FAQ:
Q: What is a serial to Ethernet?
A: A serial to Ethernet converter is an electronic appliance that is capable of converting data packets received over the TCP/IP network into serial data signals and back. The converter redirects a serial device across the network, thus eliminating the need for its physical connection to a computer.
Q: What do you use an Ethernet adapter for?
A: An Ethernet cable. Every Ethernet network adapter has a jack that accepts a cable, which carries the data. The cable connects a computer to networking hub, switch, or router. The cable may be made of copper wires or fiber optic cables; typically, fiber optic Ethernet network adapters are only used in special cases.
Q: How do you connect an Ethernet cable to a TV?
A: Connect the cable running from inside the wall of your home to your cable modem’s input port. This is the cylindrical threaded port much like the main port on the TV set. Plug an LAN Ethernet cable into one of the output ports on the modem. Connect the same cable to the LAN input port on your TV set.
Q: Is there a splitter for an Ethernet cable?
A: An Ethernet splitter takes advantage of the fact that 10MBit and 100Mbit Ethernet only use 4 wires, even though the cable (almost certainly) contains 8 wires. The splitter consists of two pieces (see picture): one is connected to each end of the existing cable, providing the appearance of two ports at each end.
