DAC-NET Class X (ULC DCLC) D-NET Wiring
Each connection between two nodes has to be installed in separate cable
routes.
All CAN cards and modules must be combined via CAN Bus. The CAN Bus
requires a 120 Ohm termination resistor on both ends. Use a CAN terminator
at CAN connectors and a termination resistor at screw terminals to fulfill it.
They are shipped with DAC-NET. See Figures 9-14.
All digital audio cards and modules must be connected via the ASI-Bus (LPB,
AIC, ZAC-40, ZAM-180, XDMC). The ASI-Bus consists of 4 pairs (Part of CC-
5). They require four 120 Ohm termination resistors on both ends. Use an ASI
terminator at 60-pin connectors to fulfill it. They are shipped with DAC-NET.
See Figures 9-14. The PMI/PMI-2/PMI-3 provides ASI termination at one end
when used.
The Analog Audio Bus includes three audio signals with a level of
0dBu/+6dBu (LVM microphone, LVM monitor speaker, FMT Phone). The LPB
supervises the microphone signal wiring. The supervision requires an EOL
resistor 3.3K. The EOL resistor is integrated in the LVM.
If one LVM is mounted, the jumper P7 must be set in position 1 – 2.
LVM default factory setting: Jumper P7 in position 1 – 2
