CDM-600/600L Emulation Indication – The CDM-625A serves as a 'drop-in' replacement
product for CDM-600 and CDM-600L modems. An emulation mode is provided to
accomplish this design intent, and is configurable via either the front panel (SELECT:
UtilityEm) or by remote control (remote command EMU=).
When emulating a CDM-600 or CDM-600L modem, the CDM-625A opening screen displays
the mode of operation, as per this example:
Comtech CDM625A
TPC, PktP present
Note that, while emulating a CDM-600 or CDM-600L modem, the I/O responses (including
that of remote query EID?) replicate those of the emulated modem; further, the firmware
version number displayed on the opening screen, and the response from the SWR? remote
query reflects that of the emulated modem's firmware version number.
•
Warm-up Delay Mode counter – When selecting the warm-up delay mode, the modem
turns the carrier off during the warm-up time and the countdown message "High-
Stability Ref Warming up : ### sec" displays on the bottom line of the screen
as follows:
