Price: $503.95




Extended Double Diamond™ Warranty Available (3 Additional Year)

Product Features

  • Time-division multiplexor with an integral short-haul modem.
  • Economical alternative to stat muxes.
  • Four async ports.
  • Details

  • Screw terminal interface on composite port.
  • Support speeds up to 64 kbps per port.
  • Operate at distances up to 3000 feet (914.4 m) over two 24 AWG twisted-pair cables.
  • Plug-and-play installation—no option switches to set.


  • If you're looking for an economical alternative to leased-line modems and statistical multiplexors, the BLACK BOX® Asynchronous Local RS-232 Multiplexor gives you speed and savings in your async environment!

    Here's an economical alternative to more expensive stat muxes.

    Our Async Local RS-232 Mux is a time-division multiplexor that supports 4-channel speeds up to 64 kbps. All ports operate at maximum throughput levels with virtually no multiplexing delay. All models have an internal line driver for twisted pair. The units' internal line drivers provide limited-distance communication over private networks with point-to-point twisted-pair cabling.

    Our Asynchronous Local RS-232 Multiplexor automatically adapts port speeds to the rates of your individual terminals—no clock source is required. Plus, synchronization between multiplexors is maintained automatically.

    NOTE: Must be used in pairs.

    This product works with:
    • CAT5 100-MHz Solid-Conductor Cable, 4-Pair, Straight-Pinned (EYN737MS)
