		- If the RD value is set to “1”, the door opens only when READER 1 reads tthe card, and
		does not open when READER 2 reads the card. If the card is presented to READER 2, the
		“ACCESS DOOR ERROR” message will appear.

		does not open when READER 1 reads tthe card. If the card is presented to READER 1,
		the “ACCESS DOOR ERROR” message will appear.
		- If the RD value is set to either “0” or “3”, the door opens when either READER 1 or 2

3)It is recommended to use termination resistors of 120 Ohm between the RTX (+) and RTX (-) wires when you are using the RS-485 communication. Apply the RS-485 converter to the same resistors.

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 the communication one by one in order from the first one.

5)If the trouble persists after following the procedures above, contact a designated service center.
