TECA Cold/Hot plate: AHP1200CAS

[boyapati]

Hello all,

I am using the TECA Cold/Hot plate: AHP1200CAS to be able to set temperature for testing a UUT.

The Labview VIs for reading and setting temperature: PV Read and SV set do not result in a response.

When a read operation is performed after either the PV Read or SV set write operation is performed, nothing comes out of the controller.

No error is generated from the read operation.

The ATEC software GUI whch comes with the instrument works.

Anybody has any experience with this instrument?

Thanks,

Vikram

Link the LabVIEW driver VIs, or attach it in a zip, so we can have a look. I guess you connected the device to your PC using an RS232 cable? Do you have a manual? Did you check pinout of the RS232 interface? Often devices require cross-linked serial cable in order to communicate... It might be you use a simple straight serial cable, this is a common mistake...

Thanks. I had to set the baud rate to 19600 in Labview to get it to work. The example VI did not have it set.
