SW 1 Beeper Control
The default mode for the Beeper Control is the internal control. When the setting
is “On”, the Reader is sounded after a card is read. When the setting is “Off”, the
Beeper is controlled externally. You can use the external beeper control line to
activate the beeper.
SW2-SW3 Green/Red LED Control
The default mode for the Green/Red LED Control is the internal control. The
LED is normally red. When a card is read, the LED flashes green. When the
setting is “Off”, the Green/Red LED is controlled externally. The external control
lines can then be used to operate the LEDs.
SW4 Master/Slave
The switch is used to select the Reader’s communication interface. When the
setting is “On”, the Reader is controlled by Wiegand signal. When the setting is
“Off”, the Reader is for RS-485 signal.
SW5-SW7 ID Setting
Switch 5 to switch 7 is used to set the Reader’s ID during a chain connection.

SW8 RS-485 Terminal Resistor
When the setting is “On,” a 120-ohm resistor is connected between RS-485+
and RS-485-. This setting is used in the last device when multiple RS-485
devices are connected together.
NOTE: After changing the dip switch settings, the unit must be reset by
powering down then up again before the new switch setting will take effect.
Wiring Connection
The GV-Reader is compatible with any standard access controllers. The
following diagrams illustrate how to connect the GV-Reader to GV-AS Controller
through Wiegand interface or RS-485 interface, and how to connect the GVReader to third-party access controllers and GV-System.
After you wire the connection between the GV-Reader and the access controller,
ensure the related switch setting on the GV-Reader is configured correctly.

Note: Each reader consumes 60 mA of power. The total power consumption of
the output devices and readers connected to the GV-AS Controller must be
under 3A (for GV-AS210 / 2110), 3.5A (for GV-AS410 / 4110) or 5A (for GVAS810 / 8110). Connect an external power supply if the power supplied from GVAS Controller is insufficient.
