Moxa Terminal Servers - NPort 6250 Series 2-port RS-232/422/485 secure terminal servers

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
Non-standard baudrates supported with high precision
Choice of network medium: 10/100BaseTX or 100BaseFX
Enhanced remote configuration with HTTPS and SSH
Port buffers for storing serial data when the Ethernet is off-line

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.

Zero Data Loss if Ethernet Connection Fails

The NPort® 6250 device servers help guarantee reliability by providing users with secure serial-to-Ethernet data transmission and a 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 it was received. Users can increase the port buffer size by installing an SD card.
