MOXA NPort 6250-S-SC INTRODUCTION
The NPort® 6000 device servers use the SSL and SSH protocols to transmit encrypted serial data over Ethernet. The NPort® 6000’s 3-in-1 serial port supports RS-232, RS-422, and RS-485, with the interface selected from an easy-to-access configuration menu. The NPort® 6000 2-port device servers are available for connecting to a 10/100BaseT(X) copper Ethernet or 100BaseT(X) fiber network. Both single-mode and multi-mode fiber are supported.
Secure Data Transmission
For many applications, guaranteeing secure data transmission is an important concern when connecting serial devices to a network. To answer this concern, the NPort® 6000 supports the SSL and SSH protocols, which encrypt data before sending it over the network. With the NPort® 6000, users can rest assured that serial data is transmitted securely over both private and public networks.
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 of the data in the buffer in the order that it was received. Users can increase the port buffer size by installing an SD card.
