GPIB-232CT-A serial protocol

[marlanbrando]

Pertaining to the programming of the GPIB-RS232 controller, our end RS232 device is not a Windows nor linux based so no NI drivers can be installed. The RS232 device will only be a listener or listener, never a controller. So it seems like either G mode or D mode would be what we can use it under with D mode sounding like what we should use. What we can't determine from the online documentation is how, without installed drivers, would the RS-232 device instruct (C Programming) the GPIB-RS232 to activate the SRQ line. We want to be able to control that.

marlanbrando,

The GPIB-Serial Converter acts only as a device that converts GPIB commands to Serial commands.  Your program on the controlling end will have the ability assert and deassert the SRQ line.  The GPIB-Serial Converter is only a converter.  The only software you will need to use is the installation CD that comes with the GPIB-Serial Converter.

Does NI-Spy work with GPIB-232CT-A?  It doesn't appear so.  We need to capture the call traffics but have been unable to.  Is there something available?

With the new GPIB-RS232 operating in GPIB-232CT-A compatible mode, does it require device drivers or does GPIB-RS232 acts as proxy still like the GPIB-232CT-A?

With the new GPIB-RS232 device operating in GPIB-232CT-A compatible mode, will NI-Spy work?

Thanks.

marlanbrando,

Based upon you original post for setup # 2:

Windows XP machine <--- serial port ---> NI's GPIB-232CT-A   <----- GPIB ---->  { item B } <serial> <----> custom software 

NI-Spy will pick up the serial commands between Windows XP machine and GPIB-232CT-A.  The reason is because the converter takes commands and then performs those actions on the bus.  This being the case, you would not expect to see the GPIB commands.
