Connection Cables
The table below shows the connection cable options for the WXT530
series transmitters. The USB cables connect the transmitter to a PC
using a standard USB port. The USB cables also provide operation
power to the transmitter when connected. Note that the USB cables do
not provide power to the sensor heating.
NOTE
The RS-485 and RS-422 interfaces cannot be directly accessed with a
standard PC terminal. They require a suitable converter. To access the
RS-485 interface, use the USB RS-232/RS-485 Cable. See
Connection
Cables on page 74 .
NOTE
RS-232 and SDI-12 can be accessed with a standard PC terminal, if for
SDI-12, the Data in/out lines have not been combined inside the
transmitter.
