The UT320 and UT340 instruments are normally controlled through their Windows based user interface, or by controls embedded within an NDT software platform, such as Winspect or InspectionWare.

These instruments can also be controlled remotely by simple ASCII commands, communicated through a standard RS232 serial port.

Most programming languages and graphical application platforms support COM ports and the RS232 protocol. Hardware drivers are not required to control the instrument with your own software.

Using the COM Port

The COM port configuration expected by the UT320 or UT340 is:

Baud Rate = 19200, Parity = None, Data Bits = 8, Stop Bits = 1.

Flow control is not necessary if the commands are paced so that the instrument has time to execute them.

Hardware handshaking mode is also possible, in which case the host computer must use the CTS and RTS lines to control the data flow.

Once serial communications are established, the instrument will respond to ASCII commands.

For example: PV100 sets pulse to 100V, PW40 sets the pulse width to 40 ns

Multiple commands may be sent simultaneously, delimited by semicolons or spaces, and the instrument will configure itself accordingly.
