Step 2
– Fitting the antenna
The router is supplied with a “stub” aerial and an elbow adapter for use with wireless
networks.
There are two options for fitting the antenna:
1) If the unit is to be mounted on a flat surface such as a desktop, you should first screw
the antenna onto the 90
elbow adapter supplied. The pair may then be screwed onto
the SMA connector on the rear panel of the router. DO NOT OVERTIGHTEN THE
ANTENNA
– IT SHOULD BE FINGER TIGHT ONLY.
2) If you intend to mount the router on a wall (or other vertical surface), using the
mounting bracket, the antenna may be fitted directly to the SMA connector without the
elbow adapter.
Important Note
If the HSUPA option is purchased, 2 antennas will be supplied, both must be attached to
the router. These antennas must not be replaced with external antennas as the spacing
between the two antennas is critical.
Step 3
– Connecting the LAN cable
Plug one end of one of the supplied 2 metre CAT5 cable into the RJ45 socket labelled
LAN 0. Plug the other end into the LAN socket on your PC or notebook.
Step 4
– Connecting the serial cable
For connection to a serial terminal device, connect the 25-way D plug on the serial cable
provided to the SERIAL connector on the rear of the unit. Connect the other end of the
cable (9-way D socket) to the terminal. If the serial connector on the terminal is not a 9-
way D plug, you will need a suitable adapter.
Step 5
– Connecting the power supply
Plug the jack plug on the mains adapter into the socket labelled 12V DC. When power is
first applied, the ON indicator will illuminate and the unit will initiate a series of diagnostic
self-tests. During this process one or more of the other indicators, will flash to show that
the unit is busy. When the flashing stops, the unit is ready to use.
The unit is now ready to be configured.
