3.4 Daisy Chaining Audio and Computer Signal Between Modules

Distances up to 2 ft / 0.6 m are for connecting multiple modules in a single cluster while distances over 2 ft / 0.6 m are for connecting physically distributed clusters.

Up to 1 ft / 0.3 m: Supplied Cat-5 Signal Link Cable

Connect between Signal Link jacks (Neutrik® EtherCon®) on vertically adjacent modules within a multi-module cluster.

Up to 2 ft / 0.6 m: User-supplied, Cat-5 Ethernet crossover cable Connect between Signal Link jacks (Neutrik® EtherCon®) on horizontally adjacent modules within a multi-module cluster.

3.5.1 AC MAINS SUPPLY

Provide the module with a 50 Hz or 60 Hz ac mains circuit capable of:

	100 V to 120 V	220 V to 240 V
DSA230i and DSA250i	4 A	4 A

Figure 3.4b Signal Links >2 ft / 0.6 m

Before applying power, ensure that the ac mains voltage matches the voltage rating on the module.

DANGER: DO NOT APPLY 230 V MAINS POWER IF THE VOLTAGE RAT-

ING ON THE MODULE IS 115 V. IMMEDIATE AND CATASTROPHIC

DAMAGE TO THE MODULE WILL RESULT AND MAY CAUSE A FIRE

HAZARD, SERIOUS PERSONAL INJURY, OR DEATH.

3.5.2 AC MAINS CABLE

Supply and connect #14 AWG / 2.5 mm power cable and appropriate ac

mains plug to the supplied Neutrik/PowerCon® connector. Figure 3.5 Connecting AC Mains
