control used by external control devices attached to a PureLink device. Command codes
are used primarily for control, during system installation, setup, and for diagnostic
purposes.

Command code is a set of alphanumeric characters that combine to form control
commands. Command code strings are entered into a terminal emulation program (such
as windows HyperTerminal) running on an external control device. The control device
(PC, third-party controller) sends the commands to the system. Control devices must be
able to send and receive ASCII or HEXA code via an RS-232.

1-9 Troubleshooting

Problem

Solution

Distribution Amplifier
does not operate

Make sure the 12V power is plugged in the back of the unit.
Check to see if the power LED light is on.

No picture(or signal)
Or Poor picture

1. In case your video source is HDCP enabled, make sure
your video display (HDTV) is HDCP compliant.

2. If you are using copper based HDMI cable, overall length
of the cables (length of the cable from video source to
switch and length of the cable from switch to display)
should not exceed 20ft. Exceeding 20ft. with copper based
cables will result in no or poor picture quality. To extend
beyond 20ft, please use fiber optical HDMI extension cables
such as PureLink EZ series.

3. Use high quality HDMI cables.

4. If you are using computers, try other refresh rate

settings. Most HDTV’s have refresh rate of 48Hz and
computer’s video cards are usually set at higher refresh

rate. Try lower refresh rates.

5. Make sure all HDMI connectors are tightly secured to all
HDMI ports. Loosened screws on the HDMI connectors will
result in no or poor picture.

6. Turn off all equipment (video source, switch and HDTV)
and restart all equipment.

Incorrectly sized picture
/resolution or No picture

Please remember that your video source will only transmit
one resolution setting. To connect varying resolution
displays (1920x1200 resolution display and 1024 x 768
resolution display) the resolution setting of your video
source must be set to the lowest resolution setting (1024 x

768).
