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.
