Introduction

Moxa NPort® 6450 is a terminal server that uses the SSL and SSH protocols to transmit encrypted serial data over Ethernet. Up to 4 serial devices of any type can be connected to the NPort® 6450, using the same IP address. The Ethernet port can be configured for a normal or secure TCP/IP connection. The NPort® 6450 secure device servers are the right choice for applications that use large numbers of serial devices packed into a small space. Security breaches are intolerable and the NPort® 6450 Series ensures data transmission integrity with support for DES, 3DES, and AES encryption algorithms. Serial devices of any type can be connected to the NPort® 6450, and each serial port on the NPort® 6450 can be configured independently for RS-232, RS-422, or RS-485 transmission.

No Data Loss If Ethernet Connection Fails

Moxa NPort® 6450 is a reliable device server that provides users with secure serial-to-Ethernet data transmission and a customer-oriented hardware design. If the Ethernet connection fails, the NPort® 6450 will queue all serial data in its internal 64 KB port buffer. When the Ethernet connection is re-established, NPort® 6450 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.

LCD Panel Makes Configuration Easy

NPort® 6450 features a built-in LCD panel for configuration. The panel displays the server name, serial number, and IP address, and any of the device server’s configuration parameters, such as IP address, netmask, and gateway address, can be updated easily and quickly.

Note: The LCD panel is only available with standard-temperature models.

Adjustable Resistor Values for RS-485 Communication

NPort® 6450 provides adjustable termination, pull high, and pull low resistors for RS-485 communication. In some critical environments, termination resistors may be needed to prevent the reflection of serial signals, and the pull high and pull low resistors may need adjusting to maintain the integrity of the electrical signal. Since no set of resistor values works for every environment, NPort® 6450 allows manual adjustment of the resistor values for each serial port using built-in DIP switches.
