These RS-232 and RS-422 TDMs have Built-in Short Range Modems!
 
Model 305x
 
  Features & Benefits
  • Multiplexes 4, 6 or 8 async devices onto two twisted pairs
  • Simultaneous sub-channel data rates up to 19.2 kbps
  • Two-pair distances up to 6000 ft (1.8 km) between multiplexers
  • Support for RS-232 or RS-422 interfaces on modular RJ-45 connectors (D-sub adapter cables available)
  • End-to-end software flow control
  • Hardware (RTS/CTS) flow control (Models 3054 & 3056)
  • Local and remote loopback tests
  • LEDs monitor TD, RD (each sub-channel), link and diagnostics
  • Miniature plastic enclosure fits in tight installation spaces
 
Overview  

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.
