I provide support for a police station who uses a system that comes in over a coax cable, and is then split out 4 or 5 ways via an old ibm coax hub. The coax cable then run directly to various workstations and into an attachmate 3270 coax card. Using Terminal Emulation, they are able to connect to the application. I'd like to get some input on what the most effective way to go about converting that coax signal to rj45 and running it to the workstations over ethernet. Is there some kind of hardware that I'd need to buy?
