1. Introduction

Thank you for choosing Lightware’s TPS-PI-1P1 device. In the first chapter we would like to introduce the device by highlighting the most important features in the sections listed below:

1.1. Description

TPS-PI-1P1 is an IEEE 802.3at compatible high end remote Power Injector (PI) unit providing power to a remote Powered Device (PD) e.g. TPS transmitter or receiver. The TPS-PI-1P1 placed in the TPS transmission chain, anywhere between the transmitter and the receiver unit via the CATx* cable is able to power a TPS device. The incoming data stays untouched, but a 48V DC remote power is added to the signal by this PI.

* CAT7 AWG 23 SFTP cable is always recommended.

INFO:Comparing to the details of the powered device’s extension distance chart the usage of the TPS-PI-1P1 may cause approximately 20% distance decrease depending on the powering mode (local or remote) and cable quality.

About the Serial Number

Lightware devices contain a label indicating the unique serial number of the product. The structure is the following:

From 1st of October 2024, serial number format of Lightware devices is the following: the first two digits are of the year of manufacture, while the remaining digits make up the running sequence number.

Compatible Devices

The power injector can be used to supply power any PoE-compatible Lightware extenders which are based on TPS-technology, except the TPS-90- and TPS-95-series.

ATTENTION!The TPS-TX/RX90 and TPS-TX/RX95 extenders are not PoE-compatible thus not able to send/receive power to/from TPS-PI-1P1 power injector.

1.2. Box Contents

The assembling of certain accessories can be found in the Mounting Options - Compatibility Table section.

2. Product Overview

The following sections are about the physical structure of the device, input/ output ports and connectors; software and hardware capabilities:

2.1. Front and Rear View

	Status LEDs	The LEDs give immediate feedback about the current powering status of the device. See the details in the Status LEDs section (on the right).
	48V DC input	48V DC input for local power supply.
	TPS port	TPS (HDBaseTTM) port for local powered TPS extenders. The port is not PoE-compatible.
	TPS + PoE port	TPS (HDBaseTTM) port for remote powered TPS extenders. The port is PoE-compatible and fulfills the IEEE 802.3at remote powering standard.
	12V DC output	DC power outlet for local powered TPS extenders.

See the connecting steps of the power injector and the connected TPS extenders in the Connecting Steps section.

2.2. Status LEDs

REQUIRED POWER OVER 20W
	off	The delivered power of the wall adaptor is less than 75% of the maximum value.
	on (red)	The delivered power of the wall adaptor exceeds 75% of the maximum value.
12V DC OUT ACTIVE
	off	The 12V DC out is out of order.
	on (green)	Device is connected to the 12V DC output connector.
REMOTE POWER OUT ACTIVE
	off	There is no PoE compliant device at the remote side or the identification process was unsuccessful. The Power Injector does not send power over the CATx cable.
	on (green)	The remote unit is a valid PoE device and gets the power via the TPS line in this case.
48V DC IN PRESENT
	off	The 48V DC input is not connected. If it is connected, the voltage level is not enough for the proper operation (it is lower than 40V DC).
	on (green)	The 48V DC input is connected and the voltage level is proper (it is lower than 40V DC).

INFO:TPS-PI-1P1 does not apply current limitation but only indicates the overload.

INFO:The 12V DC out cannot be disabled in normal operation. If it is not working please contact support@lightware.com.

3. Installation

This chapter is about the installation of the device and connecting to other appliances, also presenting the mounting options and further assembly steps:

3.1. Mounting Options - Compatibility Table

The following table summarizes the compatibility of the HDMI-TPS-87 series devices with the mounting accessories offered by Lightware. The number in the brackets means how many same-size devices can be assembled to the mounting plate. The dimensions are in mm. The following accessories can be ordered separately, please contact sales@lightware.com for the details.

		100.4 W x 67.6 D x 26 H
		TPS-PI-1P1
	1U High Rack Shelf	(4x)
	UD Mounting Kit	(1x)
	UD Mounting Kit Double	(2x)
	UD Mounting Plate F110	(1x)

INFO:See the details about the assembly steps for each model in our Mounting Assembly Guide downloaded from the website.

3.2. Electrical Connections

3.2.1. Ethernet Connectors

TPS Connector

The power injector unit provides standard RJ45 connectors for TPS ports. Maximum CATx cable distances can be found in the Maximum Cable Extensions section.

Wiring of CATx Cables

Lightware recommends the termination of LAN cables on the basis of TIA/EIA T 568 A or TIA/EIA T 568 B standards.

3.2.2. 48V DC Input Connector

The power injector unit is built with a 2-pole Phoenix connector for 48V DC 1.25A power connection.

2-pole Phoenix connector and plug pin assignments

WARNING!Always use the supplied 48V power adaptor. Warranty void if damage occurs due to use of a different power source.

3.2.3. DC 12V Output Connector

Locking DC connector

Do not forget to turn the plug counterclockwise before disconnecting the power cable.

3.3. Powering Options

This unit provides a uni-directional remote power only, but thanks to the 12V DC local output option the other device (e.g. HDMI-TPS-RX95) can be powered with the TPS-PI-1P1 if they are placed close to each other while the injector itself is powered by the supplied adaptor.

The Power Scheme

WARNING!The sum of the power of the two outputs must be under 30W.

3.4. Ventillation

The enclosure of the TPS-PI-1P1 has vent holes on the left and the right side, as well. These holes provide the cooling by convection.

WARNING!Do not block the vent holes otherwise the unit can be overheated.

INFO:The appropriate operation of the unit is not guaranteed with 40V DC or lower input voltage. In this case if the identification and the classification were successful, the TPS-PI-1P1 switches the inadequate voltage to the TPS line, but the remote powering can be failed. Always use the supplied power adaptors of the devices.

3.5. Connecting Steps

Step 1.Switch off (disconnect) all units, even the video, audio or data devices. Make sure there are no powered units during the installation.

Step 2.Connect the TPS device to be remote powered (e.g. HDMI-TPS-RX97 receiver) to the TPS+PoE connector of the TPS-PI-1P1 Power Injector with a CATx cable.

Step 3.Connect the TPS device to be local powered (e.g. HDMI-TPS-TX97 transmitter) to the TPS connector of the TPS-PI-1P1 Power Injector with a CATx cable.

Step 4.Connect the desired video, audio and data devices (e.g. Blu-ray players, amplifiers, Ethernet switch, RS-232 controller, IR transmitter) to the TPS units. Please read the user manuals of all devices to get help during the installation process.

Step 5.Switch on the devices according to the following sequence:

▪The Power Injector with connecting firstly the 48V DC adaptor to the 48 DC IN connector secondly to the socket. The remote device gets power immediately.

▪The local powered device

=with connecting its adaptor or

=with connecting the supplied patch cable* to the 12V DC OUT 5 of the Power Injector.

▪Switch on the other devices.

* CAB-12V-U16U (Part No: 13730013)

ATTENTION!The maximum distance of the TPS units will not expand by using TPS-PI-1P1.

WARNING!Warning! Always use the supplied power adaptors. Warranty void if damage occurs due to use of a different power source.
