PathWay® Model 7471R Single Channel DB25 A/B Switch with Automatic Fallback allows the user the capability of switching a MASTER input data channel to either its PRIMARY output data channel or its ALTERNATE output data channel. The Diagram shows the DB25 COMMON device (Master input channel) can swttched to DB25 A (Primary Output Data Channel) or DB25B (Alternate Output Data Channel).
FEATURES:
- The unit may be switched manually, or automatically.
- Local Manual Control via three front panel pushbuttons:
(1) “AUTO” for Auto Fallback Mode: (1) “PRIMARY” for switch position A. (1) “ALTERNATE” for switch position B.
- When in “AUTO” mode, CTS (pin 5) is monitored on both ports A (PRIMARY), and B (ALTERNATE).
- Three front panel LED’s indicate switch position and power.
- (1) Green LED labeled “AUTO”, (1) Red LED labeled “PRIMARY”, and (1) RED LED labeled “ALTERNATE”.
- Pins 2 thru 6, 8, 15, 17, 20-22, and 24 are switched.
- Pin 1 (Protective Ground) on A, B, and COM, are tied together.
- Pin 7 (Signal Ground) on A and B are tied to Board Ground for reference when monitoring signal.
- When in Auto Mode, CTS (Pin 5) is monitored on Ports A (Primary) and B (Alternative).
- All in/out ports are located on rear panel.
- All switched signals are passed via latching copper contact relays that maintain their position and continuity even in the event of a power loss or failure.
- When power is restored, unit loads previous position and mode of operation and checks DIP switch settings to determine the correct startup configuration.
- RoHS Compliant
