Someone's gotto know how to accomplish this. I'm beating my head against a brick wall waiting for replies from Compair (US & Canada - even tried South Africa). Everyone I speak to seems to "know" this is possible, and promises to get back to me with the info, but never does. Frustrating.
Basically, the L45SR compressors I have are networkable on a Modbus RTU network. My problem is that I have no idea where to connect the twisted pair (I'm guessing it's at the 3-pin Phoenix connector at the back of the Delcos 3100 controller). Of course, I'm not overly eager to just blindly connect the cable and give it a try.
My second problem is that, even if I figure out how to physically connect the controllers to the network, I have no way to configure each with a unique slave address or to determine what memory address serves what function.
A bit of guidance would be appreciated!
