The Byte Brothers TVR10/100/1000K LAN Tester performs 4 critical tests of hubs, switches, PCs, and cables. It instantly displays device type (hub/switch or PC), speed (10, 100, or 1,000 MB/s; advertised speed), duplex (half, full), and PoE (Power over Ethernet). With inline capability, this easy-to-use tester can test the negotiated speed and PoE. It can also test and trace coax cables via 2 RJ-45/coax adapters.
The lights quickly tell you if the device is a hub/switch or a PC. It reads the link pulse to determine if the device is capable of 10, 100, and/or 1,000 MB/s communication (advertised speed). It displays whether it's half or full duplex. Plus, it detects PoE both endspan and midspan.
Inline capability to go between 2 LAN devices and check the speed and duplex of the link (negotiated speed)
It is also pair tester telling you which pairs are wired and whether they are straight through or crossover.
Can be used as a tone generator. The main unit generates the tone for use by the remote probe.
Test and trace coax cables with the 2 RJ-45/coax adapters.
