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

Tip

0.2” (5 mm) max. Ring

Do not tin the wires! Sleeves

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

NThe 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.

BME connection and selection

NBME 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.

Addresses 6 through 9 are invalid.

The addresses used in the system must be sequential with no skipped numbers.

Sync BMEs cannot be set to address 0.

To set the BME address, press the + and - buttons on the BME Address switch on the rear panel of the switcher (figure 2-8).
