See fi gure 2-7 to properly wire an output connector for the mono audio BME.

0.2” (5 mm) max.

Do not tin the wires!

Figure 2-7 — Captive screw connector wiring for mono audio output

N The length of exposed wires is critical. The ideal length is 0.2” (5 mm).

• If the stripped section of wire is longer than 0.2”, the exposed wires may

touch, causing a short circuit between them.

• If the stripped section of wire is shorter than 0.2”, wires can be easily pulled

out even if tightly fastened by the captive screws.

The volume level for each output can be individually set via the front panel
or Ether net or RS-232/RS-422 control. See chapter 3, Operation, chapter 4,
SIS Programming and Control, chapter 5, Matrix Software, and chapter 6,
HTML Operation for details.

N BME 0 should house the front panel controller and be the BME used for system

control and monitoring via the serial ports and Ethernet LAN link.

f

BME address switch — Each BME must be set to a unique address of 0

through 5.

numbers.

Sync BMEs cannot be set to address 0.
