CDM-425 Advanced Satellite Modem
Revision 0
Front Panel Operation 6–44 MN-CDM-425
6.2.1.9 CONFIG: EDMAC
Appendix H. EDMAC CHANNEL
Embedded Distant-end Monitor and Control (EDMAC) is a Comtech-proprietary framing that
permits communication access to the distant-end modem.
Without the proper active framing mode, the menu appears as follows:
EDMAC Mode= Idle (Idle,Master,Slave)
(

)
You must otherwise use the CONFIG: Mode menu to set framing for EDMAC, EDMAC-2,
EDMAC-3, or D&I++.
With the proper active framing mode, the menu appears as follows:
EDMAC Mode= Master (Idle,Master,Slave)
EDMAC Address= 0020 (

)
Use the
▲▼ arrow keys to select the mode as
Idle , Master , or Slave . Press ENTER .
If the mode is Master or Slave , the bottom line shows an address. To edit the address, use the
◄ ►
arrow keys to select a digit, and then use the
▲▼ arrow keys to change that digit. Press
ENTER .
Note that:
•
An EDMAC Master is a modem that is local to the M&C computer, and which passes
messages, via the overhead, to a distant-end modem. The Master address always ends
in
‘0’ .
•
An EDMAC Slave is a modem that is not local to the M&C computer. It is at the ‘distant-
end’ of a satellite link. The Slave EDMAC address always ends in ‘
1’ . When configured
as a Slave , reconfiguration is expected to be via the EDMAC link, and is therefore not
permitted via the front panel or via serial remote control.
