LIGHTWARE TX86 HDBaseT HDMI IR RS-232 over Twisted Pair Transmitter
Important Safety Instructions
Please read the supplied safety instruction document before using the product
and keep it available for future reference.
Introduction
HDMI-TPS-TX86 and -RX86 twisted pair HDBaseTTM extenders provide extension of uncompressed 4K/UHD video with embedded audio for long distances over a single CATx cable. The extender offers uni-directional RS-232 and IR pass-through on the same CATx cable that carries the video signal. The TPS extenders support full HDCP and EDID compliance and work on all standard AV resolutions and also 120 Hz 3D signals. 12V remote powering is available through the single CATx cable, but a local power supply can also be used.

Compatible Devices
It is not recommended to be used with third-party HDBaseTTM devices due to the
special remote powering feature of the device.

- RS-232 port Local RS-232 port for bi-directional serial data connection and performing firmware update (programming).
- RS-232 switch Normal : serial data is passed through the device. Prog: RS-232 pass-through function is disabled, the device is ready for the firmware update.
- Status LEDs: See the next section.
- TPS mode switch
- LR : Long reach TPS mode; lower resolution (max 1080p), longer distances; Auto: TPS mode is determined automatically.
- IR mode switch: IR output signal modulation switch; the 38 kHz modulation can be switched On (Emitter position) or Off (Wired position).
- IR input: IR signal input connector (for 3.5 mm Jack, 3-pole, TRS plug).

Connecting Steps
Mounting the Device (with optionally available accessories)
- Under Desk Mounting Kit (UD-kit) : to mount one extender under any flat surface (e.g. furniture)
- UD Mounting Kit Double (UD-kit double) : to mount two extenders under any flat surface (e.g. furniture).
- Rack Shelf : 1U high rack shelf provides mounting holes for the fastening of up to four extenders
Always use the fixing screws that are supplied with the mounting accessory. If you insert screws longer than 6 mm, the device can be damaged.
- Unplug all the cables connected to the device(s).
- Turn the device(s) upside down.
- Put the shelf upside down on the device(s). Position it to get the mounting holes aligned.
- Fasten the device on the shelf with the provided screws.
- Fix the shelf to the desired place (screws are not supplied).
Locking DC Plug
Power Supply Options
The extenders can be powered by any of the following ways:
- Local adaptor: 12V DC input for local power supply.
- Remote power: The extender pair can power each other when one of them is locally supplied with 12V DC adaptor. The extender sends remote power via the TPS IN (on the receiver) or the TPS OUT (on the transmitter) RJ45 connector to other device
Carefully read all the detailed instructions about remote powering devices! Never use remote powering with third-party units!
Maximum Extension Distances
The values below are valid when the transmitter is powered by a local adaptor;
distances may decrease depending on the powering mode (local or remote) and
cable quality.

Long reach TPS mode supports pixel clock frequencies up to 148.5 MHz. CAT7 SFTP AWG23 cable is always recommended.
TPS Link Modes
The TPS working mode between the transmitter and the receiver parties is
determined by the mode set in them. Both parties influence the setting that
determines the final TPS transmission mode. The following TPS modes are
defined:
- Long reach (LR): Longer CATx cable length, less bandwidth (limited resolution). The LPPF mode is not available in LR TPS link mode.
- HDBaseTTM (HDBT): more bandwidth (higher resolutions), shorter CATx cable length. If no video is present, the units change to LPPF mode automatically.
- Low Power Partial Functionality (LPPF): Only RS-232 and IR are extended (@9600 baud).
Toggling Between TPS Link Modes
The toggle switch on the extenders can be used to toggle between the LR and
Auto TPS modes. If both units have Auto state and there is valid video signal
on the transmitter, the common mode will be HDBT. If the video signal
disappears, devices go into LPPF mod
TPS mode between an extender and a port of a matrix board
If an extender and a TPS matrix board are paired, the board forces the
extenderto use the settings of the matrix. The extender’s TPS mode switch has
no effect.
- Always use the Auto mode with third-party devices!
Application diagram
Bi-directional Pass-through Data Lines
The direction of the video extension is fixed from TX towards RX, but the
pass-through data lines are bi-directional. It means the RS-232 and IR source
and sink devices can be connected either to the TX or the RX.
Infra-Red (IR)
One emitter and one detector is enough for remote controlling one IR sink
device. If there is an IR sink device to be controlled next to the TX and the
other one is next to the RX, two emitter- detector pairs are needed. The IR
emitter and the detector have standard 3.5 mm TRS (jack) connectors. The
emitter’s plug has two poles (mono) and the detector’s plug has three poles
(stereo).
IR extension is available only with point-to-point connection of the extenders.
Mechanical Drawings (HDMI-TPS-RX86)
Dimensions are in mm. Both the transmitter and the receiver have the same
sized enclosure.
RS-232
Third-party devices with standard RS-232 port are supported, as the extenders
work in passthrough mode. TX and RX provide a 3-pole Phoenix connector. Use
straight-serial cable to connect a DTE device to an extender and use a cross
serial cable in case of pairing a DCE device to the other TPS extender. The
RS-232 options – the baud rate and the parity bits – are set on the third
party devices and they can be anything. The extenders support any kind of
serial settings.
The signal levels are the following:
| Output voltage (V)
---|---
Logic low level| 3 – 15
Logic high level| -15 – 3
RS-232 connector and plug pin assignment
| Pin nr. | Signal |
|---|---|
| 1 | Ground |
| 2 | TX data |
| 3 | RX data |
Please read the user’s manual of the RS-232 device to get its type. The extenders operate as a DCE unit according to its pin-out.
Wiring Guide for RS-232 Data Transmission
HDMI-TPS-86 series are built with a 3-pole Phoenix connector. See the
examples below of connecting to a DCE (Data Circuit-terminating Equipment) or
a DTE (Data Terminal Equipment) type device:
