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 3rd 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.

output, 1 to 8, left to right.
The LEDS may be off or on in one of 3 different colours corresponding to different
operation modes.
2.3.1.1 GREEN LEDS: DISPLAY MODE.
When the LEDs are green the top row of LEDs indicate the inputs (sources) that are
connected to an output (zone).
The lower row of LEDs indicate the outputs (zone) that are connected to an input
(source).
2.3.1.2 BLUE LEDS: SELECTION MODE.
After a button is pressed the display is in selection mode for a period of time.
CONSTANT: A constant BLUE led indicates a selected input or output.
FLASHING: A flashing BLUE led indicates a pending change.
2.3.1.3 CYAN LEDS: ZONE LOCK MODE.

3.4 IP port
The RJ45 type IP port is a dedicated port for controlling the LTHDMI88/E. This may not
be active on all versions of LTHDMI88 / LTHDMI88E. Further information and
specifications can be found in supplementary documentation available on request from
Leaf.
3.5 RJ12 control port
The 6 wire RJ12 port enables the LTHDMI88/E to be controlled by a proprietary LEAF
controller such as the TC3.
3.6 4 way DIP switch module
The rear panel accessible 4 position DIP switch controls functionality of the
LTHDMI88/E. 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.

3.7 Audio ports
The Stereo Analog and S/PDIF RCA connectors are configured as zone based audio
outputs for connection to local external amplifiers. These provide audio output from the
particular source that is switched to the connected zone at that time.
Note: The Audio Channel Return (ARC) from the zones’ breakout is not currently able
to be routed to these outputs.
3.8 3.5mm IR ports
The 3.5mm Remote IR connectors are used for routing the control signals in one
direction between the LTHDMI88 / LTHDMI88E and the connected LTB1 / LTB1E
breakouts. (See table 2 for DIP switch configuration details.) These connections are
treated as through connections. That is, IR port 1 connects to the breakout on
HDBaseT 1 connection through to port 8 being connected to HDBaseT 8.

Leaf LTHDMI88 / LTHDMI88E manual
Page 10
Of 16
All IR ports support direct connection and drive of 5 volt, 3 wire IR detectors (e.g. Leaf
hammerhead ) to 2 wire IR blasters (e.g. Leaf LB41). The IR ports on the LTHDMI88 /
LTHDMI88E can also be configured (DIP Switches 1 and 2) to accept so called “5 Volt
Tip Ring Sleeve” direct drive IR signals from external control systems. (See table 2 for
DIP switch configuration details.)
3.9 RJ45 type Through RS232 ports
The Remote RS232 connectors are used for routing the associated signals between
the LTHDMI88/E and LTB1 / LTB1E breakouts. Again, these connections are treated
as through connections in a similar fashion to the IR routing with the exception that the
connections are bi-directional, full duplex.
3.10 HDMI Input ports
These standard HDMI input ports are for the purpose of connecting HDMI sources.
They are labelled 1 to 8 reflecting the front panel LEDs from left to right.
All Leaf True systems accord with the HDMI 1.4 specification and includes support of
3D formats.
4 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 LTHDMI88 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. Other manufacturer’s systems may lose video
and or audio for some seconds under similar circumstances. Refer to the Calibration
description in the Operation section for more detail.

4.3 Exclusive Source Selection
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 sink) – even if the 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 LTHDMI88 / LTHDMI88E it will go through a Power Up
routine lasting a minute or two. The display LEDs will cycle blue through all source –
zone connection possibilities in a Right to Left direction.
When this routine is completed the unit will reconnect the most recent Source – Zone
selections and the display LEDs will glow green indicating the switched sources and
zones.
5.2 Calibration.
The system should be calibrated on first use or after any new devices (source or
zone equipment) are added or port allocations changed. 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.
This description is valid for direct access by the front panel mounted buttons and can
also be accessed via RS232 control.
1. Turn on all sources and sinks (receiver or TV). Ensure sinks are set to the
correct HDMI input.
2. Press and hold operated the top button (A) on the front panel for 3 seconds
to commence calibration… or send appropriate RS232 command. The 2
rows of LEDSs will “run” Left To Right alternatively Blue / Green
Page 12
Leaf LTHDMI88 / LTHDMI88E manual
Page 12
Of 16
The calibration process may take up to a minute or two and when finished, the
LEDs will display (green) the previously selected sources and zones.
5.3 Clear all connections / Global OFF
The following steps describe the manual operation required if using the press button
switches on the LTHDMI88 /E. Note that this process is not directly accessible by Leaf
TC3.
Hold the lower button (B) for 3 seconds to clear all connections and set the unit
to standby mode.
Standby mode will be indicated by one single pulsing green/blue LED.
5.4 Creating new input / output connections.
Press the lower button (B) to enter selection mode. THE SELECTION MODE
LEDS WILL BE BLUE.
Press the lower button (B) sequentially until the LED in the lower row
corresponding to the desired output (zone) is blue.
Press the upper button (A) sequentially until the LED in the upper row
corresponding to the desired input (source) is blue.
After a few seconds the connection will be made, and these LEDS will turn
Green.
Notes:
1. If neither button is pressed for an extended time (approx 10sec), the
display will revert back to display mode (displaying input/output
connections).
2. If in the third step above the upper button (A) is pressed until no BLUE
LED are displayed in the upper row, the connection will be cleared - i.e.
the output will be disconnected from the input.
