HelixNet: HMS-4X main station connections to Tempest via 4W or 2W
Tempest to HelixNet via 4-wire (note no software re-pining on 4W ports) so use audio x-over CAT-5/6 cable.
Tempest to HelixNet via 2-wire
Note that you need to use a Clear-Com PL power supply / Main Station or put Tempest 2W ports into “Master Mode”
which sets termination and +24Vdc on 2W XLRs.
