Connection cables
The connection cable options for WMT52 are listed in the table below.
The USB cables allow the sensor to be connected to a PC using a
standard USB port. The USB cables also provide operation power to the
sensor when connected. Note that the USB cables do not provide power
to the heating.
NOTE The RS-485 and RS-422 interfaces cannot be directly accessed with a
standard PC terminal. They require a suitable converter. For accessing
the RS-485 interface, you can use the USB RS-232/RS-485 Cable; see
section
Connection cables on page 52 .
NOTE RS-232 and SDI-12 can be accessed with a standard PC terminal,
presuming that, for SDI-12, the Data in/out lines have not been
combined inside WMT52.
