TIA568 Wiring Standards

How to decide which wiring pattern to use:

1. Does the job specification call out a wiring pattern?
2. Does the customer/end user have a preference for T568A or T568B?
3. Have patch panels already been purchased for the job? If so, they will probably be either T568A or T568B. The jacks should be wired to the same pattern as the panels.
4. Are you adding on to an existing wiring plant? If so, your new wiring should match the existing wiring.

If none of the factors above apply, either T568A or T568B may be used. It is important to ensure that the workstation connectors and the patch panels are wired to the same pattern. T568B is commonly used in commercial installations, while T568A is prevalent in residential installations.

Intelix DIGI-VGA-F High Resolution VGA Balun


Intelix DIGI-VGA-F High Resolution VGA Balun

Intelix DIGI-VGA-F High Resolution VGA Balun

Install Manual & Tech Specs

The Intelix DIGI-VGA-F balun set transmits high-definition VGA video and high fidelity analog audio extended distances over inexpensive structured pair cabling, such as Cat 5 or Cat 6. The DIGI-VGA-F balun set includes a DIGI-VGA-S-F send balun, a DIGI-VGA-R-F receive balun, two power supplies, and a USB power cable. The kit is powered on both the send and receive end with either 12 VDC power supplies or optional USB power on the send end. The send balun provides local audio/video outputs for added versatility, whereas the receive balun features dual amplified audio/video outputs for linking. In addition, the DIGI-VGA-R-F receive balun provides brightness, contrast, and overall picture quality adjustment for skew free performance over standard Cat 5 cabling.
