3DIP Switch — Controls sync on green output, Digital Display Sync Processing, and serration pulse removal.

1 — SOG (sync on green output)

5RGB output —Connect coaxial cables to these female BNC connectors to an RGB ourput device. Connect cables for the appropriate signal type, as shown below.

On — If this switch is set to On (up), the interface outputs sync on green.

Off — If this switch is set to Off (down), output is RGBS or RGBHV, depending on how the interface and projector are cabled.

6	Audio output connector — One 5-conductor, 3.5-mm captive
	screw terminal for audio output. See page 2-13 for audio
	connection details.

2 — DDSP (Digital Display Sync Processing)

On — If this switch is set to On (up), the interface does not perform sync processing. This may be necessary for digital display devices, such as LCD, DLP, and plasma displays.

Off — If this switch is set to Off (down), the interface performs sync processing operations, such as horizontal shift, using Extron’s ADSP.

Turning on the DDSP feature disables the horizontal shift control.

3 — SERR (serration pulses)

Many display devices, such as LCD and DLP projectors and plasma displays, must have serration pulses removed from the sync signal in order to display images properly. Flagging or bending at the top of the video image is a sign that the serration pulses should be removed.

On — If this switch is set to On, serration pulses are present on the output signal.

Off — If this switch is set to Off, serration pulses are not present on the output signal.

4 — SPARE — No function is assigned.

4CPU dial switch (RGB 112xi only) — Use a Tweeker or a small screwdriver to set this switch to the type of

computer attached to the RGB 112xi interface (IBM, Sun, or SGI), or if the computer produces sync on green only, set the switch to SOG.

Installation

Overview

The installation procedure is the same for the RGB 109xi and the RGB 112xi, except that each interface attaches to a different type of computer. See “Cabling” on page 2-11 for more information.

To install and set up the RGB 109xi or the RGB 112xi for operation, perform the following basic steps (the remainder of this chapter provides detailed steps):

1Turn off power to the computer or workstation and its monitor, and unplug the power cable from each of these devices. Turn off power to the projector, and unplug its power cord.

2Disconnect the monitor signal cable from the computer. If speakers are attached to the computer’s sound card, disconnect them as well.

3If desired, change the configuration of jumper J20 (sync polarity) or J40 (vertical sync width). See “Setting internal jumpers” on page 2-6.

4Set the DIP switches ID bit configuration (SOG, DDSP, SERR). See "Rear panel features" on page 2-3.

5If desired, attach the interface to a table or under a podium using an optional Extron mounting kit. See “Mounting the interface” on page 2-9.

6Attach the interface to the computer, attach the local monitor, if used, to the interface, and attach the projector to the interface. See “Cabling” on page 2-11.

If you are not using a local monitor with the RGB 112xi, you must attach an MFTA (multi-frequency termination adapter) to simulate a monitor.
