CONNECTING TO THE PC (IC500 Serial Port)

The IC500 controller Communicate to the PC via a Serial port The serial port on the controller can be config-

ured to use either the RS232 or RS485 protocols. If the controller has to be connected to a PC at less than 30

meters either the RS232 port or the RS485 port may be used. If the distance is greater than 30 meters or if

several controllers must be connected together the RS485 port should be used.

CONNECTING THE LOCK

The Door Output on the controller can support a maximum of 24V/1A. - If the release mechanism has a

charge that exceeds this limit or has a strong inductive charge (as in the case, for example, of revolving doors

or turnstiles) then it will be necessary to use an intermediate relay between the controller and the Door.

Sensor recommend any 18AWG, 2 conductor cable

The three signals - 0v, Rx and Tx - are connected to a serial plug in the PC as follows:

25 Pin Plug (PC) 9 Pin Plug (PC) IC1000+ J3

Pin 7 (0v) Pin 5 (0v) 0v

Pin 2 (Transmit) Pin 3 (Transmit) Rx/L

Pin 3 (Receive) Pin 2 (Receive) Tx/H

In nearly all cases RS485 connection will take place via an RS485/USB interface, however in the

rare situations where an RS485/RS232 interface is to be used, the interface should be wired to

the PC according to the details above.

To connect via an RS485/USB interface, simply plug the USB connector into a port, and wire as

follows:
