4 Engineering - Channel Layout
There are certain rules that you should be aware of when planning the channel layout in the VC-8000
rack. These are explained below.
4.1 Phase Trigger Channels
The VC-8000 rack allows for six Phase Trigger channels maximum (16P rack). Phase Trigger
channels can only be selected in channel 4 of a UMM installed in slots 4-9.

4.2 Orbit (XY) Pairs
If your rack will be providing CMS data (like orbit, or shaft centerline), all XY pairs need to be in
channels 1 & 2 (or channels 3 & 4) of the same UMM.
