Simplify your RS-232 connections with a smart switch

  • Network your RS-232 peripherals using only a single serial port from your PC.
  • Smart switches simplify multiple RS-232 connections.


  • Marcus' Notebook: Connect up to 17 devices to one serial port

    Often called “line sharers” or “code-activated switches,” B&B Electronics’ smart switches can be used to connect one RS-232 port to four or more different serial devices. These switches can be controlled in two different ways.

    The first way is referred to as “smart switch mode.” In this mode, the switch is controlled by sending a preamble (usually three characters) to the master port. One character of the preamble code is user programmable by internal switch settings. As soon as the preamble code is received, the selected slave port is connected to the master port.

    The second way the switch can be controlled is referred to as “port combiner mode.” In port combiner mode, a slave port can gain access to the master port by asserting a handshake line (RTS for DTE slave ports, CTS for DCE slave ports). If none of the slave ports have their handshake line asserted, the switch can be controlled using the preamble codes. There is no delay through non-buffered switches. LEDs indicate which port is selected.

    Serial Data Switches

    Model 232BSS4, our most versatile and intelligent smart switch, ships with Vlinx Q4, B&B Electronics’ serial network management software. It provides visualization-mapping and helps set up your network of RS-232 devices with a few keystrokes. A single RS-232 port on your PC can now communicate seamlessly with four or more RS-232 devices.

    Vlinx Q4 software configures ports and assigns a Windows COM port within Windows 2000 or XP. Once configured, simply run your existing application software to converse with each device as if it was directly wired to your PC.

    When used with B&B Electronics RS-485 or fiber optic converters, the Model 232BSS4 smart switch may be connected to PCs or serial devices miles away. Requires 12 VDC power.

    • Free networking software included for XP, 2000
    • User friendly graphic interface
    • Configure each port individually from your PC
    • 8 KB buffer on each port ensures no lost data
    • Connectors: master DB25 female, slaves DB9 male
    • Mix and match baud rates
    232MSS2 - Compact Four Port Mini Switch

    Model 232MSS2 is a compact four port mini switch. Its master port may be configured as either a DTE or DCE port. If the master port is DTE, the four other ports automatically become DCE ports. This model offers enhanced features that automatically control transmit/ receive functions, stop inadvertent switching from binary/graphic file transfers and inactive slave devices from holding control of the master port.

    • 4 RS-232 DB9 female slave ports
    • Automatic transmit and receive control
    • Supports 1200 to 115.2 kbps
    • Requires 12 VDC power supply
