LIGHTWARE HDMI-TPS-TX97 Twisted Pair Transmitter User Guide

Important Safety Instructions

Please read the supplied safety instruction document before using the product and keep it available for future reference.

Introduction

TPS-TX97 and RX97 twisted pair HD Base TTM 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, IR, and Ethernet 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. PoE 48V remote powering is available through the single CATx cable, but a local power supply can also be used.

Box Contents

Compatible Devices

TPS-97 extenders are compatible with all Light ware devices with TPS port except the TPS-90 series.

Power Supply Options

TPS-97 extenders are compatible with IEEE 802.3af standard – Power over Ethernet (PoE) and can receive power over the TPS line.

The extenders are not compatible with TPS-95 extenders from remote power point of view. TPS-95 extenders have different remote power feature which is not Poe compatible. Please check the devices always before connecting them to each other. If the remote power feature is disabled on the TPS-95 extender, it can be connected to a TPS-97 device.

The extenders can be powered:

Locally with the supplied 12V DC adaptor or Light ware’s rack mountable PSU,
Remotely by a PoE-compatible Power Sourcing Equipment (PSE) device, like Light ware’s power injector (TPS-PI-1P1) or a PoE-compatible matrix or matrix board.

If both supplying modes are available (local and remote) the remote power supply will be used.

Do not connect any device to the TPS connector unless you are sure they are compatible! Connecting incompatible devices with similar connectors may cause harm to the devices.

AWG 26 cables are not recommended with remote powering (reduce cable distances)

Connecting Steps

Below layout means the transmitter is powered locally by the power injector and they are placed close to each other. The receiver is powered remotely via the TPS cable (PoE)
Connecting Steps

CATx
DVI Connect the TPS output port of the TX to the TPS port of the power injector by a CATx cable.

CATx
DVI Connect the TPS input port of the RX to the TPS+ PoE port of the power injector by a CATx cable.

DC-DC

LAN
Optionally connect a laptop to the Ethernet port of the transmitter

HDMI
Connect a sink device to the HDMI (DVI-D) output port of the receiver.

RS-232
Connect a serial cable between the sink device and the RS-232 port of the receiver.

CATx
Connect the receiver to Ethernet by a CATx cable.

IR

Power
Firstly connect the power adaptor to the DC input of the power injector, then secondly to the AC power socket.

Infrared emitter and detector units are optionally available accessories.

Locking DC Plug

The device has a locking DC connector to establish robust and safe power connection when local PSU is used. Twist 90° clockwise to lock.

Mounting Options

Light ware offers three types of mounting accessory to fix the extenders:

Rack Shelf
1U high rack shelf provides mounting holes for fastening up to four extenders.

Mounting Steps:

Always use the fixing screws which 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).

Under Desk Mounting Kit (UD-kit)
The UD-kit makes easy to mount one extender under any flat surface (e.g. furniture).

UD Mounting Kit Double (UD-kit double)
The UD-kit double makes easy to mount two extenders under any flat surface (e.g. furniture).

Installation of the Extender With a Matrix

Power off all devices (installing with powered devices may harm them).
Check the RS-232 switch(es) on the extender(s); they must be in Normal position for RS-232 pass-through function.
The state of the TPS link mode switch makes no difference on the extender because the connected board forces the extender to use the settings of the matrix.
Check the PoE settings of the matrix or the matrix board (with the LDC software); each port can be set for remote powering separately.
Pair the extender(s) and the matrix board(s) with CATx cable(s). The transmitters’ TPS OUT with the input boards’ TPS IN and the receivers’ TPS IN with the output boards’ TPS OUT.
Connect the video source(s), sink(s) and the desired accessory device(s) to the matrix (MX-TPS boards don’t support the IR pass-through).
Connect the video source(s), sink(s) and the desired accessory device(s) to the extenders.
To supply the extender(s) with remote power supply connect the necessary power adaptor to the given matrix board.
To supply the extenders locally connect the supplied adaptor (12V 2A DC).
Connect the power cord of the matrix into the outlet and switch on the matrix.
Supply the other connected units.

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, IR, Ethernet source and sink devices can be connected either to the TX or to the RX and the signal is transmitted to the other extender.
Bi-directional Pass-through Data Lines

In fact IR transmission is uni-directional but the extender has two IR channels with different directions.

RS-232
Third party devices with standard RS-232 port are supported as the extenders work in „pass through” mode. TX and RX provide 3-pole Phoenix connector. The RS-232 options – the baud rate and the parity bits are set on the third party devices and it can be anything. The extenders support any kind of serial settings.

Please find the RS-232 device type in its user guide; the extenders work as DCE devices.

Ethernet
The Ethernet port on the RX or on TX can be connected to a LAN hub, switch or router with a LAN cable. The other side behaves as an Ethernet uplink port. The extenders support 10/100 Mbps data transfer rate. The Ethernet port has auto crossover function. It is able to recognize and handle both cable types: patch and cross TP cables.

Infrared (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 Output Mode Switch

The TPS working mode between the transmitter and the receiver parties is determined by the mode set in them. Both parties influence on the setting which 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.
HD Base TTM (HDBT): more bandwidth (higher resolutions), shorter CATx cable length. If no video present, the units change to LPPF mode automatically.
Low Power Partial Functionality (LPPF): Only Ethernet, RS-232 and IR are extended.

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 mode.

The negotiated TPS working mode	Selected mode (RX)
LR	Auto
Selected mode (TX)	LR
Auto	LR

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 extender to use the settings of the matrix. The extender’s TPS mode switch has no effect.

Always use the Auto mode with third-party devices!
