Model 7300 Single Channel RS232 / RS530 A/B Switch with Fallback & Remote Control Port

The PathWay® Model 7300 Single Channel RS232 / RS530 A/B Network Switch with Fallback and Remote Control Port 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 remote port can be used to attain switch position status by using the provided set of contact closure pins. The remote port can also be used to control the switch position and mode using a separate set of contact closure pins.

When in automatic fallback mode the unit monitors either RD activity or DCD presence on port A only. If activity or presence of the selected trigger signal (RD or DCD) is detected on Port A, the unit switches to the A Position and stays in this position while there is still activity or presence detected. If activity or presence of the selected trigger signal (RD or DCD) is detected on Port A, the unit switches to the B Position and stays in this position until activity or presence is detected on Port A. The user can override automatic fallback operation from the front panel or remote port and force the unit to operate as an A/B switch.

Features:

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 RS232 or RS530 protocols.
Remote control of the switch position and mode 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.
