Black Box Pro Switch 2U Switch Card RS232 DB25 A B

Switch between two RS232/DB25 connection with signal monitoring for TXD, RXD, RTS and DCD. Pick a card any card. A/B Switch Cards are available for RS-232 video fiber optic and CAT5e/CAT6 connections. The card featured here is the DB25/RS-232. Use the system for both new and legacy applications. You can add cards for fast CAT6 10-GbE networking while keeping connections for older RS-232 and 75-ohm video connections. Secure and fallback switching. For fail-safe operation all the cards (except those noted) use proprietary latching or micro-mirror relay switching technology- which means data can continue to pass through even if the power has been cut off. Because the cards perform Layer 1 switching the system operates independently of data rates protocols formats or signal levels. The non-latching fiber cards fall back to a Port C (chassis) to Port A connection when the power fails. When power is restored the non-latching switch card reconnects Port C to the originally selected port (A or B). These types of cards are typical when you want a fallback or failover connection during power outages. Each chassis also has a keyed switch so you can enable/disable manual switching from the front-panel toggle switches. Ordering Instructions First order the chassis.
