Connecting through M12 bottom connector or screw terminal - WXT530

You can check and change the device settings through the 8-pin M12 bottom connector or screw terminal.

To do this, you must know the device communication settings, have a suitable cable between the device and the host, and, if needed, use a converter (for example, RS-485/422 to RS-232, if the host is a PC). The following table shows the factory default settings:
