1. Program Installation
Start by running the Vis2020-4.X-win32 file provided and the installation process will begin.
Follow the on screen prompts and once the install is complete, the driver for the optical cable
must be installed. This is located in the Vision 2020 folder under program folder on the hard
drive. If the user does not have .NET Framework installed, the installation will detect this and
automatically install the proper version of .NET Framework. Vision 20/20 can now be started.
During the initial run of the application, it is necessary to select a COM port for the attached
Optical probe. This is accomplished by selecting SETTINGS located on the upper most banner
and then selecting COM settings from the main screen. After the initial selection the program will
save this COM setting for future use.

3. Meter Compatibility With 4.0
Meters containing firmware earlier than 4.0 will not communicate with Vision 20/20 version 4.0.
When trying to read a meter in this instance, a “Firmware not compatible” message box will
appear as shown below in Figure A (see note). Clicking the Ok button will open version 2.7 of
Vision 20/20. Version 2.7 is not covered in this manual.
Figure A
Note: Vision 20/20 version 2.7 will automatically launch only if “Check all Protocols” has been
selected under the Application Settings menu. If this option is not set, then a “Communications
Error” message will display on the status bar.
4. Configuring Meter with Vision 20/20
Meters are configured to customer specifications at the factory. To save time, the Read Meter
button can be utilized to retrieve the meters current settings. The Configuration screen is the first
and main screen. The Read Meter button is located at bottom left on the Configuration screen.
After viewing the current settings, changes can be made and applied to the meter by using the
Program Meter button. This button is located at bottom right of the main screen. In addition,
Vision 20/20 also provides the Configuration screen which provides a multitude of useful data
which can be viewed by pressing the Read Meter button.
Note: The meter must be energized and the optical probe must be used to perform any read or write
functions.

5. Main Screen
5.1 Configuration Screen
The user may find it helpful to configure some of these settings upon first use of Vision 20/20.
The Configuration screen is the main screen upon launching Vision 20/20, Figure 2. The meter
can be read by clicking the Read Meter button located at bottom left. The Reset Meter button
will reset errors, demand settings and registers. The Program Meter button is not accessible in
User mode and therefore nothing can be written to the meter. However, this is how the main
screen appears in Supervisor mode until a meter has been read. Notice first the File, Edit,
Phasor Diagram, Meter Error List, Application Settings and Help selections located on the
upper task bar. The File tab allows the user to open, save as or exit. The Edit tab allows user to
copy, paste or cut. The Phasor Diagram and Meter Error List tabs are not selectable until the
meter has been read. Refer to Section 14 for detailed information on the Phasor Diagram
function.
The Application Settings tab allows the user to select Log Out, COM port, Enable Warnings,
Change password, Radio Not Supported or Check Old Protocol Version. This is shown below in
Figure B. The Security Key selection is only available when the present key won’t provide
access to the meter. This provides the user the opportunity to input a different key, and is detailed
in Section 9. The Help tab allows user to select About or Help. By clicking on the Help tab, the
user may select Shortcut Keys. These are provided to help simplify and expedite routine and
repetitious reading and programing functions. This is shown below in Figure C.

5.2 Enable warnings
Vision 20/20 4.X contains a number of pre-defined warnings which can be displayed. Located in
the Application Settings tab of the upper task bar as shown above in Figure B, the user simply
selects which warning(s) are important. To select or unselect any individual warning message,
simply click to add or remove the checkmark.
5.3 Protocol Version
Also located in the Settings tab shown above, is the Check Old Protocol Version option. If
selected, Vision 20/20 4.X will check the meter’s firmware first when reading a meter. If the user
is confident that the meters they will read/program contain firmware of version 4.X or higher,
then this option can be de-selected. This will speed up the meter reading process. However, if
this option is not selected and an attempt to read a meter with firmware older than 4.X is made,
the read process will fail in a communications error.
Figure 3

5.4 Reading, Updating, and Programming Meter I.D.
To read a meter, click on the Read Meter button located at bottom left. The empty fields will
populate as the status bar indicates level of completion. The user can navigate through the
program with the rest of the tabs. An example is shown in Figure 3. This initial reading
provides the user with basic information such as date, time, serial number and firmware version.
Here the user may see if a battery or switch is present in the meter.
To send settings to the meter, click on the Program Meter button located at the bottom right
corner.
Once read, the meter firmware version will display in the center box. The user may update meter
firmware by clicking on Update Firmware (Figure 3). The user will be prompted to select a
firmware file from the computer to send to the meter. This is available only in Supervisor mode.
A filed for Meter Settings # is provided for customer convenience. If desired, the user can input
any 2-digit number indicating the number of times the meter has been programmed. For instance,
if the meter is receiving its first configuration, the user may want to insert “01” in this field. This
would allow the user to determine if a meter (perhaps deployed to the field) has received the most
recent programming or any at all. This field is purely optional for the user and may be left blank
(or “00”).
The Meter ID allows a user-customized ID to be sent the meter. This number may not exceed 20
alpha-numeric) characters. The ID is sent to the meter using the Program Meter ID button.
5.5 Current Limit Disconnect Switch
Some meter models are equipped with battery and/or current limit (shut-down) switch, as shown
in Figure 3-1 on the following page. These meters allow the user to set a maximum limit of
current the meter is to provide. If current usage exceeds the defined limit, the meter will
disconnect utility service.
If the meter is equipped with a current limit switch, Open & Close buttons are visible. When the
switch is Open, the utility service is disconnected. The status of the switch will be displayed as
either Charging or Ready. It takes approximately one minute to charge the capacitor to change
the position of the switch. When charging is complete, Ready will be displayed prompting the
user to change the position if desired.

Figure 3-1
5.6 Validation and Reset
The user has the option to validate any/all changes to the meter by checking the Validate box
followed by clicking the Program Meter button. The user may also reset register values by
checking the Reset Values box followed by clicking the Program Meter button. This will reset
errors, demand and registers. This action does not reset the event logs or load profiles.
Other aspects of the meter are seen in the remaining boxes (date, time, SN, etc.). Many of these
items may be changed or reset under other screens which will be discussed throughout this
manual.
6. Settings Screen
The second tab displays the Settings screen (Figure 4). This screen allows the user to read or set
the following:


6.1 Meter Form
The meter form must be chosen first as it makes any other associated options available. The
meter form selection is made at the top left corner of this screen. This parameter is listed on the
nameplate of the meter (FM 2S, FM 3S, FM 16S, etc.). Simply click the appropriate radial box
and that form will be highlighted red. Depending on meter form chosen, some items on the
Settings screen may disappear or become “grayed-out” since they are not associated with the
chosen form.
6.2 Transformer Ratio
This selection will be available automatically for transformer-rated meters (Forms 3, 4, 5, 6, 8, 9,
10) as shown below in Figure 5. Simply select the proper form and the Current transformer CTR
and Voltage transformer PTR (Potential Transformer) ratios can be entered and stored in the
meter.
Example: If a Current Transformer ratio is 200:5 then the user should simply enter 200 in this
box. If register values such as kWh and kW demand also need to be multiplied, check the
kWh=kWh*(VTR*CTR) box located at the bottom of this section. Leaving this box unchecked
will cause the meter to display only raw kWh and kW but only multiply currents and voltages for
display purposes.
Note: Potential Transformer ratios will always be N:1 and Current Transformer ratios will always be N:5.

Figure 5
6.3 Configuration
This section defines whether or not the meter is equipped with battery/switch hardware and how
these items behave. It is important that the user confirm that the meter is equipped with
battery/switch hardware prior to selecting these options.
LCD Mode is used to provide battery power to the meter’s display when the power line is
disrupted. The selection can be either on or off. LCD Mode cannot be selected without fist
selecting Battery.
Switch Board will automatically be checked after reading a meter equipped with a current limit
switch (see section 5.5). However, in cases where the current limit switch is not recognized and
is confirmed to be present, the user can select this option.
6.4 Meter Settings
This setting configures the value the meter uses internally to output pulses for testing and
measuring purposes, in Kilowatt-hours per meter pulse. The Kh represents the amount of energy
usage that will be transmitted through the Optical Port. The Kh value is usually mandated by the
company deploying the meter, and is therefore a user-defined field. Vision meters are shipped
with the following default Kh settings:


Form 1S, 2S, 3S, 4S, 5S, 6S, 8S, 9S, 12S, 25S = 1.0 Kh
Form 16S, 12S-D and 2S-D = 10.0 Kh
12
6.5 Reverse Allowed
This option is used in cases where a secondary power distribution method is employed, such as
solar or wind power generation. Checking this box will allow recording kWh in both directions.
If the user desires “Delivered Only”, the Reverse Allowed box must be left unchecked. Selecting
any items under the “Energy Received” or “kWh net” section of the Display Setting (section 7)
screen will automatically check this box. If any of those items are checked and the user attempts
to de-select “Reverse Allowed”, a message box will appear as in Figure 6 (following page).
Figure 6
6.6 Pulse Output Option
Some models of meters are equipped with optional pulse output(s). If a meter is so equipped it
will be necessary to set the value of each pulse. The Kp is the value assigned to each pulse in
terms of watt-hours per pulse. The value can be set from 1 to a maximum of 65,535 watt-hours
per pulse.
13
6.7 Time Settings
The System Time field provides the user with the system (PC) clock information (Date, Time
and Day). The system time zone may be changed by clicking the Change button and then
selecting the appropriate time zone. Meter Time indicates current time/date information
programmed to the meter. The Set Meter Time button will synchronize the meter clock with the
system clock. This segment also provides the user with the DST (Daylight Saving Time) settings
as per the system clock.
If a “Time Of Use” (TOU) program is to be employed with battery-equipped meters, the date and
time fields are required to be sent the meter.
Date/Time formats cannot be changed (mm/dd/yyyy, etc.).
Note: If the meter is required to transmit Date/Time via ERT, select the date format on the AMR
screen
(section Intervals
8).
6.8 Demand
Located at the center of the Settings screen is the Demand Intervals section which consists of
four fields:




Interval Type which can be None, Block or Rolling. Block creates a simple interval
time length. Rolling allows for sub-interval lengths.
Interval Length is selectable from the dropdown menu. If Rolling Demand is selected,
the Demand sub-interval length must be selected followed by number of subintervals.
Example: Selecting a 30 minute rolling interval with 6 sub-intervals results 5-minute
lengths (i.e. 5 minutes x 6 intervals = 30 minutes).
Demand Lockout Time provides the time span after demand reset until it may be reset
again. This is designated in minutes up to a maximum of 255.
Demand Power Up Time allows the user to set a delay for demand, after power to the
meter is restored.
6.9 Automatic Demand Reset
Depending on the demand selection, the user may choose an automatic demand reset schedule. If
the demand is set as None, the automatic demand reset section will not be available. If either
Rolling or Block is selected as demand then the automatic demand reset becomes available and
the selection between None, Daily, Weekly, Monthly or Custom also becomes selectable. This
is shown below in Figure 7. Clicking on the Program Demand button sends the desired
selections to the meter. Clicking on the Reset Demand button resets the demand register. The
user may also read the current demand settings of the meter by clicking the Read Demand
Settings button.

Figure 15
8.1 AMR (ERT) Protocol
There are two different RF protocols available either independently or simultaneously:


SCM (which is the ERT transmission, compatible with Itron’s ERT™ system)
Vision Data on Demand protocol, requiring the use of a Vision Metering RadioGate
collector.
If the meter is not equipped with a radio or if the radio is not needed, then the radio off radial box
should be checked. IDM is the interval data message.
8.2 Packet Information
The Signal Strength allows the user to set the strength of the radio transmission, selectable from
1(min) to 20(max).
The Transmission Interval allows the user to set the time between the ERT or Data on Demand
transmissions. The most commonly used settings are between 2 and 30 seconds. Likewise, the
IDM Usage Interval can also be set. The user may choose between 1.25, 1.5 or 5 minute intervals.
8.3 ERT Type
There are three ERT types supported by Vision 20/20. Single-phase meters are typically set to 5,
but some utilities use 8. Poly-phase meters are typically set to 8. Meters equipped with multiple
ERT’s default to type 8. If IDM Only is selected under AMR Protocol, then the ERT type will
default to type 23.
19
8.4 Packet Structure
The packet structure is the stream of data which is sent from the meter for use with theVision
Data on Demand system. The Vision Data on Demand system requires several parameters to be
broadcast from the meter. Two items are user-selectable:


Line item #3: Choices are mVa, kW Max.
Line item #4: Choices are Received Energy Volt or Date-Time.
Note: Packet selections programmed to meter must match structure in the EndSight software suite
provided with the Vision Data on Demand system using the RadioGate collector system.
8.5 Multiple ERT (SCM) Transmission
If the meter is equipped with one Airpoint, it will transmit readings. Vision 20/20 supports up to
five ERT’s. By clicking the dropdown menu for each ERT the user may select the desired value
to transmit and subsequently select the decimal place as well (Figure 16). The user may read the
AMR settings that are currently programmed to the meter by clicking the Read AMR button
located at the bottom right corner. Once all the values have been selected for programming, the
user may send all the AMR selections to the meter by clicking the Program AMR button also
located at the bottom right corner.

10. TOU (Time Of Use) Settings
The TOU screen is shown in Figure 18-1. At the top left corner is a field labeled TOU
Schedule. If the selection is None, then the entire screen remains blank with the exception of the
Clear TOU Tables button, used to erase any current TOU tables in the meter. With the selection
of Open TOU Schedule the user is prompted to open a previously saved TOU file. By choosing
New TOU Schedule, the user is presented with the TOU schedule programmer as shown in
Figure 18-2.
Available for programming to the user:
● Up to 4 programmable seasons
● Up to 4 Schedules per day
● Saturdays and Sundays can be treated as holidays or Non-Time of Use
● 10 year calendar with a separate holiday schedule for recurring and nonrecurring
holidays.
Note:



Maximum of 64 tier schedule records can be entered for all four seasons
Maximum of 68 non-Rec dates
Maximum of 28 Fixed-Rec or Float-Rec dates
The Day Type Schedule is located at the top of the screen. Monday through Friday is Type 1.
Saturday and Sunday are selectable between Type 2 and Type 3. The “Type” is used to tell the
meter which Tier Schedule from which to draw instructions. Type 1 typically has the complex
schedule of up to 4 seasons and up to 4 rates per day in each season. Programming this schedule
is complex and should be thought through thoroughly before programming any variables.
The Tier Schedule has four tabs for each of the four seasons. There can be as few as one season
or as many as four, with the seasons being defined by the calendar located at the bottom of the
screen. It is necessary to select the desired type of season before selecting the season start date.
These options are located at center right of the screen and are Automatic Season Change,
Automatic Season Change with Demand Reset (a demand reset will be performed at the time
of season change).
The Calendar Section is located at the bottom and it contains three tabs to choose from: NonRec (this is a non-recurring schedule where all the dates change from year to year), Fixed-Rec
(this is a fixed date like Christmas, New Year’s or 4th of July) and Float-Rec (this is where the
calendar is fixed and changes are made based on floating dates like Memorial Day or Labor Day.
A schedule may be developed for each one of these categories. Under each header click on the
field and choose from the dropdown menu.
In the Tier Schedule, click on the fields under: Schedule, Hour, Minute and Rate and select
choice from the dropdown menu. Under Calendar: click on the fields under Month, Date, Year
and Action and select choice from the dropdown menu.

The user may use the Read TOU button to read the current TOU settings on the meter. Once the
meter has been read and changes have been made to setting selections, the modified settings may
be sent back to the meter utilizing the Program Updates button.
The TOU settings may be saved as a file to the PC by selecting “Save” or “Save as” under the
File menu from the main task bar. The Program TOU button is ideal for sending the chosen
settings (TOU file) repeatedly to multiple meters.
11. Load Profile Settings
11.1 Load Profile Settings
Load profiles are tabular data which are recorded by the meter in terms of load versus time. The
Load Profile Settings screen is shown in Figure 19. There are 12 channels (load characteristics)
of Load Profile settings available in the meter. After selecting the number of channels desired,
each channel may be set to a particular value from the dropdown menu for individual channels.
The values stored in the load profile are in the form of pulses and directly relate to the Kh of the
