Review on 📞 Enhanced Connectivity and Communication: Rosewill RTK 006 Network Ethernet Telephone by Pedro Movie

Inexpensive and does the job well. Don't forget to take a 9 volt battery with you. Normal scanning is fast and good for keeping an eye on the circuit while you play around with it. Slow scanning allows you to detect bad cable connections and/or mixed cables. If you've ever made RJ45 connectors, you know how frustrating it can be trying to fit all the wires into the connectors in the right place. Sometimes you'll swap a pair, and with some wires it doesn't matter to your standard Ethernet port. But Rosewill recognizes crossed pairs if you look for them.
