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
Ti
p 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.
