Product Features

  • Details

    Your sync RS-232 devices communicate up to 5 miles (8 km) with the BLACK BOX® SHM-B Sync. For example, if your AS/400 controller and terminal are on different floors—or in different buildings—they can easily talk to each other with a pair of SHM-B Syncs.

    Built-in optical isolation protects your data when you run cable underground or between buildings. Run loopback tests right from the front panel. The flip-open housing makes it easy for you to get inside to connect your 4-wire cabling.
