PrimuX 4S2M and PrimuX xS2M II
The PrimuX 4S2M and PrimuX xS2M II controllers are packaged with cables for connections
to modern PMX boxes. Depending on its mode of operation (TE or NT) simply connect each port
with either a PMX line or a PBX. You can use the same cable for both modes of operation as the
PrimuX controller will switch the signals as needed.
If you have a different setup please make sure that the connections are made according to the
table below:
PrimuX PIN 1 → RX (controller receives)
PrimuX PIN 2 → RX (controller receives)
PrimuX PIN 4 → TX (controller transmits)
PrimuX PIN 5 → TX (controller transmits)
