Ethernet Cables
The operator provides the Ethernet cables between the CMM4 and the radios it supports. They
must be engineered to length and are not included with the CMM4. The cable length from the
CMM4 to any radio must be under 100 m (328 ft).
Cables are available from Best-Tronics, Inc.,
. These cables can be ordered
in lengths up to 328 ft (100 m) and are listed in

IMPORTANT!
Shielded Ethernet cable is strongly recommended for AP and BH
installations.
Alternatively, equivalent cables may be procured by the operator, fabricated by the operator in a
depot, or fabricated at site. The modules have auto MDX/MDIX and so either straight-through or
crossover Ethernet cables may be used. Pinouts for straight-through cables are shown in
shows the location of Pin 1, relative to the lock tab on the connector.
