How do I send commands to Analyser serially using GPIB-232CT-A?

[Thabiso]

Hi

I am using the GPIB-232CT-A to send commands to a network analyser using the serial coms commands and I am having the following problems:
1) Network analyser only responds to the command only if I reset the analyser.
2) I cannot send more than 2 commands. The analyser only responds to the first command.

Do you know which commands I must use to send more than one command without having to reset the analyser everytime I need to send the command.
The command that I use is 'wrt ' .

Thanks in advance.

maybe you could give the manufacturer and type of the analyzer

Hi Albert

The analyser that I am using is the HP8753B and I think the commands are compatible with the HP8510C.

Thanks

Sounds like you might not be sending the termination character that the analyzer expects.  Check the manual for the analyzer to see what termination character it wants via the serial port.  Make sure you're sending this.  Doublecheck by running the serial cable into a (another or the same) computer and viewing the incoming data with hyperterminal or NI-VISA.

NI spy also works great in finding out what happens on the serial line.

You have it installed with the drivers

I have send the termination character and there is still no changes. Is there anything I need to do before I use the command 'wrt'?

Thanks

Hi,

suggestion: squeeze the NI board and use the RS-232 board directly then
when everything works fine go back to NI solution ...
