Hi, We have an USB-TC, bought from Omega labeled OM-USB-TC. Problem is I cannot see the analog or temperature inputs of the USB-TC in Labview with ULx. We also have a OM-USB-1608FS-PLUS connected. PN : 193816F-03L SN : 1CE3918 Instalcal config : DEV0 = USB-1608, DEV1 = USB-TC Windows 11 Labview version 20.0.1f1 (64 bit) I tested the USB-TC in instacal and I can see the temperature of a thermocouple in channel 0 (image 4). You can also see the USB-1608 and board numbers. For AI Voltage, I can see the USB-1608 inputs only (image 1). For AI Temperature, I see no inputs (image 2). For Digital input, I see the inputs from both devices, USB-1608 and USB-TC (image 3). I can read the digital data from the USB-TC, I ran the exemple ‘ULx Read Dig Chan’ and I see the input changing when I test it (image 5). Thank you, EDIT : Follow-up. I tried changing the USB connections to see if it had an impact and now it works! I don't understand why but this is what I did : 1. Unplug the 1608 and connected the USB-TC in it's place. Relaunch Instacall and it removed the 1608. Now I had the TC inputs in Labview in AI Temperature! 2. Unplug the USB-TC and reconnected it where it was at first, when it did not show the inputs. Still working. 3. Reconnected the 1608 where it was at first, so everything is like when I posted. Relaunch Instacall to add the 1608 back. Still works, strange.

Okay thank you for the fast answer.

Hi, Using USB-1608FS-PLUS with Labview ULx driver. Is there a a way with the Labview drivers to get the current states of the digital outputs? When the program stops, the output keeps their last states, so I would like a way to be certain of the current output states when the program starts. I know I could just reset them all on program start but I would prefer to have the option to keep them as they are if needed. Thank you,
