ROSS MN/13070
Comtech EF Data CDM-570L, Sea Tel DAC-2202, and ROSS Hardwire Interconnect
Wiring:
The CDM570L is connected to the DAC 2202 ACU through the Terminal Mounting Strip (TMS)
using the Comtech Modem Interface cable assembly 126877-B. The cable assembly is designed
to work with older and newer versions of the TMS, however when using the newer version of the
TMS the +12/24V pull-up connection is not required as there is a voltage pull-up jumper instead.
When using the newer terminal PCBA with pull-up jumper, clip the +12/24V line from cable
assembly. See Comtech Modem Interface Cable Assembly, Figure 12.
