Can I replace a CPM-1 with a CPM-3 in my SNV-12 Voter?

When replacing a CPM-1 with a CPM-3 in an SNV-12, be aware of what version of firmware you need.

If using SVM-2 or SVM-3 (no IP backhaul) modules, you should be using firmware version 1.08.

If using SVM-3 modules for IP backhaul (with QMT-1B's), you must be using firmware version 3.00.
