High Voltage Supplies / Questions and Answers

We wanted to control the NHQ105M unit through RS232 using computer. We have tried to do the same using HyperTerminal of windows. We were able to get the echo but all the commands in the table of the manual did not work?

It's not so easy to communicate via RS232, the timing of sending commands is a bit critical. See the following part in the manual:
The data exchange is character based, synchronisation between the computer and the supply (input) is performed using echo. The data transfer to the computer (output) is asynchronous, breaks between two characters, programmable of the break time, allow the computer to receive and evaluate the incoming data. Break time is setting 3 ms at works.

We offer a Windows software for controlling the NHQ105M via RS232, see
