6.7.2 Digital Interconnections (4100-1311 Digital Audio Controller, 4100-1411 ES Net Digital
Audio Controller)
Figure 39 is an illustration of Class X and Class B digital wiring from the 4100-1311 Digital Audio Controller to risers connected to TICs or
the Network Audio Riser Controller Module.
Note: The digital wiring from the 4100-1411 ES Net Digital Audio Controller to risers connected to TICs is identical to the digital wiring from
the 4100-1311 Digital Audio Controller to risers connected to TICs
Note: Old legacy 0566-409 Digital Audio Controller, 0566-407 DARIC, and 0566-833 MCC DARIC boards were replaced due to component
obsolescence. The replacement boards are the 0566-1028 Digital Audio Controller, 0566-1000 DARIC, and 0566-1001 MCC DARIC. They
are functionally equivalent to the legacy boards.
Note:
1. All wiring is 24 AWG to 18 AWG, twisted-pair.
2. Maximum wire distance: 2,500 feet (762 meters) from digital audio controller primary to the digital audio riser card.
3. Maximum distance between subsequent nodes: 2,500 feet (762 meters)
4. Maximum line distance and capacitance between nodes:
- 18 AWG : 40 Ohms maximum, 0.055 µF maximum
- 24 AWG: 135 Ohms maximum, 0.055 µF maximum
5. All wiring that leaves the building requires the 2081-9044 Overvoltage Protector at each entry or exit to the building. A maximum
