Connecting five or more readers to GV-AS410 Controller:
For readers five to eight, wire RS-485 cables to the RS-485 interface on GV-AS410 and
then wire the 12V power and GND cables of each reader to a 12V DC power output on
the controller.
Note: When multiple readers are connected together, an extra power supply to each unit is
required. Use 12V power output and GND on the power terminal to power on each unit.
