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.
