CDM-570L/570AL Satellite Modem with Optional Packet Processor
Revision 5
Optional High Performance Packet Processor D–23 MN-CDM570A
D.2 High-Performance Packet Processor – Quick Start Guide
This section serves to guide you through the steps needed to pass IP traffic within minutes of
initial installation and setup (i.e., starting from factory default settings), using a pair of
CDM-570A/570AL-IPs. This section refers generically to any Comtech EF Data IP-centric
modem as the CDM-IP.
This section assumes operator familiarity with configuration of base modem ooperations.
D.2.1 Getting Started
D.2.1.1 Equipment List
Use the following equipment:
CDM-570A/570AL Satellite Modem w/optional Packet Processor and/or
any other compatible, IP-centric Comtech EF Data modem.
Note: You may need to provide equipment to convert 70 MHz IF to
L-Band for a duplex connection, depending upon modems.
Layer 2 Ethernet Switch or Hub
Note: RJ-45 crossover Ethernet cables can be substituted to directly
connect the User PC to the CDM-IP Modem without the use of a hub.
Windows-based PC with Network
Interface Card (NIC), terminal
emulation program, and
Console cable (DB-9 to RJ-11)
Supplied by Comtech EF Data (CEFD P/N PL/9396-1).
Supplied by User to interconnect Tx-Rx between both CDM-IP modems.
D.2.1.2 Equipment Setup
Do these steps:
Use CAT5 Ethernet cables to connect each CDM-IP rear panel “Traffic 100” port to the User PC via the
Ethernet hub or switch.
Use coaxial cables to connect the Tx IF on CDM-IP 1 to Rx IF of CDM-IP 2, and the Rx IF on CDM-IP 1 to
the Tx IF of CDM-IP 2.
Connect the DB-9 end of the CEFD P/N PL/9396-1 console cable to the COM1 or COM2 port of the User
PC, and the RJ-11 end to the CDM-IP 1 rear panel Console port.
Connect the CDM-IP 1 and CDM-IP 2 to suitable power supplies and turn them ON.
