New Automatic Fallback Switch Affords Complete Remote Control Functionality
The new Model 4133 DB25 A/B auto fallback switch senses data activity on port A and switches to port B when activity on A is lost. This versatile switch can be controlled remotely via ASCII commands or via front-panel pushbutton.
- (1888PressRelease) February 28, 2013 - Electro Standards Laboratories, Cranston, RI, USA, announces the new PathWay Model 4133 single-channel DB25 A/B switch with auto fallback and RS232 remote control. The switch enables sharing a single port interface device connected to the COMMON port among two other devices connected to the A and B ports.
The Model 4133 is controlled locally via a front-panel pushbutton or remotely via the DB9 female serial interface Remote port. The front-panel LED display indicates the switch position, switch mode and power status.
This switch monitors data activity on port A. If the unit is in the A position and activity is lost for the duration of the set delay time, the unit automatically switches to the B position. The unit will remain in the B position until commanded to switch to the A position either manually or remotely.
The Model 4133 maintains the last set position on power loss and continues to pass data. The remote RS232 ASCII commands allow the user to control the switch position, lockout the front-panel operations, change modes, set the delay time and obtain switch status.
