CDM-710/L Broadcast Satellite Modem
Introduction
Item 6 – 'J4 | ETHERNET' Ethernet Management Utility Port
Use this 10/100 Base-T Ethernet RJ-45 port for operation of the Ethernet remote
control interfaces.
Item 7 – 'P1 | ALARMS' Utility Connector
Use this DB-15M EIA-232 connector to access the Form C Alarms (relay closures).
Item 8 – 'P2 | Remote' Serial Management Utility Connector
Use this DB-9M EIA-232/EIA-485 connector for operation of the Serial Interface.
Item 9 – 'J7 | Rx (Receive)' IF Connector
CAUTION
THERE MAY BE DC VOLTAGES OF UP TO 48 VOLTS MAXIMUM PRESENT
ON THIS CONNECTOR.
Use this connector for Rx operation:
• CDM-710 (70/140 MHz) – BNC female connector
• CDM-710L (L-Band) – Type 'N' female connector
Item 10 – 'J6 | Async Channel' Utility Connector
1) Asynchronous Engineering Channel operation is not implemented in
the CDM-710/L; this DB-9F connection is therefore non-operational.
2) This connection exists on Rev. A and later chassis only. The original
production unit provided an RJ-45 connector, labeled 'J6 | SerDes'. It
served as a private communications link and was not intended for
customer use.
