1 Introducing the Leaf True LHDMI44P
1.1 Overview
The Leaf True HDMI Matrix LHDMI44P package comprises a Leaf LHDMI44 interface
unit and four Leaf LB1 breakouts. It is designed to accept HDMI A/V sources at its
inputs on the LHDMI44 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 LHDMI44 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 LHDMI44. See 5.3 - 5.4 for details. A
corresponding set of display LEDs provide user feedback of the signal routing.
The LHDMI44 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.

2.3 3.5mm IR ports
The 3.5mm Remote IR connectors are used for routing external IR control signals in
one direction between the LHDMI44 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
LHDMI44 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 LHDMI44.

Leaf LHDMI44 manual
Page 8
Of 19
The “Ring” connection of these leads at the LHDMI44 end (or both ends) must be left
“floating” / not connected.
(See table 2 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 LHDMI44 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 LHDMI44 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
LHDMI44. 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 LHDMI44 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 LHDMI44 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

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 4.
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 LHDMI44.
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
HDBase T port on the LHDMI44. 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.

Leaf LHDMI44 manual
Page 11
Of 19
3.3 Status LEDs
A set of 3 Status LEDs are visible through apertures in the right hand side of the LB1.
The Status LEDs operations are:
LED 1 FLASHING (heartbeat) = The local 12V DC power supply is
connected and active.
LED 2 ON = The HDBaseT Cat5e / Cat6 cable link to the LHDMI44 has
been made successfully and is ready for video.
LED 3 ON = Protected (HDCP) video content is being transferred on the
HDBaseT link.
FLASHING = Non protected (no HDCP) video content is being
transferred on the HDBaseT link. Irregular flashing may indicate an
issue with the video link.
OFF = No video content is being transferred.
(Usually means that no source has been selected for that zone).
4 SYSTEM FEATURES
4.1 EDID Management
The Extended Display Identification Data (EDID) of all sinks (TVs, Display Panels, etc)
attached to a zone are merged and presented to the source. This ensures that the
source outputs the correct audio and video format to all sinks .
When a sink is switched to a source the LHDMI44 remembers its EDID. After a
calibration, or each time new sinks are switched, the combination or merge of this sink
EDID and previously switched sink EDIDs is calculated and stored for use thereafter
until power off or recalibration.
This guarantees true repeater functionality while minimising interruption to active TVs
or Display panels when selecting sources.
4.2 Calibration
This process effectively gathers all of the information from the source and sink devices
(EDID and HDCP keys data) and pre-calculates the EDID merging and HDCP key list.
This results in faster switching times and isolates the effect on one zone from another
zone when new connections are routed. Refer to the Calibration description in the
Operation section for more detail.
LEDs 3, 2, 1.

4.3 Exclusive Source Selection (Zone Lock mode)
A source can be locked to a particular zone. The exclusive source selection feature
enables enhanced features, such as multichannel audio, 3D etc, to become active
in the locked zone (if supported by both the source and zone equipment) –even if
other zones in the system do not support these features.
This feature is activated by RS232 command.
Any one zone can be locked to a desired source thus creating a so-called
“locked connection”.
Effectively this feature overrides the system merged EDID for this connection
and allows the unique EDID for the zone to be passed through to the source. A
typical example would be switching a 3D-capable zone to a 3D-capable source
in instances where not all zones in the system can support 3D.
No other zone can connect to a source that is locked.
Multiple locked connections are allowed but locked sources cannot be shared.
When the zone of a locked connection is disconnected the source is unlocked
and available for selection by other sources.
When the zone of a locked connection changes to a new source the existing
source is unlocked.
When a global command is sent then the existing source is unlocked
Locking a zone to a source that is already switched to one or more other zones
will cause that source to disconnect from those zones.

5 Operation
5.1 Apply Power
Once power is applied to the LHDMI44 it will go through a Power Up routine lasting a
minute or two. The display LEDs will cycle blue in a Right to Left direction.
When this routine is completed the unit will reconnect the most recent state (Source –
Zone selection or standby) The display LEDs will glow green indicating the switched
sources and zones.
The left hand four LEDs indicate input sources 1 to 4, left to right.
The right hand four LEDs indicate output zones 1 o 4 left to right.
Standby will be indicated by the right hand LED only, pulsing green/ blue.
5.2 Calibration
The system should be calibrated on first use, after any new devices (source or
zone equipment) are added, port allocations changed or after power has been
interrupted and reapplied. Failure to correctly calibrate a system may lead to
interruption to audio and video at zones when other zones are switched to a
source that is already in use.
The system may be calibrated under RS232 control or manually by following
these steps.
1. Turn on all sources and zone equipment (receiver or TV). Ensure that zone
equipment (TV’s etc) are set to the correct HDMI input.
2. Press and hold operated the left hand press button switch on the front panel
for 3 seconds to commence calibration.

Leaf LHDMI44 manual
Page 14
Of 19
The LEDSs will “run” Left To Right alternatively Blue / Green
The calibration process may take up to a minute or two and when finished, the
LEDs will display (green) any previously selected sources and zones or revert
to standby (right hand LED only, pulsing green/blue) if that was the previous
state.
5.3 Creating input to output switched selections
While this would typically be performed by RS232 commands from your control system,
basic selections may also be performed manually by following these steps in
sequence.
Manually select output zone
Press the right hand press button switch sequentially until one of the right hand four
LEDs corresponding to the desired output (zone) is blue, then release the switch and
proceed to the next step.
The right hand four LEDs indicate the output zones 1 to 4 left to right.
(Zone 2 is depicted in this picture)
Manually select the input source for that Zone
Press the left hand press button switch sequentially until one of the four left hand LEDs
corresponding to the desired input (source) is blue, then release the switch.
The left hand four LEDs indicates the input sources 1 to 4 left to right.
(Source 1 is depicted in this picture)

Leaf LHDMI44 manual
Page 15
Of 19
After a few seconds the switched selection will be made, and these LEDS will
change to Green.
Repeat this process for other input (source) to output (zone) selections as required.
Notes: 1. If neither button is pressed for an extended time (approx 10sec), the
display will revert back to display (green) mode, displaying the existing
input/output connections.
2. If in the second step above the left hand press button switch is pressed
until no Blue input LEDs are displayed, the connection will be cleared -
i.e. the output will be disconnected from the input.
5.4 Clear all switched selections / Global OFF
While this would typically be performed by RS232 commands from your control system,
it may also be performed manually by the following steps.
Press and hold the right hand press button switch for 3 seconds to clear all switched
selections and set the unit to standby mode.
Standby mode will be indicated by the right hand LED only, pulsing green / blue.
