Introduction  
Advanced Digital Sync Processing(ADSP) — ADSP  
allows sync processing operations, such as horizontal  
centering, to occur without affecting the signal’s sync  
timing. This allows horizontal centering to be  
applied to signals that are output to digital display  
devices such as LCD projectors, DLP projectors and  
plasma displays. A rear panel DIP switch allows an  
alternative, Digital Display Sync Processing™  
(DDSP), to be used instead.  
About This Manual  
This manual contains information about the RGB 138xi and  
RGB 158xi universal analog interfaces and on how to  
operate and configure them. Unless otherwise specified,  
references to “the interface” refer to the features or  
operation of both models.  
About the RGB 138xi and RGB 158xi  
The RGB 138xi and RGB 158xi are computer-video and  
stereo audio interfaces with 300 MHz (-3dB) video  
bandwidth. These interfaces have a horizontal frequency  
range of 15 kHz to 125 kHz, so they can be used with any  
type of analog computer signal, including those from VGA,  
SVGA, XGA, SXGA, XGA-2, Mac, Quadra, Sun, and SGI  
computers.  
Gain/peaking control To compensate for signal  
degradation caused by long cable lengths, use this  
rear panel toggle switch to increase output voltages.  
Serration pulse — This feature allows serration pulses to  
either be present or not present at the output.  
Serration pulses are required for some displays.  
Pass-through connectors — A wide assortment  
of architectural adapter plates is available for  
installation on these interfaces to allow convenient  
pass-through A/V connections.

vertical centering with a front panel knob.  
75 ohm video termination — 75 ohm video termination  
can be selected from a rear panel DIP switch.  
Furniture and rack mountability — The RGB 138xi and  
RGB 158xi can be mounted under a desk or podium  
with optional hardware, or they can be mounted in a  
rack or through a desk or other furniture with  
included vertical mounting brackets.  
RGB 158xi features  
Buffered local monitor output — A 15-pin HD female  
connector provides a front panel buffered output for  
a local monitor.  
Active stereo audio — Unbalanced stereo audio input via a  
front panel jack is output as balanced, line level  
stereo audio on the rear panel captive screw  
connector.  
ID bit termination Two front panel DIP switches  
provide ID bit termination on pins 4 and/or 11 of the  
local monitor output.  
Horizontal shift control — Both models feature front panel  
horizontal centering control.  
Sync stripping — Incoming sync will be stripped from the  
red, green and blue signals.

2 — DDSP™ (Digital Display Sync Processing™)  
This feature may be necessary for digital display  
devices such as LCD (liquid crystal display),  
DLP (digital light processing) and plasma  
displays. Use this option if the image still is not  
displayed properly after all other options, such  
as serration pulse removal and video  
3-position gain/peaking switch — Use this toggle  
switch to compensate for signal degradation caused  
by long (over about 125 feet) cable lengths. Choose  
the setting that provides the best image on the output  
display device. Select from these options:  
termination changes, have been explored.  
Unity (no gain or peaking) — The output level is  
the same as that of the input and with no  
added peaking.  
ON — When this switch is set to On, the  
interface uses Digital Display Sync  
Processing instead of Advanced Digital  
Sync Processing. DDSP does not  
process the sync signal.  
50% — This setting increases the output signal  
level and adds 50% of the maximum peaking  
to the signal.  
DDSP will disable horizontal and vertical  
shift controls.  
100% — This setting increases the output signal  
level and adds 100% of the maximum peaking  
to the signal.  
OFF — When this switch is set to Off, the  
interface performs sync processing  
operations, such as horizontal shifting,  
with ADSP.  
If the signal cable between the interface and the  
display device is shorter than approximately  
125 feet, and the gain/peak switch is set to a setting  
other than unity, the image may be overly bright  
(overcompensated).  
3 — SERR (serration pulse) — Many display  
devices, including LCD and DLP projectors and  
plasma displays, must have serration pulses  
removed from the sync signal in order to display

ON — When this switch is set to On, serration  
pulses will be output in the vertical sync  
interval.  
Setting Internal Jumpers  
OFF — When this switch is set to Off, serration

The jumpers inside the interface(s) are set at the factory to meet  
the requirements of most systems. However, you can change  
a jumper setting to meet the needs of a particular system.  
4 — 75 Ohm (video input termination) —  
RGB 138xi only — Video termination is  
accomplished in a number of ways when using a  
universal interface like the RGB 138xi:  
Changes to internal jumper settings must be  
performed by authorized service personnel only.  
The user-configurable, internal jumpers control the  
following functions:  
1. Setting the 75 ohm termination switch on the  
interface when using an MBC cable without a  
local monitor attached,  
• horizontal and vertical sync polarity, and  
• vertical sync pulse width.  
2. Using a laptop breakout cable (LBC)  
connected to a laptop or desktop computer  
with no local monitor,  
Follow these steps to change the jumper settings. The  
RGB 138xi is shown for illustration, but the steps apply to  
both models.  
3. Connecting a local monitor to the breakout  
from an MBC cable,  
1. Remove power from the interface (if it is connected) by  
disconnecting the AC power cord from the unit.  
4. Using a termination adapter with an MBC  
cable and no local monitor attached, or  
2. Open the cover of the interface (the top half of the  
enclosure), as shown below. Remove the screws  
from the enclosure, and lift the cover straight up.  
5. Using an MBC buffer cable.  
The input to the interface is high impedance, and  
for the video signal to be at a proper level (not  
blooming) 75 ohm termination is needed for the  
computer signal. The switch provides a method  
of termination to prevent blooming  
Do not touch any switches or electronic  
components inside the interface. Doing so  
could damage the interface.

Installing Adapter Plates  
The RGB 138xi and RGB 158xi offer the ability to incorporate  
a variety of optional architectural adapter plates for pass-  
through audio and/or video connections. Each interface  
can hold up to four (4) adapter plates.  
Blank plates (two single height and one double height  
plate) are included with the interface to cover unused  
spaces. Other adapter plates must be ordered separately.  
The plates attach to the front panel. Output cables attached  
to the rear of each plate pass through the interface  
enclosure and rear panel and are held in place by clamps.  
Some adapters require wires to be soldered to the rear  
connectors.

Troubleshooting  
RGB 138xi, RGB 158xi  
When the interface, computer and output devices have  
been properly installed, and the power is turned on, the  
image should appear on screen, and sound should be  
audible.  
If the image does not appear or there is no sound  
1. Ensure that all devices are plugged in.  
2. Make sure that each device is receiving power. The  
power indicator LED should light if the interface is  
powered on.  
3. Check the cabling and the audio connector wiring, and  
make adjustments as needed.  
4. Verify that the video input termination DIP switch on  
the RGB 138xi and the ID bit termination DIP  
switches on the RGB 158xi have been set correctly.  
5. For digital display devices, try switching between ADSP  
and DDSP using the rear panel DDSP DIP switch.  
Appendix A  
6. Call Extron’s customer support hotline if needed.  
If the image does not display correctly  
A
1. If the output image looks too green, make sure that the  
sync on green feature (SOG DIP switch) is turned  
off.  
2. If the picture bends or flags at the top of the screen, set  
the SERR (serration pulse) DIP switch to Off.  
Specifications  
3. For a display device that experiences intermittent  
glitches, try switching between ADSP and DDSP  
using the rear panel DDSP DIP switch.  
4. If the picture “hangs off” the edges of the screen, adjust  
the centering controls.  
5. If the edges of the image seem to exceed their  
boundaries or if thin lines and sharp edges look  
thick and fuzzy, try changing the GAIN/PEAK  
setting.  
6. If the image still does not display correctly, call Extron’s  
customer support hotline.
