5.1.2 AUDIO SIGNAL CONNECTION
See Appendix 8.6 for details about multiple module wiring
configurations.
CobraNet: Skip to Section 5.2 if using CobraNet for
distribution of the audio and control signals.
Audio A 2-conductor twisted pair, shielded, audio cable
or connected to supplied 3-pin Phoenix Contact Terminal
Audio B: Plug and to the line level audio signal source.
Nominal level: 0 dBu / 0.775 V rms.
Recommended Conductor Gauge:
24 AWG to 18 AWG / 0.2 mm to 1 mm
Audio A
and
Audio B:
As above but 4-conductor twisted pairs
5.1.3 COMPUTER CONTROL CONNECTION
CobraNet: Skip to Section 5.2 if using CobraNet for
distribution of the audio and control signals.
EIA-485 2-conductor twisted pair, shielded, cable connected
(formerly to supplied 3-pin Phoenix Contact Terminal Plug
RS-485): and to EIA-485 port for the computer.
Recommended Conductor Gauge:
24 AWG to 18 AWG / 0.2 mm to 1 mm
NOTES:
1. Do not combine EIA-485 and audio signals in the same cable.
2. An EIA-485 converter is required to convert a PC’s RS-232 or USB
port to a 2-wire EIA-485 port. While there are many converter
products available, contact EAW’s Application Support Group (See
Section 7.3) for recommendations about suitable models.
3. EIA-485 cabling has special requirements and limitations. See
Appendix 8.3 for details.
5.1.4 DAISY CHAINING COMPUTER AND AUDIO SIGNALS WITHIN
CLUSTERS WITH MULTIPLE MODULES
NOTE: The Signal Link jacks carry both computer and audio signals.
The cable between the Signal Link jacks must be wired as a standard
Ethernet crossover cable. A cable wired as a standard Ethernet
straight through cable will not work.
1. Up to 1 ft / 0.3 m between adjacent over/under modules in a
cluster:
Supplied Cat-5 Signal Link Cable
Connect between unused Signal Link jacks (Neutrik EtherCon) on
vertically adjacent ends of the modules.
