The Patton Model 305X Series limited distance multiplexers combine two functions into one handy product. First, each Model 305X Series unit is a time division multiplexer (TDM), multiplexing 4, 6 or 8 individual RS-232- or RS-422- devices onto a single composite channel. Second, each Model 305X Series unit is a short range modem, supporting point-to-point communication at distances up to 6,000 ft (1.8 km) over two unconditioned twisted pairs. All Model 305X Series units support end-to-end software flow control, and are equipped with local and remote loopback tests. (The Model 3054 and 3056 also support RTS/CTS hardware flow control.) In addition, diagnostic LEDs show each sub-channel's status. All data interfaces are ported to modular RJ-45 jacks, and various D-sub adapter cables are available from Patton.
