Hello,
I am working on an old device that communicates in GPIB but with only one PC.
my project is to replace this PC with a new equipment.
Right to the problem:
I need a dll / library in C# to create a manual handshake where there is no need in a response when I am a CIC listener.
The story:
So far we had not much success using GPIB-USB-HS+, until recently.
I have found that the Device communicates with special commands (nothing like "*IDN?", all in special Hex Bytes).
if you send the correct sequence it will not answer you UNLESS!! you start a handshake first(even though you are the controller and the device now a talker), like manually doing handshake.
I achieved a result by using NI Analyzer Handshake Switches(*attached picture*) to create this first HS when I am as a listener and CIC.
I tried using TMS9914 and NAT7210 in TMS9914 mode but it can't find the device on the bus even though the NRFD is Low when it's connected to 9914.(*attached picture*)
Would be very happy for your help,
