Setting configuration switches

DIP switches

The DIP (dual inline package) switches on the rear panel of the interface control the sync on green output, Digital Display Sync Processing, and serration pulses. The DIP switches on the front of the RGB 109xi provide ID bit termination. Set DIP switches to either On (Closed) or Off

1	2	3	4	(Open) to select the desired function as
				described in the sections on front and rear
				panel features on pages 2-2 through 2-5.

CPU dial switch (RGB 112xi only)

The CPU dial switch specifies the type of computer to which the interface is attached. To change the switch setting, insert a small screwdriver in the slot in the center of the dial, and turn the dial to the desired position.

Mounting the interface

To mount the interface under a desk or in a podium using the under desk mounting kit (Extron part number

70-077-01), do the following:

1.Attach the mounting brackets to the interface using six machine screws supplied with the mounting kit (see figure 9).

Figure 9 — Attaching the under desk brackets (part number 70-077-01)

2.Using the to-scale template on page B-3 to guide you, mark the four screw holes on the underside of the surface to which you are mounting the interface.

3.Drill four pilot holes, each 3/32” in diameter by 1/4”

deep, where marked on the template.
