Securing the HDMI Connector
Follow these instructions to secure the input and output connectors to the distribution
amplifier with the LockIt HDMI lacing bracket provided:
1. Plug the HDMI cable into the rear panel port (
1
) .
2. Loosen the HDMI connection mounting
screw from the panel enough to allow the
LockIt lacing bracket to be placed over
it
(
2
)
. The screw does not have to be
removed.
3. Place the LockIt lacing bracket on the screw
and against the HDMI connector, then
tighten the screw to secure the bracket (
3
).
ATTENTION:
• Do not overtighten the HDMI
connector mounting screw. The
shield it fastens to is very thin and
can easily be stripped.
• Ne serrez pas trop la vis de montage
du connecteur HDMI. Le blindage
auquel elle est attachée est très fin
et peut facilement être dénudé.
4. Loosely place the included tie wrap around the HDMI connector and the LockIt
lacing bracket as shown (
4
).
5. While holding the connector securely against the lacing bracket, tighten the tie
wrap, then remove any excess length.
Connecting Output Displays
D
HDMI outputs
— Use an HDMI cable to connect up to six output displays to the
female HDMI ports on the rear panel (see
figure 2
,
D
on page 6).
NOTE: Secure the input and output connectors to the distribution amplifier with
the provided LockIt HDMI lacing bracket (see Securing the HDMI Connector).
By default, the EDID is set to 1080p @ 60 Hz with 2‑channel audio. However, EDID
can be changed by using PCS (see
EDID Minder on page 21). There are two, four,
or six slots that are automatically populated by EDID from connected sink devices.
The DA monitors the EDID of each connected display to ensure compatibility with the
input signal. The following adjustments are made for each output independently:
•
Interface format — If the connected display is DVI and the input signal is HDMI,
the signal is reformatted to DVI. If the output is HDMI and the input is DVI, no
reformatting is needed because HDMI is backwards compatible with DVI.
•
Video color bit depth — The signal can be forced to always truncate to
8‑bit, disabling deep color, via SIS commands (see Video Color Bit Depth on
page 29) or PCS (see Output Configuration on page 20).
•
Audio — If the connected output device does not support the audio format of
the input signal, audio is muted.
If the source requires HDCP encryption and the display is not HDCP compliant, that
output channel outputs a green screen.
All outputs carry +5 VDC and up to 250 mA on pin 18, regulated by a current limiting
circuit.
