NI-Communicator truncates string length

[Marv Wagner]

When using NI-Communicator to send commands to a particular instrument, we have discovered that the NI-Communicator is limiting the length of the string sent to the instrument to 99 characters. This can be observed by using NI-Spy. The same NI-488.2 drivers can be used from another custom program to send much longer strings.

The user interface to NI-Communicator should be fixed to limit input strings to the same length or this limitation should be fixed.

Hello Marv,
The NI-488.2 Communicator is primarily for troubleshooting purposes, which is why it only shows a limited number of characters. GPIB communication is usually done through a program because the responses also need to be parsed and processed. I will, however, submit your request to R&D to have that length re-evaluated.

A limited number of characters is fine. The input box shouldn't let you enter more than the application is really sending, however. Otherwise, the whole purpose of using NI-Communicator to troubleshoot is twarted by it's use confusing things even worse.

My apologies, I misinterpreted your suggestion. I thought you were referring to number of characters displayed by the communicator when it shows a response. I will submit another Corrective Action Request.
