2.5.5 RS485 Digital Control Port Connection to Other SP4-APS

Splitters

Connect the RS485 OUT on the SP40/2 SP4-APS splitter to the RS485 IN on the next SP4-

APS splitter connected to an audio booster (SPB-80/4, SPB-160, SPB-320). Observe proper

polarity.

NOTE: Refer to Section 1.1, Figures 1 and 2 on Pages 6 and 7. These figures show the order of the

connections of the splitters.

2.6 Wiring Diagrams

2.6.1 Wiring Connections for SP4-TZC to SP40/2 and an SP4-APS

Appendix B in the back of this manual shows the typical wiring diagram to wire the SP4-TZC to the

SP40/2 with one SP4-APS.

2.6.2 SP4-TZC to SP40/2 with an SP4-APS and Audio Boosters

with Multiple SP4-APS Splitters

SPB-160

Appendix C in the back of this manual shows the typical wiring diagram to wire the SP4-TZC to the

SP40/2 with one SP4-APS splitter and an Audio Booster with multiple SP4-APS splitters. The diagram

uses an SPB-160 Audio Booster because it has two Audio Outputs with a splitter on each.

SPB-80/4

The SPB-80/4 Audio Booster has the same audio terminals except that it has a single audio output. Use

Appendix C and follow the same wiring sequence as the SPB-160 wiring a single SP4-APS.

2.6.3 SP4-TZC with the SP40/2, Multiple SPB-160s and Multiple

SP4-APS Splitters

Appendix D in the back of this manual shows the proper wiring of the SP4-TZC connected to an SP40/2

and two SPB-160s with multiple SP4-APS splitters.

SPB-320

Appendix D in the back of this manual also shows the proper wiring of the SP4-TZC connected to an

SP40/2 and the two SPB-160s with multiple SP4-APS splitters located in the SPB-320 enclosure.
