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.
