Overview And Uses
DA4X-R
SPDIF 4x1
Digital Audio Switcher
Toslink and Coax Inputs
With IR Remote Control
& RS-232 Serial Option
(Compatible with the RGB4X-R)
The DA4X-R is a 4x1 SPDIF Digital Audio
Switcher. It can take up to 8 inputs ( 4-Toslink
and 4-Coax) and send one of those inputs to
both outputs simultaneously.
The inputs can be any standard Consumer
digital Audio type such as:
- SPDIF( IEC 958) format Audio.
- Toslink/Coax
- DTS/Dolby Digital/AC3/PCM
Please note that If you connect both Toslink
and Coax to a single input, it will default to the
Coax input, if a signal is present.
The DA4X-R does not “process” the audio in
any way. So if the source is DTS encoded on
the input, it will be DTS encoded on the output.
The only conversion that takes place is be-
tween the Optical and Coax.
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.

Questions
Specifications
The DA4X-R comes with a 10
button IR Remote that is ar-
ranged in 2 groups of 5 but-
tons.
The DA4X-R can be pro-
grammed to respond to either
one of these groups.
The DA4X-R is initially pro-
grammed to use the right side
group of buttons. You may
want to re-program the unit to
use the left side buttons in the
following situations:
1. You have two DA4X-R
and want to operate them
separately.
2. You have an RGB4X-R
Component Video
Switcher and you want
them to switch in sync
with one button push
3. You like the left side bet-
ter!
Perform the following steps to
Re-program the DA4X-R
1-Remove power from the
unit by unplugging the 12VDC
Connector
2-Press and hold the front
panel button
3-Apply power to the unit.
4-Release the front panel but-
ton after the display stops
blinking.
Each time you perform this
operation you are alternating
the button group used on the
IR remote.

Q: Can I use both Toslink and Coax inputs?
A: Yes! The output will default to the coax input
if there is a signal present. If you turn off the
source feeding the Coax input, it will switch to the
Toslink input. Please note that some equipment
will send a signal even in the stop mode.
Q: I have a RGB4X-R Component Video
Switcher. How can I operate the DA4X-R so the
remote does not switch the RGB4X-R
A: See the “Remote Control” section on pro-
gramming the remote to use an alternate set of
remote buttons.
RS-232 Control Option
RS-232 serial control is provided through a
3.5mm stereo jack on the rear panel. A 3.5mm
to DB9 crossover cable is provided. Any Termi-
nal 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 DA4X-R to respond with its help mes-
sage:
“DA4X-R Online! Type "S" for Status,
Numbers 1-4 for control.”
For current status, type the character “S” fol-
lowed 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 DA4X-R is in a powered-off mode via the IR
remote control, any Serial port activity will restore
power.
