1 Introducing the Leaf True Video Matrix system
1.1 Overview
The Leaf True HDMI Matrix System comprises a Leaf LT88 or LT88E interface unit and
Leaf LTB1 or LTB1E breakouts. The Leaf True Video Matrix system is designed to
accept HDMI A/V sources at its inputs and route them to remotely located breakouts. In
this document, each input signal source is termed a
source and each output and
breakout is called a zone.
Additional features include infrared (IR) control through feed and RS232 through feed
capability between the interface and breakouts. Note that these are through feeds only
and have no direct control function of the Leaf True system.
There are 2 model variants:
LT88 interface with LTB1 breakouts and
LT88E interface with LTB1E breakouts.
Whilst both model variants provide the routing and control features, the LT88E extends
this by providing Ethernet through feed capability. The LT88E has additional circuitry
and dedicated RJ45 type ports on its front panel that connect to matching Ethernet
ports at LTB1E breakouts.
Interconnection between a Leaf True interface and associated Leaf True breakouts is
via one single cat5e/6 cable for each breakout. Single cat5e /6 cable interconnect
between these components is made possible through the use of HDBaseT technology.
This technology enables Video and Audio, as well as Ethernet, IR, and RS232 through
feed to be all sent by a single cable per zone over large distances.
Cabling specifications and information can be found in supplementary documentation.
The Leaf True system is designed to be controlled via RS232 commands from 3
rd
party
control systems. Control of basic switching functions can be (also or instead) achieved
via a proprietary Leaf controller such as the Leaf TC3 connected by 6 wire Telco cable
and RJ12 (6P6C) modular connectors.
