Hi this topic has been covered on here before a few years ago and i am a labview beginner and looking for a helping hand in the right direction
I am trying to control a Thermotron 7800 controller using a USB/Serial interface cable with a Labview program.
To try establish if i am connecting to the controller i am using in measurement and automation explorer and devices and interfaces it recognises the USB/Serial connection as ASRL46:INSTR "COM46"
All the setting's match with the controllers setting but when i go to read or write in the I/O section, it just returns errors.
I have been told to cross pins 2 & 3 on the serial interface.
Has anyone worked on a similar project as this?
Also I have downloaded the relevant drivers from Thermotron.
Is there a list of what the commands are on the I/O section on the test panel?
