GENERAl TROuBlESHOOTING
PROBLEM
POSSIBLE SOLUTION
NO IMAGE
•
Check if connection to the source and the display are correct.
•
Ensure that display device supports 480p, 720p and 1080p 4K@30 resolution
•
Terminated to 568B standard with Shielded Ends Recommended
•
High Quality CAT5/6/7 Cable helps signal transmission
•
please use the supplied power supply-DC 24V 2.7A
•
Check lED link light see (Section 3 panel Description)
•
Check lED Sync light see (Section 3 panel Description)
EDID ISSUE
•
EDID MODE-TV: The default factory setting is on TV. The unit will detect the
1st CAT5e/6/7 output’s EDID. When obtained a (4K2K) ultra HD 3840x2160
EDID the signal is transmitted.
•
If the 1st CAT5e/6/7 output is without a ultra HD 3840x2160 EDID the unit
will detect all output’s EDID and Transmit the signal that all outputs can accept.
•
EDID MODE-STD: Switch to STD to use built-in EDID if the display has No
Image. STD EDID’s video at 1080p@60Hz and audio at lpCM 2CH.
SET-TOP BOX
NO PICTURE
•
HDBaseT and HDMI 1.3 standards support ClOCK STRETCHING for i2c
buss protocol
•
Example set top boxes like Scientific Atlantic results no picture. This can be
resolved by swapping out the box for a newer version that supports HDMI 1.3
not HDMI 1.2
NO INFRARED
COMMUNICATION
•
Ensure the uTp cable is run within the wall away from EMI and High Voltage
power lines.
•
please check manual of device to ensure proper placement of IR Blaster on IR
EyE.
•
Some lED /plasma TV have EMI interference with the IR Extender, please
place the IR Rx 3-6” away from Screen
Recommended TEST
END-TO-END TESTING
HDBaseT system, a final end-to-end test of all the A/V components should take place.
These tests include checking the HDMI stream at the far end (sink end), the clock
rate, frame compare, video pattern, audio, EDID and HDCp with Quantum 780
(recommended)
PASSIVE MONITORING
passive monitoring enables an integrator to view the HDCp transactions, EDID
exchange, as well as the connection events between the actual devices in the network.
