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.

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 the change of dip switch settings, the unit must be reset by powering down
then up again before the new switch setting will take effect.
