Figure 1-8<br />
Connect two power wires and two RS-485 wires from <strong>GV</strong>-<strong>AS</strong>Box/<strong>GV</strong>-<strong>AS</strong>Net to <strong>GV</strong>-<strong>AS</strong>100.<br />
The table below shows the pin assignments of related connectors on <strong>GV</strong>-<strong>AS</strong>100.<br />
Pin Function Pin Function<br />
1 Power In 12V 3 RS-485 A+<br />
2 GND 4 RS-485 A-<br />
Also see 4.1.4.A Connecting <strong>GV</strong>-<strong>AS</strong>100/<strong>GV</strong>-<strong>AS</strong>110/<strong>GV</strong>-<strong>AS</strong>120.<br />
1.2.4.C Switches<br />
Switch 1: When Switch 1 is ON, <strong>GV</strong>-<strong>AS</strong>100 can connect to <strong>GV</strong>-<strong>AS</strong>Manager, <strong>GV</strong>-<strong>AS</strong>Box or<br />
<strong>GV</strong>-<strong>AS</strong>Net. When Switch 1 is OFF, the connection is unavailable. By default Switch 1 is set<br />
to ON.<br />
Switch 2: When the RS-485 connection between <strong>GV</strong>-<strong>AS</strong>100 and computer is longer than<br />
600 meters (1968.50 feet), the RS-485 signal may become weak. In this case, turn Switch 2<br />
ON to have a 120-Ohm resistor.<br />
