Technical Specifications

Reader Data Connector

6-pin terminal block supporting RS485 and Wiegand protocols for communication with the reader.

The RS485 ports support:

•Two-wire RS485 half duplex

•Four-wire RS485 full duplex

The Wiegand ports support:

• Two-wire Wiegand

Function		Pin	Notes
RS485	A-	1	For full duplex RS485
			For half duplex RS485
	B+	2
RS485	A-	3	For full duplex RS485
			For half duplex RS485
	B+	4
Wiegand	D0 (Data 0)	5	For Wiegand
	D1 (Data 1)	6

Important

The recommended maximum cable length is 30 m (98.4 ft).

Reader I/O Connector

6-pin terminal block for:

•Auxiliary power (DC output)

•Digital Input

•Digital Output

•0 V DC (-)

Pin 3 on the reader I/O connectors can be supervised. If the connection is interrupted, an event is activated. To use supervised inputs, install end of line resistors. Use the connection diagram for supervised inputs. See page 62.

Function	Pin	Notes	Specifications
0 V DC (-)	1		0 V DC
DC output	2	For powering auxiliary equipment.	12 V DC
		Note: This pin can only be used as power out.	Max load = 300 mA
Configurable (Input	3–6	Digital input — Connect to pin 1 to activate, or leave	0 to max 40 V DC
or Output)		floating (unconnected) to deactivate.
		Digital output — Connect to pin 1 to activate, or leave	0 to max 40 V DC, open drain,
		floating (unconnected) to deactivate. If used with an	100 mA
		inductive load, e.g. a relay, a diode must be connected
		in parallel with the load, for protection against voltage
		transients.
