Reader Connection
Using the recommended cables, splice the cable together with the pigtail of the reader and seal the splice. Route
the cable from the reader to the host module. Connect the cable to the module port according to the required
operation, as shown in the connection diagrams that follow.
The recommended cable types for RS-485 are:
⦁
Belden 9842 or equivalent
⦁
24 AWG twisted pair with characteristic impedance of 120ohm
The recommended cable types for Wiegand are:
⦁
22 AWG alpha 5196, 5198, 18 AWG alpha 5386, 5388
Warning:
The reader outputs D0 (green wire) and D1 (white wire) can switch to a maximum capacity of 50mA.
Exceeding this amount will damage the output.
Shield Connection
Connect the reader and cable shield wires together at the reader pigtail splice. Connect the cable shield to a
suitable earth point.
Do not
connect the cable shield to a ground or AUX connection.
Do not
terminate the reader
shield wire inside the reader.
Important:
⦁
The card reader must be connected to the module port using a shielded cable.
⦁
The shield must only be connected at one end of the cable in the metallic enclosure (frame grounded).
⦁
Do not connect the cable shield to an AUX-, 0V or V- connection on the module.
⦁
Do not connect the cable shield to any shield used for isolated communication.
⦁
The reader and cable shield wires must be joined at the reader pigtail splice.
⦁
Do not join the shield and black wires at the reading device.
⦁
Do not terminate the reader shield wire inside the reader.
