I have an experiment that was running fine until the power was turned off. When the system came back up I could no longer talk to my instruments. Communication is via a PCI-GPIB board. I can write command to the instrument and it accepts it fine, however it will not accept a second command or reply to the first command. I believe the instrument if not being terminated correctly. The instrument requires a carriage return and line feed with EOI asserted with the line feed. It also requires REN to be asserted with every command. I can read the bytes received from the GPIB card and the instrument never receives a line feed. I can set it to use a line feed as the EOS in the Properties of the PCI-GPIB card, but when I use the "communicate with instrument" function it always disable the line feed after every execution. The instrument never sees the line feed. I read some of the help items were it discussed using DEvice Templates, but I cannot find them on my machine. It is not clear whether setting the EOS character line feed replaces the standard carriage return or is appended to the carriage return.
