CHAPTER 5
CABLES AND CONNECTORS
To ensure the proper functioning of a SMART product, use cables that meet the SMART product's
requirements as closely as possible and are tested for compliance with connection standards. The
requirements vary according to the signal type and the distance the signal needs to be
transmitted.
Cable best practices
General best practices
Cables can vary widely in terms of quality and cost, and higher cost doesn't always indicate better
quality. The cable's quality can greatly affect the quality of signals it carries. This becomes
increasingly important as cable runs get longer.
Always use the cables provided with the SMART product. SMART tests these cables against
industry standards and for regulatory compliance. Refer to Appendix B: SMART reliability testing
on page 71 for more information. If you need a cable that is not included, or you need to replace a
cable, follow these general guidelines to help ensure the third-party cables function correctly:
Use cables tested for compliance to connection standards. For example, use HDMI cables
l
that provide proof of being tested against the HDMI standard.
Test cables for continuity. Connect the cable and confirm that the signal is sent and received
l
correctly.
Choose good quality cables from reputable manufacturers.
l
If possible, use cables from a single manufacturer. This is especially important if you're
l
performing multiple installations. It provides greater consistency across the entire installation,
and if you encounter any issues, you deal with only one manufacturer.
