1  Introducing the Leaf True Matrix system 

1.1  Overview 

The  Leaf  True  HDMI  Matrix  System  comprises  a  Leaf 

LTHDMI88

  or 

LTHDMI88E

 

interface unit and Leaf 

LTB1

 or 

LTB1E

 breakouts. The Leaf True HDMI 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 and RS232 feed capability between the 
interface and breakouts. 

There are 2 model variants: 

LTHDMI88 interface with LTB1 breakouts  and 

LTHDMI88E interface with LTB1E breakouts. 

Whilst  both  model  variants  provide  the  routing  and  control  features,  the  LTHDMI88E 
extends this by providing Ethernet capability.  The LTHDMI88E 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  Ethernet,  IR,  RS232,  Video  and  Audio  to  be  all  sent  by  a 
single cable per zone over large distances.  

Cabling  specifications  and  information  can  be  found  in  supplementary  documentation  
available on request from Leaf. 

Control  of the  basic  switching functions  of  the  LTHDMI88  and  LTHDMI88E  interfaces 
can  be  achieved  by  the  use  of  front  panel  mounted  buttons.  A  corresponding  set  of  
display  LEDs  provide  user  feedback  of  the  signal  routing.  Wired  control  of  basic 
functions is available  via a proprietary Leaf controller  such as the Leaf TC3 whilst full 
feature control capability is available via RS232 from 3

rd

 party control systems. 

Both  the  LTHDMI88  and  the  LTHDMI88E  are  built  into  2RU  rack-mountable  metal 
housings  and  are  provided  with  rubber  feet  should  table  /  desktop  mounting  be 
preferred.
