The PCIDM V2 has two channels.
Channel 1 supports NRZ, and Packet Mode.
Channel 2 supports NRZ, Packet, ASK, and FSK Mode.

The PCIDM currently supports MIL-STD-188-220, AFAPD,
Tacfire, MTS, IDL, and MIL-STD-188-184.

The PCIDM protocol stacks are compatible with the protocol
stacks used in the IDM 302, IDM 303, and IDM 304.
The PCIDM and IDM share a lot of the same protocol source code (ex: AFAPD, TACFIRE,
MIL-STD-188-220).

The PCIDM User's Manual contains a cable diagram for each radio
interface cable we sell.
Integrating the PCIDM with a new radio usually consist of
creating a new cable, and conducting some functional tests.
Several customers have developed their own radio interface
cables.

There are three levels of interface to the PCIDM.
1.
Graphical User
Interface
The PCIDM comes with
AMPGUI, which is a graphical user interface that allows the
user to send and receive messages very simply.
2.
AMP Interface (High
level programmatic interface)
The PCIDM comes with
windows library (AMP.DLL) to facilitate integration of
customer user interfaces. This library (called AMP) takes
care of the laborious task of parsing the over the air
messages into simple ‘C’ structures containing the message
information in engineering units. The AMP library currently
supports the F16 message set (X202 9 line brief, X204,
S100), and some of the Apache message set (A501,
A301, …).
3.
UDP Interface (Low
level programmatic interface)
The lowest level
interface to the PCIDM protocol stack is through UDP.
Sending a UDP datagram to the PCIDM will cause the PCIDM to
transmit a message over the air. When the PCIDM receives
a over the air message, the
message is sent to each registered application as a UDP
datagram. The UDP datagrams
contain the raw over the air messages.

There are 4 ways to configure the PCIDM or UIDM.
1.
AMPGUI PCIDM V2
Configuration Dialog
AMPGUI includes a configuration dialog to
allows the user to customize the
PCIDM settings by simply pointing and clicking.
2.
AMPGUI MIB Loader
AMPGUI includes a script driven configuration tool that
allows the user to configure a group and settings in a
single click of the mouse.
3.
PCIDM SDK
(Software Development Kit)
The PCIDM SDK includes an SNMP manager that allows the user
to make set and get calls to configure the PCIDM V2
programmatically.
4.
SNMP (Simple Network
Management Protocol)
All PCIDM configuration is done via SNMP. A third party
SNMP manager can be used to configure the PCIDM MIB.

The PCIDM V2 and UIDM V2 share a substantial amount of circuitry
and run the same PCIDM software (ex: PCIDM V2.91). AMPGUI
and the PCIDM SDK work with both the PCIDM V2 and UIDM V2
hardware. All PCIDM V2 radio cables will work with the
UIDM V2.
The PCIDM V2 is a PCMCIA card that is typically inserted
into a PCMCIA card slot within a host computer. The
UIDM V2 is a stand alone device that includes an ethernet
interface for communication with one or more host computers.
The PCIDM stores its non-volatile configuration on the host
computer. The UIDM stores its configuration in an
on-board non-volatile memory device. The UIDM V2
revision 2 has undergone extensive environmental testing to
verify its suitability for rugged military environments.

The only way to be sure the PCIDM will work in your PC is to
test it. The PCIDM has been proven to work in wide range
of laptop computers, and a few desktop computers with PCMCIA
card drives.
