CDM-710/L Broadcast Satellite Modem
Front Panel Operation
(Config:) Intfc1 HSSI: Rx Buffer Recenter
The value in parentheses (e.g., 046%) indicates the current buffer fill status.
To reset the buffer to the midpoint (50%), use the arrows keys to select
ReCENTER. Press ENTER.
(Config:) Intfc1 HSSI: Rx Clock
Use the arrow keys to select Source or Invert. Press ENTER.
(Config:) Intfc1 HSSI: Rx Clock Source
Use this menu to determine which source clocks the output of the Rx Buffer for
delivering data to the Rx port at the user interface. Use the arrows keys to
select Rx-Sat, Tx-Terr, or Internal. Press ENTER. Note that:
• Rx-Sat, the default, disables the Rx Buffer because the input and output
clocks are the same. Normally, the Rx Buffer is set for minimum when Rx-
Sat is selected.
• Tx-Terr uses the clock from the Tx input (TT) to clock out the Rx Buffer.
• Internal derives a clock from the internal 10 MHz reference clock.
(Config:) Intfc1 HSSI: Rx Clock Invert
Use this menu to control clock inversion (to ensure compatibility with certain
older equipment). Use the arrows keys to select Normal or Inverted. Press
ENTER.
