Installation, cont’d

7Balanced or unbalanced audio output connectors (captive screw audio connector [A] models only) — These 3.5 mm, 5-pole captive screw connectors output the selected unamplified, line level audio. Connect audio devices, such as an audio amplifier or powered speakers to these connectors. See figure 2-6 to properly wire an output connector.

Do not tin the wires!

CAUTION

Connect the sleeve to ground (Gnd). Connecting the sleeve to a negative (-) terminal will damage the audio output circuits.

The length of exposed wires is critical. The ideal length is 3/16” (5 mm).

•If the stripped section of wire is longer than 3/16”, the exposed wires may touch, causing a short circuit between them.

•If the stripped section of wire is shorter than 3/16”, wires can be easily pulled out even if tightly fastened by the captive screws.

8RCA connector audio output (RCA connector audio [A RCA] models only) — The switcher has a pair (left and right) of RCA connectors for each unbalanced stereo audio output (figure 2-5).

Remote connection

9RS-232 connector — Connect a host device, such as a computer or control system, to the switcher via this 9-pin D connector (figure 2-7) for remote control of the switcher.

Figure 2-7 — RS-232 port pin assignment

The cable used to connect the RS-232 port to a computer or control system may need to be modified by removing pins or cutting wires. If you encounter problems while operating under RS-232 control (the switcher may hang up), pins 1, 4, 6, 7, 8, and 9 may need to be disconnected. Either cut the wire to pins 1, 4, and 6 through 9 in a hard-shelled connector or remove pins 1, 4, and 6 through 9 from a molded plug.

See chapter 4, “Remote Operation”, for definitions of the SIS commands and details on how to install and use the control software.
