I am trying to help out a client who has a faulty York LDC 34 controller. It controls a HVAC installation via York TDC9 outstations which operate ventilation controls. Does anyone have experience in controlling the York TDC9 outstations using DAQFactory?

In a quick search I couldn't find an info on the TDC9's. The LDC34 I found a little. Its got an ASCII protocol that with a little time one might be able to figure out (the docs are, like many, a bit over detailed with no examples). If you can figure out the docs, you almost certainly can then communicate from DAQFactory.
