PCM600
The PCM600 is a state-of-the-art telemetry encoder suitable for data acquisition in virtually any application. The
design of the PCM600 employs custom hybrids, programmable gate arrays, DSP technology and surface mount
technology in a modular configuration. This allows the unit to be customized to meet specific customer requirements
in a small, lightweight, low cost unit.
Standard user interfaces include but are not limited to differential and single-ended analog, bridge completion with
current and voltage excitation, charge amplifier inputs, thermocouples, strain gauges, RTD's, differential and singleended discretes, avionics bus interfaces, and serial and parallel data interfaces.
Channel sampling of all inputs is in accordance with IRIG 106, and setup and formatting information for the encoder
is fully programmable through a personal computer via a serial port. The formatting information, when downloaded, is
stored in non-volatile memory within the PCM600. The frame format information generates the necessary signals to
address channels and select individual setup parameters for each channel of each module. The digitized data from
each channel is then multiplexed into the output serial data stream.
A variety of analog modules are available for typical applications, while the number of channels provided is dependent
on the type of input. The following table lists the module types available, and more detailed descriptions follow in this
brochure. The analog modules are mounted to the appropriate Base Unit for the specific application. Three base
units are available to provide different levels of internal power.
The encoder is user reconfigurable from one to sixteen modules. Modules are stacked on a base unit in any order and
are bolted together with the supplied hardware. The unit is then programmed for the appropriate module
configuration. Alternate mounting configurations are available.

Std. 30W Base Unit, Alt. 30W Base Unit, 70W Base Unit
Every PCM600 contains a Base Unit, which in turn contains a Program Control assembly and a power supply assembly. Data acquisition
modules are then stacked onto the Base Unit in a building block approach to create the desired configuration. The Program Control
assembly provides for the actual formatting of the PCM data stream, and acquires digital data from each of the data acquisition modules
as needed. In addition, the Program Control provides the filtered output necessary for driving a telemetry transmitter. A fixed bit rate
Program Control is offered in support of existing programs which contains this assembly. The programmable bit rate Program Control
is now the standard for the PCM600. The Power Supply assembly converts raw 28V input power to the regulated voltages required
within the PCM600. Three types of power supplies are offered, and their choice is dependent upon the types of data acquisition
modules in the specific encoder configuration. The Standard 30W Power Supply delivers up to 30W of internal power to the PCM600,
and is the common choice for smaller configurations. The Alternate 30W Power Supply also delivers up to 30W of internal power, but
with a different current mix for the various regulated voltages. The 70W Power Supply is typically used for larger configurations, and
theoretically could deliver up to 90W of internal power. For thermal reasons, it is recommended that the power not exceed 70W.

ASD620 - Serial Data Module (2 Channels)
The ASD620 provides a dual-channel asynchronous serial digital
interface to an external source. The ASD620 is a characteroriented data storage device utilizing FIFO (First-In-First-Out)
memory devices. Data can be stored as 8-bit data through 16-bit
data as selected on the PCM600 setup page. The input interface
between the ASD620 and the external source is through RS-422
differential line receivers, with the external source provides a clock,
data and enable signals. The enable signal must be valid when
data is valid and the clock must be a continuous clock. When data
is not available, the data output by the PCM system will be a fill
code of alternate ones’s and zero’s. When data is received, it is
converted to parallel data and buffered through the use of FIFO
memory. The data is read from the FIFO in parallel and converted
to serial for the PCM system interface. The user may specify
different input data, clock and enable timing relationships, as
shown below, at the time of order.

bus or receive RS-422 data with use of sync detection, command
usage, and checksum verification.
The GCI6xx will detect a programmable 24-bit sync (3 words)
pattern from the RS-422 data received. The command words are
transmitted after the sync word and the GCI6xx decodes RS-422
information to initiate up to six relay drivers. Four of the drivers are
timed outputs; the remaining two drivers provide latched outputs.
The GC6xx provides command echo response via RS-422
transmission to the command source, and also provides a
checksum verification on each of the RS-422 frames received. A
status register is used to provide equipment status information to
the command source, which includes status of 7 discrete signals,
FIFO overflow, checksum error, and command errors. Both
command echo and equipment status are transmitted upon
receipt of a command word. Eight discrete signals are also
provided.

Custom Designs
Although a wide range of standard modules are available for the PCM600, there are often occasions where new modules or modified
modules are required to meet the needs of the mission at hand. Numerous ‘special’ modules have been created over the past ten or
more years which have been leveraged from existing standard designs, thereby reducing cost, turn-around time and risk to the end
user. In many cases it is simply a matter of reprogramming an FPGA to provide the desired functionality of a module, while other cases
may require a redesign of some analog front end circuitry to achieve the desired results.
Custom designs are not limited to PCM600 modules; entire encoders have been created for specific applications, where the basic
design of the custom encoder has used the PCM600 design as its basis. Although the PCM600 is a very versatile product which has
been used on many major munitions programs, there are cases where there are special envelope requirements or functional
requirements that the standard PCM600 cannot meet. In these cases, we work with the customer to craft the highest performance and
most cost effective solution for his mission.
If your requirements are such that it does not appear that the standard product PCM600 is a good match, please contact us! We can
help you design a system which can take advantage of the proven performance and reliability of the PCM600, and yet fit the specific
requirements of your mission.

PCM600 User Interface Software & Technical Manual
The PCM600 can be configured in an infinite number of ways, using factory set items in combination with a wide array of user
programmable features. Factory configurable items are typically for parameters which rely on specific component values ... bridge
completion resistors for example. User programmable features are typically hardware related and format related. Hardware related
programmable features are parameters such as gains and offsets, filter cut-off frequencies, delay times, etc. Format related features are
those things that allow the user to construct the overall frame format, and to place words in the format in the order that he prefers, using
the provided software.
The user software is Windows based and is very easy to use. Many customers have used the software to perfect their format and
measurement set, adjusting measurment parameters after successive flights. Using the setup software requires a methodical sequence
of events, first defining the physical configuration of the encoder, and then configuring the programmable parameters for each module.
Once the hardware has been defined and set up, the user then defines the overal frame structure, assigning sync patterns, sub-frame
ID’s and the like. Finally, the user then assigns each word in the format to specific measurements.
A detailled technical manual is also provided which describes the details of each module, how to program each module, and, in general,
how to use and program the PCM600. The user software and technical manual is provided free to each customer, upon delivery of the
hardware.
