Electro Standards Laboratories RS232/RS530 A/B Switch Model M7276

Description
Switch to backup automatically via Data Activity or DCD trigger monitor. Switches back when signals restore. The switch ports are transparent to all data. All pins of the DB25 interface are switched. All switched signals are passed via copper contact relays that maintain their position and continuity even in event of power loss or failure. When power is restored, the unit loads previous position and mode of operation and checks DIP switch settings and remote port to determine the correct startup configuration. Automatic switching based on either RD activity or DCD presence. Automatic switching compatible with RS-232 or RS-530 protocols. Remote control of the switch position from a contact closure REMOTE port. Reading of the current switch position from a contact closure remote port. Front panel LED's display position, mode and power status.
