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.

The LTHDMI88E front panel is identical except for the addition of an additional row of 8 x RJ45 type ports for Ethernet connection.

2.1 HDBase T Connections

Each Leaf True breakout is connected to the interface by way of a single Cat5e/6 cable to the HDBaseT output or zone ports across the lower part of the front panel.

2.2 Ethernet Ports

The Ethernet ports across the upper part of the front panel of LTHDMI88E are for connection of Ethernet facilities for direct routing to remote Ethernet ports at each LTB1E breakout.


The Ethernet connection is 100Base-T full duplex. An external Ethernet router / switch may be added for added flexibility and performance.

2.3 Front Panel LED display and selection buttons

16 dual colour (green / blue) Light Emitting Diodes(LEDs) and 2 press button switches are fitted at the right hand end of the front panel.

The top row of LEDs is associated with the 8 inputs (sources) with one LED for each input, 1 to 8, left to right.

The lower row of LEDs is associated with the 8 outputs (zones) with one LED for each 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).

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.

Table 2: 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.


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


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.
