CDM-600/600L Emulation Indication – The CDM-625A serves as a 'drop-in' replacement
product for CDM-600 and CDM-600L modems. Comtech EF Data provides an emulation
mode to accomplish this design intent. You may configure this mode via the front panel
(SELECT: UtilityEm) or by remote control (remote command EMU=).
When you select emulation, the CDM-625A opening screen displays this mode of operation,
as this example shows:

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 remote query
SWR? reflects that of the emulated modem's firmware version number.
•
Warm-up Delay Mode counter – When you select the warm-up delay mode, the modem
turns the carrier off during the warm-up time, and the bottom line of the screen displays the
countdown message:
