Secure Ethernet data mode for TCP Server, TCP Client, Pair Connection, Real COM Driver, and RFC2217
Any Baudrate mode for more precise baudrates
Uses SD card to increase port buffering size
 
 
Introduction
 

NPort 6250's serial port can be configured for RS-232, RS-422, or RS-485 (both 2-wire and 4-wire RS-485 are supported). Either copper or fiber (single-mode or multimode) can be used for the Ethernet port.

Prevent Data Loss when the Ethernet Fails
NPort 6250 device servers are reliable serial-to-Ethernet products that provide users with secure data transmission and a customer-oriented hardware design. When the Ethernet connection fails, NPort 6250 will queue all of the serial data in its internal 64 KB port buffer. When the Ethernet is reconnected, NPort 6250 will immediately send all of the data stored in the buffer in the order that it was received. Users can expand the storage size by using NPort 6250's SD card expansion feature.
