Status Indicator Lights:
There are two light-emitting-diode (LED) indicator lights. These show
the connection status as described below:
- ACTIVE: On if the external 5-VDC power is supplied, and HDMI
“Standby Power” is active.
- VIDEO: On if the ACTIVE light is on, and the video input signals
are actively driven.
Both indicators must be illuminated for the HDMI-HDMI extender to
pass video/audio. However, having both indicators illuminated does not
guarantee that video/audio can be passed, or that the desired resolution
can be achieved for the system as configured. The lights indicate that
power is applied, that the source’s “standby power” is active, and that
the video input signals are being driven, and not that video is being
correctly received.
Input Equalization Selection:
The input-equalization (Input-EQ) rotary switch has settings from 0 (no
Input-EQ) to 7 (maximum Input-EQ). For short input cables, set input-
EQ to 0. Input-EQ settings range from 0 – 2 for up to 5 meters, 1 – 4
for 5 to 10 meters, and 2 – 7 for = 10 meters.
For best performance multiple switch settings should be tested and the
average of the working settings should be used.
After the Input-EQ setting has been selected, power down the system
and then power on normally to test that the video signal “locks” at
power on. Acquiring signal “lock” is harder than maintaining “lock.” A
setting that works while changing Input-EQ settings may not “lock”
during power-on. While unlikely, if this occurs, try other settings and
test for power-on signal “lock.”

Setup Tips and Trouble Shooting:
- For long HDMI cables, it is recommended that HDMI 1.3 22 AWG,
or better, cables be used.
- Avoid bundling the HDMI cables with LAN and other digital cables.
- If the system is properly connected with quality cables of an
appropriate length, and equipment is turned on, if no video is seen,
the likely cause is the Input-EQ is not properly set for the given cable
type and cable length.
- If video is absent and all connections have been made, and system is
on, one trouble shooting method is to temporarily connect a shorter
HDMI cable directly from the source to the HDMI-HDMI extender
with the Input EQ set appropriately. This may help identify the long
HDMI cable as an issue or eliminate it as the problem.
- Cable type, source-device clock-jitter, sink-device jitter-sensitivity,
intra-cable crosstalk, inter-cable crosstalk, cable bundling, and
ground loops, determine, and limit, maximum reliable cable length.
- HDMI audio is more sensitive to cable jitter than video. So, the
maximum cable length may be reduced if audio is being used.
Specifications:
- Maximum pixel clock rate: 300 MHz (3 GHz bit rate per channel),
which support up to 1080p120, or 1080p60 with 16-bit 4:4:4
- Maximum video rate using HDMI 1.3 22 AWG HDMI input cable,
for nominal conditions is:
For 1080p60 with 12-bit 4:2:2, or 8-bit 4:4:4: 30 meters
For 1080p75 with 12-bit 4:2:2, or 8-bit 4:4:4: 30 meters
For 1080p120 with 12-bit 4:2:2, or 8-bit 4:4:4: TBD
For 1080p60 with 16-bit 4:4:4: TBD
- Maximum distance may be reduced if audio is used since HDMI
audio is more sensitive to cable induced jitter than video.
- Supports all HDMI 1.4 3D formats and the HDMI 1.4 Audio-Return-
Channel (ARC).
- Two HDMI-HDMI units can be placed in series, with long HDMI
cables between the units, to increase the total achievable distance.
- Power: 2.5 Watts
