  3. Connect equipment up to 100 feet (30.4 m) apart.
  4. Provides clocking to both DTEs.
  5. Operates in either sync or async modes.
    　

    6. 　

    Further Details

  6. Runs at 38.4 kbps.
  7. Operates full- or half-duplex.
  8. Has two DB25 connectors and six LEDs (TX, CTS, and DSR for each of the two ports).
    We’ve tailored our SME-4M for your IBM equipment. Use it to regenerate the RS-232 signals, so you can send data up to 100 feet (30.4 m). Then you can put your sync (or async) devices where you want them.

    Use the SME-4M to provide clocking to your system, instead of a pair of modems or line drivers to connect controllers or other systems to your front-end processor. You can monitor the operating status easily with a glance at the front-panel LEDs.

    Because the SME-4M is so small and lightweight, it minimizes logistics problems and simplifies installation and replacement in the field. No special tools are required either. It’s definitely designed for do-it-yourself installation.
