Remote MiniBridge, RS-422  

Your link to legacy 10BASE-T Ethernet networks.


1 YEAR DoubleDiamond™ Warranty (Standard)

Product Highlights

  • Incredibly compact, yet fully compatible with IEEE 802.3/Ethernet V.2.
  • Supports full- or half-duplex communication.
  • Sustains WAN link rates up to 10 Mbps sync or 115.2 kbps async.

  • Further Details

  • Automatic aging simplifies management by keeping the address table current.
  • MAC address table automatically learns up to 10,000 addresses.

    Talk about tiny! If our compact Remote MiniBridge were any smaller, you could carry it in your wallet! Use it to connect two legacy 10BASE-T Ethernet LAN segments across V.35, RS-422, or X.21. It's easy—all you have to do is plug it in!

    It configures easily with just four front-panel DIP switches. Once plugged in and powered on, it begins learning the MAC-layer addresses of each node on its segment instantly. Then it goes to work, reducing your overall network traffic by forwarding only those packets bound for other segments.

    The Remote MiniBridge simply plugs into your network hub or switch. Attach the WAN port to a DCE such as a CSU/DSU or multiplexor and you’ve completed your remote connection.

    Filtering and forwarding rates of 14,880 packets per second (pps) approach the theoretical maximum wire-speed threshold of 15,000 pps, so you won’t find a bridge much faster than this one.

    To further support maximum data rates, the internal buffer holds up to 256 frames with a throughput latency of just one frame.

    The comprehensive front-panel LED display conveniently indicates LAN and WAN port activity as well as power (PWR) and collisions (COL).

    Four easy-to-set DIP switches are also on the front of each Remote MiniBridge to help you configure the parameters you need, so you can get to work as quickly as possible.
