CAT5 is widely used to make HDMI cables and transmit HDMI cable data.

High definition multimedia interface (HDMI) cables employ 19 individual connectors. In addition, the tools and user-serviceable end pieces are not readily available. For those wanting to make HDMI cables from Category 5 Ethernet-style cables, the solution lies with baluns. These are devices that alter the wiring pattern of two CAT5 cables, converting them internally to HDMI. Although a couple of short HDMI cables are needed, the use of CAT5 and baluns solves the problem of long runs and a slim profile.


Step 1

Access the rear panel of the HDMI-equipped component serving as the source. Find the HDMI port.

Clip one end of two CAT5 cables into the sending balun. Route the CAT5 cables to their destination, and clip the other ends to the receiving balun.


Step 4

Plug a short HDMI cable from the receiving balun to the receiver or display.

Step 5

Plug the supplied AC power adapter into either the sending or receiving balun.
