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