IDTeck – iCON 1 DOOR ACCESS CONTROLLER
☞ The controller does not communicate with PC.
Cause
Defective cable is used, errors in wiring, an error in setting COMM ID of the controller, or
damage on the communication port (either on PC side or on the controller side).
Solution
1. Please, check the settings of the application S/W and the controller.
- Check the controller’s COMM ID is listed on the application S/W.
- Set the different COMM ID when two or more controllers are installed.
- Check the communication speed (9600bps default) is the same as the setting on the S/W.
- Make sure that the PC’s COM port is set correctly on the S/W.
- The parameters at the S/W should be set as follows.
Parity bit: NONE
Data bit: 8bit
Stop bit: 1bit
2. Check the line connection for communication.

3. In case of setting RS422 communication, it is recommended to use line-end resistors of 120
Ohm between the RX (+) and RX (-) lines and between the TX (+) and TX (-) lines, and
apply the same resistors to the converter RS422 lines. Consult a service center or an electric
technician if you cannot be sure how to do it.
4. When a multi-drop communication doesn’t work, test one-by-one communication first.
5. If the trouble remains after the procedure above, contact a designated service center.
