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

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.
