3.24 MEC-9-xx Extension/Interconnect Cable
3.25 RIM-900-BAL Radio Interface Module
3.26 RSM-900, RSM-902 Radio Select Module
The MEC-9-xx Extension/Interconnect Cable is used to
relocate any component with a four conductor Conxall
connector. Not normally sold with a new system, the
MEC-9-xx allows relocation of components when cable
has already been installed and it is not practical to
replace the component to a version with a longer
cable. The cable can also be used if a maintenance
breakaway is needed in a cable run as is the case in a
tractor/trailer configuration. The xx designate the
length feet of the cable.
The Radio Interface Module, RIM-900-BAL, allows
the user to adjust the levels of transmit and receive
audio, TX and RX respectively. The Radio Interface
Module accepts balanced audio input.
The Radio Select Module, RSM-902 and RSM-900,
allows the user to monitor two and three radios
respectively and to transmit on the selected radio. The
Radio Select Module consists of an 18ft cable
terminated with a four-pin Conxall to connect to the
“RADIO” port of the IM-900. There are two or three
one-foot cables terminated with the mating connector
to the “IM-900 end” of the 9RC Radio Cable or MACB-
xx Microphone Adapter Cable. If the radios being
connected to the Radio Select Module have different
transmit level setting, a separate Rim-900-BAL will be
needed for each radio.
