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