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 SEM2411X, 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 rear
of the SEM. 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.
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.
