Features and Benefits


  • Simple solution for connecting serial devices to a network
  • Secure operation modes for Real COM, TCP Server, TCP Client, Pair Connection, Terminal, and Reverse Terminal
  • Any Baudrate supported with high precision
  • Choice of network medium: 10/100BaseTX or 100BaseFX
  • Automatic RS-485 data direction control with Moxa's patented ADDC®
  • Port buffers for storing serial data when the Ethernet is off-line
  • SD slot for expanding port buffer memory

Overview

The 2-port NPort® 6250 device servers use the SSL and SSH protocols to transmit encrypted serial data over Ethernet. Models are available for connecting to a 10/100BaseTX copper Ethernet or 100BaseTX fiber network. Both single-mode and multi-mode fiber are supported.


No Data Loss if Ethernet Connection Fails

The NPort® 6250 device servers help guarantee reliability byproviding users with secure serial-to-Ethernet data transmission anda customer-oriented hardware design. If the Ethernet connection fails,the NPort® 6250 will queue all serial data in its internal 64 KB port buffer. When the Ethernet connection is re-established, the NPort®6250 will immediately release all data in the buffer in the order that itwas received. Users can increase the port buffer size by installing anSD card.
