Connection Through M12 Bottom
Connector or Screw Terminal
Checking/changing the device settings can also be made through the
M12 bottom connector or screw terminal. Then you have to have know
the communication settings of the device, 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 factory defaults settings are
as follows:
NOTE Changes in the serial interface/communication protocol/baud settings
take place when disconnecting the service cable or when resetting the
sensor.
If these settings are not changed during the service connection session,
original main port settings (at M12 and screw terminals) are returned,
as soon as the service cable is disconnected from either end.
