How to Test Ethernet Cables
All new and current audio equipment will be set up with a way to connect to the Internet, Networks, or a computer. Sometimes a Network connection is only needed so the equipment has a “path” to receive software or firmware changes. Audio technicians must be able to troubleshoot issues with ethernet cables and network cabling connected to audio equipment. Plenty of test equipment is available to assist you (one example shown below). Networking technology is now firmly engraved in the world of audio!
This basic Ethernet Cable Tester is a 2-Piece unit that allows you to test Ethernet cables in from one location to a different location. And obviously tests single cables as well. The unit shown below was purchased for less than $15. Although inexpensive, it worked very well for what I needed.
