Electro Standards Laboratories DB9 2-Position Switch Model 4124

Description
Ideal for fallback applications. The switch ports are transparent to all data. All pins of the DB9 interface are switched. Automatic Fallback Mode operates based on data monitoring of pin 3 of the A port and automatic switching occurs after 3 seconds of data loss. All switched signals are passed via latching copper contact relays that maintain their position and continuity in the event of a power loss. Control of the switch position from a Contact Closure Remote Port. Contact Closure allows the user to control switch position, lockout front panel operations and obtain switch status. Front panel LEDs display switch position, the switch mode (automatic fallback or manual) as well as power status. Rugged aluminum case provides EMI/RFI shielding.
