Black Box SM265A Gang Switch - 2U RS232/DB25 A/b Card Latching
Overview
The Black Box SM265A is a 2U rackmount gang switch designed to manage multiple RS-232 serial devices through a single DB25 A/b interface. This unit is critical for environments that require the integration of legacy serial equipment into modern networked systems, providing a centralized point for switching serial data paths. Its latching mechanism ensures a stable connection once a path is selected, preventing accidental disconnections in critical applications.
Compatibility
This switch is designed to interface with RS-232 serial devices that utilize DB25 connectors. It is suitable for use with a wide range of serial communication equipment, including modems, terminals, and industrial control systems. The SM265A is intended for direct serial data path management, not for network data traffic.
Installation Notes
Installation requires connecting RS-232 serial devices to the A/b ports and the desired control interface to the DB25 connector. Ensure proper torque is applied to all connections to maintain signal integrity. The unit is designed for standard 19-inch rack mounting.
