SIM Card Sockets
The two sockets at the right side of the front panel are for the GSM SIM card(s) that you
will receive from your service providers. Details of how to insert these correctly are given
in section 2 below.
CDMA models do not require SIM cards and therefore do not have SIM card sockets.

This socket is used to connect the unit to the power supply using
the 12V DC power supply provided .
The LAN sockets are used to connect the unit to 10/100-BaseT
LANs using the 2-meter STP (Shielded Twisted Pair) cable
supplied or a suitable alternative. These ports are auto-sensing
for speed and wiring (straight-through or cross-over). To comply
with EMC requirements they should not be used with non-STP
cable.
This SMA connector is used to fit the wireless antenna. The
Transport SR-, E and H models are supplied with a single stub
antenna which should be fitted to this connector.
Note: Stub antennas are provided as standard but a range of
suitable alternative for use in different applications may be
purchased separately.
This SMA connector is used on the Transport SR44-U and C
models to fit the second antenna supplied with the unit. The
receiver supports "diversity" antenna capability to improve
performance and are there supplied with two stub antennas. On
models that do not support diversity antennas this connector will
not be present.
