RS-232 Switches

Our user-friendly serial data switches are versatile, intelligent, and allow for seamless communication between your PC and multiple RS-232 devices.


Model 232BSS4, our most versatile and intelligent smart serial data switch. A single RS-232 port on your PC can now communicate seamlessly with four or more RS-232 devices.
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 serial data switch may be connected to PCs or serial devices miles away. Requires 12 VDC power. Model 232PS is recommended.

  • Free set-up 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

Model 232MSS2 is a compact four port mini RS-232 switch box. 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

Each serial data switch has a unique address. A simple serial command from your host turns communications on or off or requests status. QuickBasic demo software is included.

  • Attach a unit to each “dumb” RS-232 device to make it a network node

  • Network up to 32 RS-232 devices up to 4,000 feet away

  • Requires 12 VDC power supply, Model 485PS2 recommended
