描述 Description

L-com's DB9 switch box products are physical layer hardware solutions which support a variety of switching, or access and control applications all in a compact desktop enclosure. These DB9 serial switch boxes feature a unique relay technology that supports the switching mechanism. Non-latching or latching relay configurations are available. The non-latching units provide automatic fail-over to the default Port A to C connection state when power fails or is removed. Latching versions provide the benefit of maintaining the flow of data between the connected devices even when power is removed. Note: The Ethernet models may be controlled via telnet, web browser or SNMP. Ships with a universal 12V DC power supply with four different style country plugs. Custom configurations are available.
