Thank you for purchasing the Luxi Electronics® THB-350 scaler
transmitter. Please read through this manual before using the
product.
How the product functions: To use the 2nd video output for
remote locations, this product needs to be connected to a Luxi
RHB-350 or a compatible HDBT receiver with POC or POE
turned off; failure to turn it off may cause damages and void warranty. Please refer to the “Video signal
path” and “Audio signal path” sections in the right column of the specs on page 5 for details.
Power options: This product draws power from an external 24 V power supply sold separately (Luxi P/N
69-008-01).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 (Luxi P/N 78-002-01) or the MediaHub table tanks
sold separately; 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: When auto switching off, 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
this or RHB-350 can control all functions, see page 3 for the RS-232
commands.

Auto input switching: The default is auto switching on, front panel button defeated. When the button
pressed, the 3 LEDs next to it will blink 3 times. To turn off auto switching, press and hold the button
for about 7 seconds until the LEDs blink twice, or use RS-232 command. When auto switching off, use
the button or contact closure buttons or RS-232 to select input. To engage auto switching again, press
and hold the button for more about 7 seconds until the LEDs blink 3 times, or use RS-232 command.
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.
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 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.
Front panel and contact closure lockup: Command “A” is to check the current front panel switch status;
“0A” is to turn off auto switching and defeat front panel and contact closure controls; “1A” is to turn off
auto switching and allow front panel and contact closure controls; “2A” (default) is to turn on auto
switching and defeat front panel/contact closure controls.
Auto image settings: Command “a” is to initiate auto image settings.
Scaler output video format settings: Refer to RS-232 “o” series commands on page 3 for more details.
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.
Video output commands: Refer to RS-232 “m” series commands on page 3 for more details. If the
monitors can go to sleep without input signal and can wake up with input signal, use RS-232 command
“1m” to enable this feature. If your projector needs screen saver to prevent burn in, use command “2m”
to turn on OSD (On Screen Display) when no input signal.
Audio commands: Refer to RS-232 “M” series commands on page 3 for more details. Use RS-232
command “0M” to mute all audio outputs; “1M” to set digital audio pass thru for preserving the movie
surround sound; “2M” to mix the 3.5 mm audio to input digital audio; “3M” to pair the 3.5 mm audio with
VGA input only; “4M” to use the 3.5 mm audio all the time (for wireless microphone).
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.
Display power controls: THB-350 has the configurable display power control feature to enable fully
automated system operations without any operator or 3rd party control devices. THB will send a display

power off command via RS-232 ports of both THB-350 and RHB-350 with a set delay time (1 to 60
minutes) after the last input signal disappears; and will send a display power on command as soon as
the first input signal detected, and will automatically select that input. The switcher uses one RS-232
port to connect both external host (optional; only required for setup) and display in parallel with the
display in “listening” mode only (only display’s Rx pin connected). Here’s the wiring diagram:
Ext host THB-350 RHB-350 Display
Rx -------------- Tx Tx -------------- Rx
Tx -------------- Rx Via Cat6 Rx NC NC
Ground -------------- Ground Ground -------------- Ground
NC = Not Connected
Use the “2{xxx}R” and “1{yyy}R” commands listed in next page to setup the display power on and off
commands respectively, then use the “1*zR” command to enable the display power control feature
while setting the power off delay time at “z” minutes. Use “0R” command to disable the display power
control feature. Once setup finished, the external host is not needed for daily operations. The system
reset command “r” will not erase the stored display power on and off commands, but will disable the
display power control feature (factory default).
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.
