(ODU) (TRANSCEIVER, BUC,

10.1 Overview

The CDM-425 Advanced Satellite Modem permits configuration, monitoring, and control of
Comtech EF Data ODUs (Outdoor Units) either in standalone or 1:1 redundant configuration.
The following ODUs are compatible under 70/140 MHz operation:
•
CSAT-5060 series (5 to 25, 50 & 100 Watts) C-Band Transceivers
•
KST-2000A (LNA) Ku-Band Satellite Transceiver
•
KST-2000B (LNB) Ku-Band Satellite Transceiver
Under L-Band operation, ODU refers to use of a Comtech EF Data LPOD Outdoor Amplifier /
Block Up Converter (BUC), or an LNB (Low-Noise Block Down Converter).
For either 70/140 MHz or L-Band operation, you may fully monitor and control ODU operations in
the following ways:
•
By using the CDM-425 front panel keypad and VFD. The Front Panel ODU menu branch
allows you to configure power supplies, a 10 MHz reference, and low/high current alarm
thresholds for the BUC and LNB.
•
LO (Local Oscillator) menus allow you to set up the upconversion and downconversion
settings for the BUC and LNB so that you can view the satellite frequencies as well as the
modem IF input/output frequencies.
•
By using ODU remote commands through Serial-based Remote Product Management
with the CSAT-5060 or KST-2000A/B Transceiver, or the LPOD.
•
By using the SNMP Interface with the CSAT-5060 or KST-2000A/B Transceiver MIB.
•
By using the CDM-425 HTTP (Web Server) Interface (excluding the LPOD).
•
By using the CDM-425 Telnet Command Line Interface for CSAT-5060 Transceiver
operation (excluding the KST-2000A/B Transceiver or the LPOD).
