- If RD is set as "1", the door opens only when the card is read at Reader 1 but not at
Reader2. If it is read at Reader 2, "ACCESS DOOR ERROR" message shows up.
- If RD is set as "2", only when the card is read at reader 2, the door opens but not at
reader1. If it is read at reader 1, "ACCESS DOOR ERROR" message shows up.
- If RD is set as "3", reader 1 & 2 both open each door.
3. Use software for time schedule setting in case it is connected to a PC, shown as in
the software manual.
4. If the trouble remains after checking the above, contact a designated service center.
☞ The controller does not communicate with the Host-PC.
A defective cable is used, errors in wiring, an error in setting COMM ID of the controller,

or damage on the COMM port (either on the PC or on the controller side).
1. Please check the settings of the application S/W and the controller.
- Check if 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 if the baud rate (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 following:
Parity bit
Data bit
Stop bit

3. In case of setting RS422 communication, we recommend to use line-end resistors
of 120 Ohm between the RX (+) and RX (-) lines and between the TX(+) and TX(-
) lines. Apply the same resistors to the converter RS422 lines. Consult a service
center or an electric technician if you are not sure how to do it.
4. When a multi-drop communication doesn't work, test 1-to-1 communication first.
