For Wiring to an RS-485 port:

1.TR+ is the plus side of the transmit and receive differential signal.

2.TR- is the negative side of the transmit and receive differential signal.

3.GND is the signal ground. The wiring for this signal is required and NOT optional. This signal must NOT be connected to chassis GND.

4.Use 24 AWG low capacitance, two twisted-pair, shielded cable (Belden 9842 or equivalent).

Common

Note: For N-485 Communication Connections, twist the blue pair together and use as the common; use the orange pair as your data pair, observing polarity. Connect the external drain shield to the appropriate earth ground on one end.

5.When daisy-chaining RS-485 ports together connect the TR+ wires from the upstream and downstream boards to the TR+ terminal and likewise, connect the TR– wires from the upstream and downstream boards to the TR– terminal.

By factory default J1 is set open. If this board is the last board on the RS-485 bus, install jumper J1 across both pins (closed). Closing J1 provides the bus termination required.

Reader Wiring

Each reader port supports a reader with TTL interface. Power to the reader is selectable as 5 VDC or 12 VDC (pass-through). This selection is done via setting of jumpers J2 for reader 1 and J3 for reader 2. Set jumper at position “5" for 5 VDC or “12” for pass-through 12 VDC. The factory defaults set J2 and J3 to “5”.

For wiring to a reader port:

Terminal	Typ Wire Color	Wiegand Reader	Clock/Data Reader
1	Red	Power (5 or 12 Vdc)	Power (5 or 12 Vdc)
2	Brown	LED control	LED control
3	Yellow	Beeper Control	Beeper Control
4	White	Data 1 Signal	Clock Signal
5	Green	Data 0 Signal	Data Signal
6	Black	Common	Common

The LED control terminal in each reader port can be configured via host software to support one-wire single or bi-colored reader LED. An example of the most common configuration is shown below. If Beeper control is not used, its terminal can be pro- grammed to be the 2nd wire for the two-wire bi-colored reader LED.
