Tyracont VD14-4 channel controller for vacuum transducers

[chispi23]

Hello,

I am trying to connect to a Thyracont VD14 4-channel vacuum controller (VCL Smartline), but I’m not getting any response from the device when running my LabVIEW VI (attached).

Could you please advise what might be wrong?

Thank you,
Chispi
