Care must be taken to follow the color code correctly. An incorrectly assembled connector can

damage the radio or the card or both. The picture below shows the completed cable assembly.

Important Note:

If an alternate source of power is used with the SEM2410DX, it must be limited to

+12VDC +/-10%. Failure to meet this specification can result in damage to the

remote radio assembly.

Connectors

The 10/100BaseT Ethernet connector is the standard RJ-45 connector and is located on the front

of the SEM2410DX and the rear of the SEM2410X. The SEM is set up to use a straight through

cable to connect to a PC. If a straight through cable is used to connect the SEM to other devices

through a hub, the SEM must be connected to the uplink port on the hub. Both a straight-through

and a crossover Ethernet cable are included.

The SYNC IN and SYNC OUT signals are provided for special applications where multiple

master SEMs are co-located. The synchronizing signals are RS-485 levels and may be connected

using an RJ-11 connector. If the sync signals are required, one of the master SEMs must be

designated as the sync master. See the section SEM/Radio Commands for details. If there are no

co-located master SEMs, sync should be left disabled.

The Console port is an RS-232 serial port that may be used to configure the SEM. Connection to

this port is made with the 9-pin to RJ-11 serial cable included with the SEM. This is useful when

the default IP address of the SEM cannot be used with the existing network preventing

configuration through a telnet session. See the section Configuring the SEM for details of using

this port.
