Installing the GPS antenna
Note

in
.
1. Slide the antenna mounting pole down over the antenna cable so that the cable passes
through the center of the pole.
2. Take the end of the cable that has passed through the pole and screw the antenna onto
the cable by turning the antenna.
3. Screw the antenna down on the mounting pole by turning the pole.
4. Use the saddle straps to mount the antenna mast in an area where the antenna has an
unobstructed view of 30° above the horizon.
5. After running the cable from the S100 location to the antenna, attach the cable to the
antenna.
6.
Optional:
Connect the modem phone line to the card on the back of the S100.
7.
Optional:
Connect the chassis ground and install nut (not provided).
8. On the back panel of the S100,

green
LED in the
front panel comes on. When the hard drive is active, a
red
LED light comes on.
Connecting the Rubidium Option
If you are using the optional Rubidium oscillator, the external SS X72 cable needs to be
attached for proper operation. Facing the rear panel of the S100, connect the SS X72 cable
from the DB15 connector to the DB9 connector, forming a single loop. If your unit has no DB9
connector, there is no rubidium in the S100.
Establishing A Serial Connection
This step is necessary to establish the S100’s IP address. The only time you will need to
make a serial connection with the S100 is during setup. Once the S100 has an IP address,
improper shutdown or power failures will not cause the IP address to be lost, also, you will
use the web-based interface for communication.
Note:
To test the S100 prior to installation, you will need three Ethernet cables and a hub
(see diagram below). Connect the supplied Serial cable from your computer to the front of
the S100. Connect the S100 and the computer to the hub using two Ethernet cables. You
can perform an off-network test at this point. When you have completed the test, connect
