CONNECTIONS
3
If using a shielded cable, it is necessary to link the cable shields together (see
Figure 12) and connect them to the earth ground in only one point.
We suggest to use your PC ground (when provided) to make the connection to the
earth ground.

Network Termination
WARNING
Before proceeding with this operation ensure that the base station
is not powered.
The RS485 bus must be properly terminated by positioning a jumper in the
RS232/485 converter (see the relevant manual) and in the last STARGATE™ on the
network. To position the jumper proceed as follows:
CAUTION
If working with a STARGATE™ USA model, skip step 1 and step 6,
since the antenna is fixed and not removable.
1. remove the STARGATE™ antenna by
unscrewing it (counter-clockwise);
2. unscrew the four cover screws on the base;
3. detach the base from the upper part of the
station;
4. position the jumper as shown in Figure 13;
5. close the base screwing the four cover
screws;
6. install the antenna screwing it clockwise until
tight.
