● Normal communication is not guaranteed when using USB connector as a communication port in ordinary times. ● In case of RS-485 cable (2wire) connection, connect only both SDA and SDB lines. ● The RS-485 of the Xpanel runs under auto toggle mode. ● To reduce the risk of damaging the RS-422 circuit, be sure to connect the Pin 5(SG) terminal. |
