of the audio and control signals.

EIA-485 (formerly

RS-485): 2-conductor twisted pair, shielded, cable connected to supplied 3-pin Phoenix Contact Terminal Plug 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 LOUDSPEAKERS

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.
