I am trying to use an Agilent 6812B AC power source with the ACPWR class IVI driver over RS232. I have everything setup in NI Max but I can't get through the initialization routine. I've tried in both LabView and LabWindows and neither will work.
I decided to monitor the RS232 RX/TX lines and I see it is sending the "*IDN?" command and it times out before receiving a response. Unfortunately, it is not sending the line feed terminating character at the end of the string. I can go through NI MAX and send "*IDN?\n" and it replies back with the ID just fine.
So my question is, could it be possible that the IVI specific driver is just not written properly to send a line feed as a terminating character or do I need to setup the comport to send this character seperately? The IVI driver was downloaded from NI's instrumement driver network and it says it is compatible with the 6812B but has been tested with a 6813B.
