The NPort® DE-211 and DE-311 are 1-port serial device servers that
support RS-232, RS-422, 4-wire RS-485, and 2-wire RS-485. The
DE-211 supports 10 Mbps Ethernet connections and has a DB25
female connector for the serial port. The DE-311 supports 10/100
Mbps Ethernet connections and has a DB9 female connector for the
serial port.
Both device servers are ideal for applications that involve information
display boards, PLCs, flow meters, gas meters, CNC machines, and
biometric identification card readers.
