Thank you for purchasing the Luxi Electronics® SHD-310SM
switcher scaler. Please read through this manual before using
the product.
How the product functions: Please refer to the “Video signal
path” and “Audio signal path” sections in the right column of the
specs on page 4 for details.
Power options: This product draws power from an external 12 V power supply sold separately (Luxi P/N
69-002-01). Do NOT plug the power supply connector into any other connectors; this could cause
permanent damages to the product and void the warranty.
Captive screw plug termination: The captive
screw plugs for power, audio, RS-232 and
contact controls are supplied with the unit.
Separate the wires about 1” (2.5 cm) long;
strip off the wire insulation precisely 3/16” (5
mm) from the end. Identify the positive and
negative leads for power; Luxi power supply
has a white stripe on the positive wire. If not
sure, use a multi meter to verify.
Mounting options: Luxi has the under desk mount sold separately (Luxi P/N 78-002-01); the product
also fits many other mounting hardware from Extron, Middle Atlantic, etc. Only use the type 4-40, 3/16”
(5 mm) long screws supplied with the mounting hardware to screw onto the product. Wrong type of
screw could strip the threads; too long screw could touch and short the internal circuit, cause
permanent damages to the product and void the warranty.
Control options: Pressing the “Input Sel.” button on the front panel
will toggle thru the 3 video inputs. 3 sets of external contact closure
push buttons and LEDs can select inputs discretely with the LED
indication, see wiring diagram on the right side; when a button is
pressed, the associated LED would blink once, then stay on. A RS-
232 host connected to the rear panel can control all functions, see
page 3 for the RS-232 commands and responses.
Auto input switching: when activated by a RS-232 command, the
switcher will select the last connected input with active signal as the

current input. Auto switching is turned off after any front panel, external button push, or a RS-232 input
command. Default is auto switching off. Note: due to the nature of the wide varieties of the DP product
designs, some DP source devices may not trigger the auto switch. Use manual switch when this
happens.
Audio output connector wiring: refer to the diagrams on the right for
the wiring to the 5-pin captive screw connector. Do NOT connect the
sleeve (audio cable shield) to the “-” pin of the audio output; this could
cause permanent damages to the product and void the warranty.
RS-232 controls: Only the input selections can be controlled by front
panel or external buttons; all other functions can only by controlled by
RS-232. See the RS-232 Setup Guide on Luxi website for more
information: http://luxielectronics.com/attachments/File/Luxi_RS-
232_setup_guide.pdf. Refer to page 3 for RS-232 commands and
responses.
Input select commands: Command “s” is to check the current selected input; “0s” is to enable auto
switching; “1s” is to select VGA input, “2s” HDMI input; “3s” DP input. There will be a blank screen for a
brief period of time during input switching. The length of the duration depends on the handshake time
of the display and the source device, and the input and output resolutions, generally around 2 seconds
or less. Note: the DP input only works with the source devices compatible with DP++ (dual mode).
Front panel and contact closure lockup: Command “A” is to check the current front panel switch status;
“0A” is to defeat front panel and contact closure controls; “1A” (default) is to allow front panel and
contact closure controls.
Auto image settings: Command “a” is to initiate auto image settings.
Scaler output video format settings: Command “o” is to check the current output video format; “1o” is
to set the output to 720p; “2o” (default) is to set the output to 1080p; “3o” is to set the output to “Pixel to
pixel” (source device to match display’s native resolution).
Image size (zoom) adjustments: Many displays made by consumer electronics manufacturers tend to
set the image on the screen in overscan even fed by computer signals, making the menu icons on the
sides cut off or disappear. Use the “z” commands to set (shrink) the proper picture size on screen.
Command “z” is to check the current zoom level; “1z” is to set the zoom level to 1 (default, same size as
the original in a non-overscan display), “2z”, “3z”, … “6z” are to set the zoom levels to 2, 3, … 6,
respectively.
Audio mode commands: Command “M” is to check the current audio status; “0M” is to mute the audio
from the HDMI outputs (note the audio from the 5-pin connector is not affected); “1M” is to send digital
audio from the HDMI or DP inputs directly to the HDMI outputs in their original format (default, use this
option to retain the surround sound modes); “2M” is to mix the front panel analog audio input with the
de-embedded audio from HDMI or DP inputs, and embed and send to the HDMI outputs. The 5-pin
audio outputs always send the mixed audio between the front panel analog audio input and the de-
embedded audio from HDMI or DP inputs regardless the audio mode settings.
Resetting the product to factory defaults: Use the RS-232 command “r” to reset the product to factory
defaults. See page 3 for the default values.
Support: Please contact your reseller directly for local support; or Luxi using the contact info in the
header. See Luxi website for additional and more updated documents.
