parameter settings and sets up the algorithm to apply to the
Input command. Any subsequent entries into the closed loop process
does not allow for this. In normal operation there would be no changes
and you want to start up again as soon as possible, therefore any
parameter changes that affect this algorithm will not be changed. The
input parameters and the wave generator parameters have no bearing
on this algorithm so they can be changed by simply going into post
loop and then entering back into Closed loop. Parameters that deal
with the Optimizing, Heuristic, Pre-filter, or Controller require a
recalculation of this algorithm. These parameters have a prefix of OF_,
HF_, PRE_ and CTRL_ Respectively. When changing these
parameters, which are usually a part of the setup and testing process,
you need to tell the controller to recalculate when it reenters closed
loop. Set this parameter to 1 and it will do the recalculation once then
reset this parameter back to zero after that so that it will not do it again.
Set it to -1 and it will remain -1 and recalculate the algorithm every time
it enters, until the board is reset.

stream. If the board at any point goes high for the temperature bit or
the error exceeds RT_POS_WARN there are bits to this number that
will latch high. If the error or temperature goes back to a normal range
the XY2-100 bit will change back, the RT_STATUS will not. Changes
in either of these bits can be as small as 1 sample and the RS232
would have to poll that parameter right at that moment to get the value.
Therefore this parameter latches high when any value changes and
stays there while the XY2-100 command line stays active with a live
current reading. This is to enable more diagnosis into the product. To
reset this set this parameter to zero.
To read this value take the number it reads back and look at it in

This parameter is only available on 3-4-0 and newer images. The
standard value is 1. This corresponds to a 60 deg optical range that
sets the resolution of the system. All images before 3-4-0 are set to
this same number, making everything backwards compatible. If you
desire improved dither, and can afford a reduced angle range, then you
can change this value to 0. This changes the resolution and reduces
the max angle range 40 deg optical. It will also reduce the dither by
40-50%. If a wider angle range is desired this can also be done by
setting the number to 2. This changes the resolution and increases the
max angle range to 80 deg optical. However this is at the expense of
dither, as the dither will also increase by 80-90%. Usually higher angle
range applications are susceptible to dither so often this works out.
Further refinement of the angle range can be done with
INPUT_SCALE, which will not affect the resolution.

This tells you what power supply voltage needs to be used with the

can be changed but it does not mean that everything will work properly
if you do. The parameter files are setup for each individual level and
optimized there. The lowest usable voltage is 15 and the maximum is
30.
This tells the length of the sample being used in this image. This is a

above 150 means there is extra noise coming in over the analog
signal. This will not create any errors as there is nothing the board can
do about it; it will merely try to make it work.
At startup the board will test the exact position of each bumper by
swinging each galvo completely positive and negative until it hits a
stop. It assumes this position to the bumper position at each point and
records those in these parameters for calculations and diagnostic work.
It will take the smallest of these values and remove some safety
margin from it compare it with INPUT CLIP. If INPUT_CLIP = zero
then this value will be put in place of the zero, Otherwise, the lesser of
these two values becomes the INPUT_CLIP or the maximum angle
that the board will use, anything above it will be clipped. If one of these
numbers is significantly lower than the others look for something
mechanical blocking the mirror.
This is a test of noise coming back from the galvo. Typically this value
is less than 150. If above that first check the cable, often a bad cable
will cause this number to rise. If the cable is ok it signifies either a bad
galvo or a noise source close to the cable. Above 500, the board will
error out.
This is the Resonant Frequency of the respective Axis; any significant
change here would lead to checking the condition of the mirrors and
galvo.
At startup the board tests that with no signal applied the power
amplifier circuit is offset to 0. If either op-amp has failed this will not be
true.

the number of degrees desired and divide it by the max system field
size, making sure the units of both numbers are the same. Multiply by
100 to set this number as a percentage. Typically the max system field
size is 60 deg optical range, see SYS_PDRANGE for other possibilities.
This is the “%(15)” unit value for input scale, not the “%” that the system
uses. Right click the units and you can change to this unit. Because
the system needs the “%”unit, that is the value that will be seen in the
parameter file.

For the System PLL to lock with the input command the Digital
command input must be within 1% of 10us (or a multiple thereof) and
with in .1% of itself. This allows the system to lock to every data point
nd
th
or every 2 or 4 data point depending on the update rate.
If this is not feasible for your application then set this parameter to zero
and it will not lock to input command. This will allow for intermittent
skipped data points. For the SC500 this must be zero.

Rmean is a simple averaging technique that helps
keep the Voltage from spiking during Large
position transitions. It takes a small portion of the
current input position slope and averages it with
the beginning of the next change in command
slope it sees. Then it adds in a little more of the next slope and
averages it in and continues running the average until the next slope
change and then it repeats. The value set in the parameter is the
amount of the previous slope to be used in each running average. This
tends to affect more after the slope change than it will before the slope
change.

Smean is a simple averaging technique that helps
keep the Voltage from spiking during changes in
input command position. It works as a simple
window average, by taking the value before and after
the current value and averaging them together. The
value of the parameter is the size of the window to
be averaged. The bigger the window the more
rounding you will see as in the above figure, where
the colored lines have been adjusted from the input
black line. The affect on the mark can be seen in
the figure below it.

Recalculate controller 1=Once, -1=Repeatedly

This allows you make updates to certain parameters that normally do
not update. When the servo first goes into closed loop it runs a routine
reads the parameter settings and sets up the algorithm to apply to the
Input command. Any subsequent entries into the closed loop process
does not allow for this. In normal operation there would be no changes
and you want to start up again as soon as possible, therefore any
parameter changes that affect this algorithm will not be changed. The
input parameters and the wave generator parameters have no bearing
on this algorithm so they can be changed by simply going into post loop
and then entering back into Closed loop. Parameters that deal with the
Optimizing, Heuristic, Pre-filter, or Controller require a recalculation of
this algorithm. These parameters have a prefix of OF_, HF_, PRE_ and
CTRL_ Respectively. When changing these parameters, which are
usually a part of the setup and testing process, you need to tell the
controller to recalculate when it reenters closed loop. Set this
parameter to 1 and it will do the recalculation once then reset this
parameter back to zero after that so that it will not do it again. Set it to 1 and it will remain -1 and recalculate the algorithm every time it enters,
until the board is reset.

This will change the error bit of the XY2-100 command line status based

greater than this value the status bit will change. This is independent of
board operation and could be set for before or after the board would
shut down. This value can be change in increments as small as 1

This monitors two of the items from the XY2-100 input command
stream. If the board at any point goes high for the temperature bit or the
error exceeds RT_POS_WARN there are bits to this number that will
latch high. IF the error or temperature goes back to a normal range the
XY2-100 bit will change back, the RT_STATUS will not. Changes in
either of these bits can be as small as 1 sample and the RS232 would
have to poll that parameter right at that moment to get the value.
Therefore this parameter latches high when any value changes and
stays there while the XY2-100 command line stays active with a live
current reading. This is to enable more diagnosis into the product. To
reset this set this parameter to zero.
To read this value take the number it reads back and look at it in binary.
Least significant bit is temperature. The second bit is not used in the
DC2000, the third bit is error of X and the fourth is error of Y. A value of
1 is temperature; a value of 5 is error X and temperature.
IR_VOLTAGE1
This allows you test the Offset of the power amplifier as a diagnostic
tool. To use it you need to command a zero level to the board and then
monitor this to see how well it can do that. This can be noted at system
test then compared to what is in the field. The number will be in Counts,
telling you how much offset there is from zero. A reading of 600 counts
would be equivalent to about 1 volt of offset.

Motor position range. 0:+/-10deg, 1:+/-15deg, 2:+/-20deg
This parameter is only available on 3-4-0 and newer images. The
standard value is 1. This corresponds to a 60 deg optical range that
sets the resolution of the system. All images before 3-4-0 are set to this
same number, making everything backwards compatible. If you desire
improved dither, and can afford a reduced angle range, then you can
change this value to 0. This changes the resolution and reduces the
max angle range 40 deg optical. It will also reduce the dither by 4050%. If a wider angle range is desired this can also be done by setting
the number to 2. This changes the resolution and increases the max
angle range to 80 deg optical. However this is at the expense of dither,
as the dither will also increase by 80-90%. Usually higher angle range
applications are susceptible to dither so often this works out. Further
refinement of the angle range can be done with INPUT_SCALE, which
will not affect the resolution.

This tells you what power supply voltage needs to be used with the
board. This is in positive and negative from two supplies, and the
current rating should be matched to the galvo being used. The boards
themselves will not even turn on unless 2 amps is supplied. This value
can be changed but it does not mean that everything will work properly
if you do. The parameter files are setup for each individual level and
optimized there. The usable voltage range is 15 to 30 volts.
This tells the length of the sample being used in this image. This is a
firmware setting in the image and is typically at 20us. Some larger
galvo and mirror combinations require 40us.

At startup the board will test the exact position of each bumper by
swinging each galvo completely positive and negative until it hits a stop.
It assumes this position to the bumper position at each point and
records those in these parameters for calculations and diagnostic work.
It will take the smallest of these values and remove some safety margin
from it compare it with INPUT CLIP. If INPUT_CLIP = zero then this
value will be put in place of the zero, Otherwise, the lesser of these two
values becomes the INPUT_CLIP or the maximum angle that the board
will use, anything above it will be clipped. If one of these numbers is
significantly lower than the others look for something mechanical
blocking the mirror.
This is a test of noise coming back from the galvo. Typically this value
is less than 150. If above that first check the cable, often a bad cable
will cause this number to rise. If the cable is ok it signifies either a bad
galvo or a noise source close to the cable. Above 500 and the board
will error out.
This is the Resonant Frequency of the respective Axis; any significant
change here would lead to checking the condition of the mirrors and
galvo.
