3.3.1 SLM-5650/5650A Cable Connection Considerations
• If adding a new SLM‐5650/5650A Satellite Modem to an operating 1:1 system, make sure
the new modem does not interfere with existing traffic.
• Make sure the cabling is correct. The following types of cable connections may be used to
connect the CRS‐311 to the SLM‐5650/5650A modems and/or the user:
o System Control
ƒ The CA/WR12136‐2 Control Cable provides the serial communication path between
the CRS‐311 and the modems and controls the modem’s external Tx IF‐mute control
line, and is therefore always required.
o Serial Data Traffic
o Serial User Data
o Ethernet M&C
o Ethernet Data Traffic
o IF
• Perform the power‐up sequence correctly.
