Chapter 5: Hardware Installation
5. Hardware Installation
1. Connect an HDMI or VGA input source (such as Blu-ray™) to the VX-1002-TX
transmitter.
NOTE: Be careful when connecting cables—do not force the cable ends into the
connectors.
2. Connect a good quality, well-terminal CAT5e/6 cable of no more than
230 feet (70 m) for 4K or 328 feet (100 m) for 1080p from the HDBaseT OUT
port of the Transmitter to HDBaseT IN Input of the HDBaseT receiver.
NOTE: 230 feet (70 m) @ 4K or 328 feet (100 m) @ 1080p video are maximum
recommended transmission distances for this model and denote perfect
transmission conditions—including straight cable runs with no electrical
interference, bends, kinks, patch panels, or wall outlets.
If either of the above is a factor in your installation, transmission range may be
affected—avoid where possible.
3. Connect an HDMI display device (LED/LCD display or projector) to the HDMI
OUT port on the HDBaseT receiver.
4. Connect the IR emitter cable to the IR OUT port of the VX-1002-TX, connect
the IR receiver cable to the IR RX port of the receiver, and connect the IR
emitter to the IR TX port of the receiver.
5. Power on the HDBaseT receiver. If the HDBaseT receiver doesn't support the
PSE function, connect a 12 V power supply to the VX-1002-TX transmitter.

Chapter 6: Troubleshooting
6. Troubleshooting
The majority of HD distribution installation issues are either caused by minor
connection errors, communication problems between devices, or when the
transmission of high signal bandwidth is attempted using insufficient cable.
If you encounter any technical difficulties when installing and configuring the
matrix, refer to the following troubleshooting checklist. If you cannot resolve
your problem, contact Black Box Technical Support at 877-877-2269
or [e-mail].
Problem: No picture or poor-quality picture.
Possible Solutions:
1. Power—is your transmission device and receiver powered with correct LED
indication?
2. If possible, always use test equipment before installation and to troubleshoot
any problems.
3. Check that the display device supports HDCP, is switched to the correct
source input mode, and is compatible with the receiver—if you suspect any
issues, replace the display device with another model.
4. Distance—Is the cable too long for the signal to be transmitted effectively?
Make sure the cable distance matches the project requirements and is well
within the maximum transmission distance of the signal.
NOTE: If you need more distance than the transmitter can provide, use another
extender set to be sure that the signal reaches its destination effectively.
5. Cable joins—Joins in the cable run or RJ-45 connectors can impact signal
strength, resulting in reduced transmission that may manifest itself in
incorrect picture quality, picture dropping out, or no picture.
6. Cable choice and signal reduction—Are stranded patch leads used as
interconnects between patch panels or wall outlets? CCA (Copper Clad
aluminum) cables being used? These can reduce transmission rates by up to
40%—we recommend solid-core straightthrough cables with minimum con-
nections used wherever possible.
7. Correct connection— Double-check that all UTP, HDMI, power and IR cables
are connected to the correct ports.
NOTE: Even a fraction off target can make the difference between a perfect
picture and a blank screen. Double-check all connections are firmly made
in the correct ports.

877-877-2269 | blackbox.com Page 19
Chapter 6: Troubleshooting
8. Is the cable wired to 568B standard? Is the cable wired and terminated
correctly and are those terminations connected to the correct ports? Incorrect
wiring and termination will result in unstable operation or a blank screen.
9. Electrical interference—could any form of interference be generated? If so,
attempt to remove the source of electrical interference or move the cable run
to decrease the effects of the interference.
10. Is a picture displayed when connecting the source directly to the display? If
not, then the problem could be with the input or output device rather than
the cable or matrix itself.
11. HDMI lead condition and quality—HDMI cables and connectors are delicate
and can be damaged much easier than component or coax cable. Lead
quality varies dramatically, particularly in lower price brackets. Swap HDMI
leads and check operation—damage to or quality of your leads could be
the problem. If in doubt, swap them over. Be careful when inserting
and extracting your HDMI from matrix ports so you don’t damage the
connectors or ports.
12. Picture speckles/HD “noise”— A poorly established signal that may be
caused by poor quality or excessive HDMI cable lengths. Try swapping the
display adapters from a location that is functioning properly or swapping the
outputs of the matrix switch used.
If the problem remains on the same screen, this may be caused by a
connection problem between matrix and display—turn off all equipment
and swap the signal carrying cables at both ends to determine if the cable
or termination is at fault.
HD Noise (NO image) may be an HDCP Issue between the source and dis-
play, but poor cabling can also cause this via poor communication.
13. Blu-ray: 3D—Is the equipment used 3D enabled/compatible? Is a 3D disk
playing in a 3D-enabled Blu-ray player or through a compatible AV receiver?
14. Color distortion—a pink or green screen indicates an incompatibility
between color spacing formats —the commonly used RGB or YUV used by
older displays. Some sources allow switching between RGB and YUV which
may solve any color problems. If not, change the HDMI cable between the
source and the matrix to rule out defective cabling.

877-877-2269 | blackbox.com
Page 20
Chapter 6: Troubleshooting
Problem: No sound or poor-quality audio.
Possible Solutions:
Audio is transmitted within the video signal—there is no separate audio track—
so a problem with sound will be accompanied by a problem with picture. But
you might have technical issues with audio caused by problems communicating
between sources, displays, and/or AV receiver settings.
1. Have specific speaker sets or zones been enabled? Some AV receivers allow
individual speaker selections assigned to specific zones in the set up so check
the speakers used are fully connected to the amplifier and correctly assigned
within the system set up. An EDID issue might occur when the source reads
the audio EDID from the display and only requests two-channel audio. You
might need to copy EDID from the AV receiver or use an embedded EDID in
the AMP or matrix.
NOTE: If you have problems when using an AV receiver, the cause is usually
the settings of the AV receiver itself. Refer to the AVR manufacturer’s
guidelines for the correct settings to use for your requirements.
2. Consistency of audio output between devices—Is there any discrepancy
between the audio output of the source, the audio or zonal settings of the
AV receiver, and the speaker configuration used needed for successful audio
replication? If outputting 7.1, make sure all devices connected are also
outputting 7.1.
NOTE: Some source device settings might allow audio output through a TV
or an HDMI port. If using an AV receiver, be sure to select the HDMI
output option.
3. Do all the local sources work through the AV receiver? Check the operation
of each source individually.
4. Bandwidth—If using a graphics-based source (such as a PC/Mac/
media server), make sure the source resolution is set to a maximum of 1080p,
50 Hz. Higher resolutions available for graphics-based systems require higher
bandwidth that may affect transmission of signals as well as incompatibility
with devices.
