Setup
Connect your sources, such as HDTV Receivers and
DVD Players to the Inputs of the RGB4X.
Connect the Output of the RGB4X to the input of the
Display or other destination.
Note :
Most newer HDTV monitors are capable of sensing
what scan rate is being sent to it and will switch cor-
rectly. I most cases it’s either 480-progressive scan
(480P) or 1080-Interlaced (1080I). If your mixing
scan rates, you should verify that the monitor will
synchronize correctly to these inputs without having
reconfigure the Monitor setup. Please do this before
you connect the RGB4X
The RGB4X-R is a 4-Input to 1-Output wide-
band, three channel component video
switcher. Designed to enable switching of
HDTV or DVD progressive scan component
video to ONE destination. All Scan formats
are supported, including 480i, 480P, 720P,
1080i and 1080P.
With the large amount of money invested in
your Home Theater system these days, you
want to be sure that anything you install will
not degrade the final picture. This device will
not compromise your system. The RGB4X is
designed with only the best Switching IC’s and
High Current Video drivers available. We
don’t use mechanical relays or switches which
can eventually wear out. The RGB4X-R out-
put is capable of driving very long cable
lengths ( up to 100 meters) without degrada-
tion.
There are 3 ways to control the RGB4X-R.
1– Front Panel Switch for cycling through the
inputs. Each press advances the input.
2– IR Remote Control for direct selection of
desired input. Visit www.inday.com to
download “Universal” remote configuration
files, such as the Philips Pronto ™.
3- RS-232 Serial Port (optional) for direct com-
puter control and status. Useful for integrating
into advanced automated systems. See “RS-
232 Control” section for further information.
Although primarily used for expanding the in-
put selection of HDTV Monitors, this switcher
can also be used to switch any type of Analog
video including.
- HDTV Analog RGB/YPbPr signals.
- Standard Def. Analog RGB/YPbPr/Betacam
- Component DVD, Progressive or Interlaced.
- Composite Video (NTSC)
- SPDIF Digital Audio (PCM/AC3/DTS)

Questions
Q: Why No Looping Inputs.
A: Looping inputs are ones that bridge off an
unterminated input and send it to another input.
This lets you daisy chain the inputs and terminate
only at the last input. This works fine for Low Fre-
quency video like NTSC (composite) at 5MHz, but
not for High Frequency HDTV where frequencies
can reach over 100 MHz. The input must be termi-
nated to prevent reflections on the cable and main-
tain bandwidth.
Q: Can I switch Digital Audio (SPDIF).
A: Yes. SPDIF is just AES/EBU digital audio that
is designed to run over Coax cable just like
video and therefore can be switched the same
way

Troubleshooting
Problem: I now have noise or interference in the pic-
ture that was not there before.
Fix#1: The problem may be “cheap” cables. The
RGB4X is extremely wideband. The switching IC’s are
rated at 700MHz. That’s 166 times the normal band-
width of composite video (NTSC). If you use marginal
cables with poor shielding, external RF interference
will penetrate the cables and may cause this interfer-
ence. Consider your cables to be like your water
plumbing. If they leak, you have a problem! You can
fix this problem by using a quality coax cable, such as
type RG59.
Fix#2: Ground Loops can also cause noise and hum
bars. Try lifting the ground leads of your equipment by
using a “cheater plug”. This is a 2 prong AC adapter
without the ground prong, available at most hardware
stores.
The Remote Control has 10 but-
tons. Only 5 of which are active
at one time. The unit comes
programmed to respond to the
left side column of buttons. You
can program the unit to switch
using the right side buttons, if
desired. This facilitates using
two RGB4X-R’s in a system and
having independent control over
both.
Perform the following to repro-
gram the RGB4X-R:
1-Remove power from the unit by
unplugging the 12VDC Connec-
tor
2-Press and hold the front panel
button
3-Apply power to the unit.
4-Release the front panel button
after the display stops blinking.
Each time you perform this op-
eration you are alternating the
button group used on the IR re-
mote.
RS-232 Control Option
Inday www.inday.com
503-255-1451 Fax [phone]
1818 NE 140th Portland, OR 97230
RS-232 serial control is provided through a 3.5mm
stereo jack on the rear panel. A 3.5mm to DB9 cross-
over cable is provided. Any Terminal communications
program such as Windows “HyperTerminal” will work
for control.
Communications parameters are: 9600,N,8,1. See
specifications for wiring information.
Once connected, pressing the Enter key will cause the
RGB4X-R to respond with its help message:
“RGB4X-R Online! Type "S" for Status,
Numbers 1-4 for control.”
For current status, type the character “S” followed by
the “Enter” key. The current input is returned.
To switch inputs, type numbers 1, 2, 3 or 4 then
“Enter” . The unit will switch inputs and return a status
message.
All other characters will return the help message.
If the RGB4X-R is in a powered-off mode via the IR
remote control, any Serial port activity will restore
power.
