The diagram below illustrates the wiring to multiple GV-Control Centers and uses GV-NET

Figure 2-4
Note:
1. Because RS-485 communication has distance limitation, the distance between each
Keyboard and the GV-Control Center 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-Control Centers and switch control among
these servers, see
2.4.2 Setting a Keyboard for Multiple GV-Control Centers
