The diagram below illustrates the wiring to multiple GV-Systems and uses GV-NET Card as
RS-485/RS232 interface converter as example.
Figure 1-4
Note:
1. Because RS-485 communication has distance limitation, the distance between each
Keyboard and the GV-System must be within 600 meters (1968.5 feet).
2. You can only use either USB port or RS-485 port on the Keyboard. Don’t connect the
USB cable on the Keyboard when using RS-485 connection.
To set up the Keyboard to control multiple GV-Systems and switch control among these
servers, see
1.4.2 Setting a Keyboard for Multiple GV-Systems
