I have been tasked to replace old Black Box GPIB-RS232 converter boxes with NI boxes. But, there are configuration settings in the old Black Box that I am not sure can be replicated with the NI box. We are trying to make this work in "D Mode".
Making the GPIB-RS232 converter "data transparent" is one that is causing difficulties transmitting for GPIB to serial to our DUT. The DUT already required us to use a 25ms delay in between each byte transmission even with the old Black Box. However, the NI replacement box requires us to use 100ms delay in between each byte transmitted serially. It appears that the NI box is grouping all of the bytes in it's buffer and transmitting them without the required 25ms delay between each byte unless we increase the delay to 100ms or longer.
Maybe there is a timeout setting or wait setting I need to use in "G Mode"?
