3.7 Serial Communication
In WMT700, there are two serial communication ports:
• COM1: Service port (RS-485)
• COM2: Configurable digital communication interface
Both ports support the same commands, protocols, operations, and data messages. You can
use any computer or data logger with a serial port to send commands to WMT700 and to
receive measurement data.
3.7.1 Communication Interface
COM1 is a fixed RS-485 communication interface to be used as a service port.
COM2 is a flexible digital communication interface that is preconfigured according to your
order. The available options are:
• RS-232 (recommended up to 15 meter distance)
• RS-485 (recommended up to 1200 meter distance in point-to-point connection)
• RS-422 (recommended up to 1200 meter distance)
• SDI-12 (recommended up to 60 meter distance)
Note that the recommendations depend on communication speed and cable type. In
optimized environments even longer distances can be considered.
Regardless of the factory configuration, you can change the COM2 interface type by using
terminal software.
