2.4 - Wiring a Satellite Panel
The Millennium System Master is capable of driving up to 64 Satel-
lite Panels. Connect the System Masters together as described here
(See Figures 3 and 6).
1. Connect the RS485 wire from +TX/RX (TB8) on the Master
Panel to terminal +TX/RX (TB8) on the Satellite Panel. Connect
the RS485 wire from -TX/RX (TB8) on the Master Panel to -TX/
RX (TB8) on the Satellite Panel.
2. Connect from MAIN OUT (+) (TB10) on the Master Panel to
SYS_AUD (+) (TB13) on the Satellite Panel. Connect from MAIN
OUT (-) (TB10) on the Master Panel to SYS_AUD (-) (TB13) on
the Satellite Panel ending the loop with a 2.2K ohm end-of-line
resistor (Part No. EOL-2.2).
3. Speaker/Amplifiers can be connected to the Satellite Panel as
described in Section 2.5. NOTE: Speaker/Amplifiers connected
to a Satellite Panel are NOT addressable and connections from
+TX/RX and -TX/RX are unnecessary.
