Thank you for purchasing the Luxi Electronics® TPR-150CR
Presenter® transmitter. Please read through this guide before
using the product.
How the product functions:The TPR-150CR has 2 PCBs. The
front PCB has the switcher and scaler; please refer to the “Video
signal path” and “Audio signal path” sections in the right column of
the specs on page 4 for details. The rear PCB has the daisy chain circuits. Think of the daisy chain as
the flow of a river; each transmitter (Tx) connects to a source device and loads the signal to the river
flow; each receiver (Rx) unloads the signal from the river flow and sends it to the display it is connected
to. The front panel and the RS-232 controls determine which source signal goes to which display.
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, 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 “Show Me” button on the front panel will
select the current box, or 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. Both front panel and external LEDs work like this: only one LED
associated with the active input is lit at any given time. When the
current box not selected in the daisy chain, the LED blinks slowly.
When the current box selected, LED is solid on. A RS-232 host
connected to the rear panel can control all functions.
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.
RS-232 controls: Only the Show Me/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.If RS-232
port does not seem to work, please double check the two bank DIP switches in a recessed window on
the bottom of the enclosure, and make sure they are in “00” (low) positions.
System query command: Command “q” is to check the daisy chain system size, and the current box ID.
Signal routing commands: Command “m*ns” is to send signal from box Txmto box Rxn. Command
“m*s” is to send signal from box Txmto all Rx. Command “n1,n2,n3,n4S” is to send audio to the 4
designated Rx boxes.
Pass thru commands: There are two types of them: Command “x*y{xxxx}Q” is to send RS-232
command from ext. host connected to box xto ext. slave connected to box y. Command “x*y(xxxx)Q”
is to send from ext. host connected to box xto box y. The responses will be routed back to ext. host.
Product information commands: Command “p” and “P” are used to get the box part number and
firmware version, respectively.
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 (default); “2o” 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.
Audio mode commands: Command “M” is to check the current audio status; “0M” is to mute the audio;
“1M” is to send digital audio from the HDMI or DP inputs directly to the output 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, then embed to output.
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.

Helpful tips:
1) Damages by plugging into the wrong port: The 110 Tx has a Show Me port which happens to
be the same 2-pin captive screw connector as the 12 V power connector. Be very careful not to
plug in the 12 V power into the Show Me port by accident. Although there are protection circuits
inside, the prolonged error can still burn the protection circuit and the main daisy chain IC.
2) Needs for the initial press: When a system powered up, the user need to press a Show Me
button or to send a routing command to a unit in the system to create a signal link. This applies
to even the system with only one Tx unit.
3) May need to press again: When a new link is created after the Show Me button press, the
source device and display will handshake and HDCP check again, and the time for completing
this depends on the source device and display involved. In the rare case when the handshake
and HDCP check time exceeds the Presenter time out period, the picture may not show. User
just needs to press the Show Me button again to see the image.
4) Initialization practice for a large system: When there are more than one Rx (displays) in a
system, at the initial power up, every source device needs to handshake and HDCP check with
every display through the Presenter daisy chain, this could take some time depending on the
number of devices and the communication speed of the devices involved. During this brief initial
handshake and HDCP check period, the signal link may not happen. The installer should
connector all Tx (source devices) and the first Rx (display) in a system during setup, wait for the
image shown after any Show Me button press, then link the 2nd Rx box to the 1st with a Cat6
cable, press any Show Me button until the image shown. Then add the 3rd, 4th etc Rx boxes one
by one when the system power is live. This procedure breaks down the many handshake and
HDCP checks into several groups, and each group is fast. Once finished, no need to do this
initialization sequence again unless the daisy chain system is power off again. It’s a good
practice to keep the daisy chain powered all the time. The communication is maintained between
the Presenter boxes and the displays even when the displays are powered off. The system with
only one Rx (display) does not need this initialization procedure.
5) System status for security and troubleshooting: One of the most useful command is the “q”
command. Send a “q” command to a RS232 port of any Presenter in a daisy chain, the port will
report back “Max Tx=M, Max Rx=N, Me=Txm or Rxn”. For example, if there are 8 Tx unit, 4 Rx
unit, the current box is the 3rd Rx box, the response would be “Max Tx=8, Max Rx=4, Me=Rx3.
The system will also send a “reset” message from all units’ RS232 ports when the system just
powered up or any system changes (like adding or removing a Presenter box or cable) occurs. If
the Presenter is used in a high security facility, the system monitoring engineer can program the
control system to send a “q” command to record how many Tx and Rx in a system every morning,
then send “q” again right after receiving a “reset” message, and compare the number of Tx and
Rx in a system. If any number changed, then there could be a security breach or component
failure at a specific location. For example, if the known systems size is 8 Tx and 4 Rx, and at any
moment the system size changed to 5 Tx and 4 Rx, then the breach or failure must be between
the Tx5 and Tx6. The engineer can program the control system to send a text message or phone
call to the security personnel to check anything wrong between Tx5 and Tx6. This also helps to
troubleshoot the system to pinpoint the poor cable or connection.
6) Link cable selections: Please use the unshielded Cat6 550 MHz rated 23 AWG solid conductor
cables to link the Presenter boxes whenever possible. The Cat5 cable does not have enough
bandwidth for long run. Shielded Cat6 or Cat7 cables have higher capacitance which reduces the
drivability of the Presenter boxes.
7) Max. and min. cable lengths: The max cable length between Presenter units varies depending
on the cable performance, source device drivability, display’s sensitivity and error correction, and
the signal data rate (resolution). It’s a good practice to first to use 720p (or the popular 1280x800
computer and projector resolution) in system setup, once working, and then change to higher
resolution if needed. Please use a min. 2 m long cable between Presenter boxes even for short
distance to prevent the accumulated signal over boost over the daisy chain.
