Virtual COM Application

The tDS-700 series is designed to link RS-232/422/485 devices to an Ethernet network. The

VxComm utility allows the built-in tDS-700 COM Port to be virtualized to a standard COM Port of a

host PC, as shown below:

In the configuration above, Meter-1 is virtualized to link to COM3 of the host PC. Therefore, a

program originally designed for the MS-COMM standard can access the meter without the need for
any modification.
