The PathWay® Model 4145 Automatic Fallback and Recovery DB25 A/B Switch with Optional RS232 Remote Control allows the user the capability of sharing a single port interface device connected to the "COMMON" port among two other devices connected to the "A" and "B" ports, with remote access functionality. The Model 4145 is packaged in a slim desktop style enclosure.
The switch may be controlled locally by manually operating the front panel pushbutton, or remotely through the DB9 Female Serial Interface Remote port located on the rear panel of the unit. (If the Remote port has been ordered). The front panel LED display indicates the switch position, switch mode, and power status.
The unit monitors data activity on port "A" for carrier presence (DCD) signal on Primary line Port A. If the unit is in the A position and activity is lost, the unit automatically switches to the B position. When carrier is detected on Port A, the unit will automatically return to the A position.
