Electro Standards Laboratories (ESL), Cranston RI, has just announced its new Model 4135 Single Channel DB9 A/B Switch.  The Model 4135 allows sharing a DB9 device connected to the COMMON port connector among two other devices connected to the A and B ports.

The switch may be controlled locally via pushbutton or remotely from a remote toggle switch connected to the DB9 female interface Remote port.  The Remote port is contact closure enabled to switch between A and B. The Remote port overrides pushbutton activity.

Front Panel LED display indicates switch position and unit power status. The switched set of ports, A, B, and COMMON are transparent to all data. The Model 4135 retains the current switch position and maintains continuity through the switch even if power is removed or a power failure occurs.
