Low Voltage Control: Dry contact RJ11 data cable wiring troubleshooting exclusive method for curtain motor

Dry Contact ControlDry contacts are used to transmit signals without transmitting power and are typically used to trigger other devices or to perform control operations. In our company, dry contact control also is used in our curtain motor and roller blind motor (tubular motor), you can check here.

It is one of the Low voltage control way, also is the wired control way. It requires a data cable to transmit the signal.

RJ11: 4 Pin. Registered jack (RJ) is a standardized telecommunication network interface.
