Does anyone have a LabVIEW driver for a Additel ADT761 Automated Pressure Calibrator?
I have been trying to build one but I am having issues trying to communicate over the serial port with it. I can use Additel's app called "Additel/Land" and that talks to it fine. I can also communicate with it using a terminal app called "iCommTool" which Additel suggested. This proves that my USB to RS232 converter is working correctly. I do not have a null modem in the communication line and I assume this is correct as the "Additel/Land" and "iCommTool" apps are working. But I cannot communicate with it using LabVIEW, or an app called "RealTerm" or the "PuTTY" app. One thing that I have noticed is that when I am using "Additel/Land" or "iCommTool" both the "RST" and the "DTR" on my DB9 Pocket Tester remain red while using the other programs (LabVIEW and PuTTY) they turn green as soon as I connect to the serial port. I don't think this means much as the communication to the ADT761 only uses GND (pin 5), TXD (pin 3), and RXD (pin 2) wires.
Any suggestions?
