 DE-211/311
1-port RS-232/422/485 serial device servers
3-in-1 serial port: RS-232, RS-422, or RS-485
 
Versatile operation modes including TCP Server, TCP Client, 
 
UDP, Ethernet Modem, and Pair Connection 
Real COM/TTY drivers for Windows and Linux 
 
10M and 100M Ethernet speeds detected automatically
 
2-wire RS-485 with patented Automatic Data Direction Control 
 
(ADDC®) 
Built-in 15 KV ESD protection for all serial signals
 
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.
