Looking for feedback from anyone who has used the HW-TVMKIT-120 and TVM2's. I have a situation where I need to use a TVM2 in slot 11 with no TVM2's in slots 1-10.
I am curious to know exactly how the addressing works between QS and the TVM-Kit. For example can I place the TVM2 in slot 1 of the TVMKIT and use the phoenix connector of the harness for TVM2 11 or do I absolutely have to place the TVM2 into the 11th slot?
Subsequently will this cause any problems if there are no TVM2's landed until the 11 slot? Do they need to start at 1? I called tech support and they said it should not be an issue but wanted to see if anyone had any real world experience in a layout like this.
The tvm address is determined by what plug on the harness you plug it into the harness is labeled with the numbers. Keep in mind that once you assign a load to that tvm the corrasponding rpm zone can not be used for anything but that tvm load. For example a tvm in tvm 2 on the harness will use rpm 1 outputs 3 and 4 If no load is assigned to the tvm then that output is still available on the rpm. Once you assign a 0-10 load to rpm 1 output 3 not only will the tvm send 0-10 but the rpm 1 output 2 will switch on and off
So are you saying the only "addressing" that takes place is at the harness itself and not a combination of the slot and the harness? Have you done this in the field? I just want to verify as tech support is unable to say with 100% certainty.
I understand the RPM outputs and how they match up. We have done TVM2's on a few jobs but we have always started at the first slot and subsequently first RPM output so this has never come up.

I just looked at a harness and the addressing is done via jumpers on the harness depending how the jumpers are set up on each plug of the harness i would say determines the address
