To minimize downtime, this intuitive dual Ethernet serial over IP solution maintains connection to your critical equipment by automatically switching to its secondary LAN port within 10 milliseconds of a network failure or disruption. Ideal for industrial environments, the serial to Ethernet device server accepts wide-range 12-48V DC power input via a terminal block, or through a Po E RJ45 port. Redundant power inputs keep the device server functional in the event of power surges or failures, and when used with a Po E-capable switch or injector, the serial device server can be conveniently installed in locations where terminal block power is unavailable. This device server supports baud rates up to 460. 8Kbps which provides a smooth, high-speed connection to your serial devices. The de
