Install the termination jumper ONLY on the panel at each end of the RS-485 bus. Failure to do so will compromise the proper operation of the communication channel!Communication wiringTB2TB3TXD RXD RTS CTS GNDTR+ TR- GNDPort 1, RS-232 To Host (Wire with 24 AWG stranded)To Downstream Devices (Wire with 24 AWG, stranded twisted pair(s) with an overall shield)146 — revision 6Hardware Installation Guide29.3Reader WiringEach reader port supports wiegand, magnetic stripe, and 2-wire RS-485 electrical interfaces. Voltage at the reader port (VO) is passed-through from the input voltage of the controller (TB1-VIN) and is current limited to 150mA for each reader port. Readers that require different voltage or have high current requirements should be powered separately. Refer to the reader manufacturer specifications for cabling requirements. In the 2-wire LED mode the Buzzer output in used to drive the second LED. Reader port configuration is set via the host software.DATA1/DATA0 – CLOCK/DATA
