Attention:
During initial set up and during any changes to the
installation, please switch off and unplug mains power
(from this system and any equipment that is to be
connected to it) prior to connecting any leads / cables.
Plug in and switch power back on again after all
interconnection leads are in place.
Do not run HDBaseT / Zone Cat5e/6 cabling with or in
close parallel proximity to mains power cables.
Do not connect any part of this equipment to Power
Over Ethernet devices. Damage may result.
During operation the Leaf LHDMI66 and associated
LB1 breakouts may feel warm to the touch. This is
quite normal. Please ensure that these items have
sufficient cool air flow around them.

1 Introducing the Leaf True LHDMI66P
1.1 Overview
The Leaf True HDMI Matrix LHDMI66P package comprises a Leaf LHDMI66 interface
unit and six Leaf LB1 breakouts. It is designed to accept HDMI A/V sources at its
inputs on the LHDMI66 and route them to remotely located LB1 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 single direction
RS232 data transmission from the connected control system to any of the LB1
breakouts.
Interconnection between a Leaf True LHDMI66 and associated LB1 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, IR and RS232 data to be all sent by a
single cable per zone over distances of up to 60 –70 metres cable length.
Cabling specifications and information can be found in supplementary documentation.
The Leaf True system is designed to be controlled via RS232 commands from 3rd 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.
Manual control of the basic switching functions can be also be achieved by the use of
front panel mounted buttons on the LHDMI66. See 5.3 - 5.4 for details. A
corresponding set of display LEDs provide user feedback of the signal routing.
The LHDMI66 is built into a rack-mountable metal housing and is supplied with rack
mounting ears. It is also fitted with feet should table / desktop mounting be preferred.

2.1 RJ12 control port
The 6 wire RJ12 port enables the LHDMI66 to be controlled by a proprietary LEAF
controller such as the TC3.
2.2 4 way DIP switch module
The rear panel accessible 4 position DIP switch controls functionality of the LHDMI66.
The table below summarizes the settings:
NOTE: The interface will only read the DIP switch settings on power-up. The unit must
be powered off and then back on again for it to respond to any change of the DIP
switch settings.

2.3 3.5mm IR ports
The 3.5mm Remote IR connectors are used for routing external IR control signals in
one direction between the LHDMI66 and the connected LB1 breakouts. These
connections are treated as through connections. That is, IR port 1 connects to the
breakout connected to Zone 1, through to port 4 being connected to the breakout at
Zone 4.
The IR ports support direct connection and drive of Leaf “hammerhead” and other
compatible 5 volt, 3 wire (Tip Ring Sleeve / stereo plug) IR detectors to Leaf LB41 and
other compatible 2 wire (mono plug) IR blasters.
The system wide operating direction of the IR detectors and blasters (either Hub to
Zones or Zones to Hub) is configurable by DIP Switch 1.
If the IR Direction is set to “Hub to Zones” by DIP switch 1, the IR ports on the
LHDMI66 can be further configured by DIP Switch 2 to accept direct IR drive from an
external control system or similar instead of stand-alone IR detectors.
For this configuration, Stereo (Tip Ring Sleeve) 3.5mm leads must be used instead of
Mono leads for the IR interconnections from the control system to the Leaf LHDMI66.

Leaf LHDMI66 manual

The “Ring” connection of these leads at the LHDMI66 end (or both ends) must be left
“floating” / not connected.
(See table 1 for DIP switch configuration details.)
If the IR input type is set to IR RX detector (DIP Switch 2 OFF/down):
then the IR output will be automatically modulated at 38Khz.
If the IR input type is set to IR direct drive (DIP switch 1:ON/up & DIP switch 2 ON/up):
then the received IR input will be directly passed through to the IR output.
Any external IR drive voltage should not exceed 5V.
2.4 RS232 from control system to LB1 Breakouts
The LEAF True LHDMI66 system allows RS232 commands to be sent from a
connected control system directly to the RS232 (RJ45) ports on the LB1 breakouts.
This is achieved through specific commands in the Leaf Driver software. Refer to
specific Leaf Serial Command documentation for further information.
Connection from these ports to RS232 equipment would typically be achieved through
the use of RJ45 to DB9 RS232 adaptor leads. Leaf Audio has suitable RJ45 to RS232
(DB9) Female adaptor leads (LT45DB9Female) available for sale. Male DB9 RS232
connection may require the additional of M-M gender bender(s).
For convenience the pinouts of the RJ45 type RS232 port is shown below.
2.5 4 pin DIN power connector
The LHDMI66 requires 4 Pin 12V power.
WARNING. Failure to use the correct power supply as provided by Leaf Audio
may result in incorrect operation and / or damage to the Leaf True Matrix system.
The power supply is fitted with a locking connector. Be sure to slide back the
locking sleeve on the plug before attempting to connect or disconnect it at the
LHDMI66. Flat Side down is the correct orientation.

2.6 RS232 Serial Control connectors
The unit can be controlled by serial commands through the RS232 input port. Typically
this would be connected to a control system with a straight through DB9 Male to
Female RS232 lead. Some control systems may require only the TxD, RxD and Gnd
wires of an RS232 lead to be connected. The pin configurations of these 3 connections
on the DB9 plug is: TxD = Pin 2, RxD = Pin3, Gnd = Pin5.
2.6.1 Single LHDMI66 use
The RS232 Input port is used for controlling the unit.
The TERM (Termination) switch (ref: para 2.8) must be set to ON (Up).
2.6.2 Multiple LHDMI66 use
Multiple units can be chained together and addressed on the same RS232 link
by connecting the RS232 thru (out) port on one unit to the RS232 input port of
the next unit.
The last unit in the chain must have the TERM (Termination) switch (ref:para 2.8)
set to ON (Up), while all other units in the chain must have this switch set to OFF
(Down). The RS232 Input port is used for controlling the units.
2.7 Bank Select Switch
The 16 position rotary BANK switch selects the RS232 bank address for the unit
as per the following Bank Select Table.

2.8 RS232 Termination (TERM) Switch
The RS232 termination switch must be used to correctly terminate any RS232 control
connection as described in paragraphs 2.6.1 and 2.6.2.
2.9 HDMI Input ports
Standard HDMI input ports are provided for the purpose of connecting HDMI sources.
They are labelled 1 to 6.
All Leaf True systems accord with the HDMI 1.4 specification and includes support of
3D formats.
3 BREAKOUTS
A Breakout is the “receiving end” of the Leaf True system and one is required for each
connected “zone” of the Leaf True system.
The LB1 is the breakout that is designed for use with LHDMI66.
3.1 Local Power
Each LB1 breakout is required to be powered by its own (local) power supply and to be
connected via a Cat5e / Cat6 cable link from its HDBaseT port to the associated
HDBaseT port on the LHDMI66. Use only the power supplies that are provided by Leaf
Audio for this purpose.
3.2 Mounting Bracket
Each LB1 is supplied with a mounting bracket which is designed to be attached to the
mounting surface and have the breakout clipped to it.
