Up to 4 serial devices of any type can be connected to the NPort® 6450, with The 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 all four devices using the same IP address. The Ethernet port can be configured for a normal or secure TCP/IP connection. connection is re-established, the 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 a SD card. 4-port RS-232/422/485 secure terminal servers Specifications Overview No Data Loss if Ethernet Connection Fails NPort 6450 › ›LCD panel for easy IP address configuration (standard temp. models) › ›Secure operation modes for Real COM, TCP Server, TCP Client, Pair Connection, Terminal, and Reverse Terminal › ›Nonstandard baudrates supported with high precision › ›Port buffers for storing serial data when the Ethernet is offline › ›Supports IPv6 › ›Ethernet redundancy (STP/RSTP/Turbo Ring) with network module › ›Generic serial commands supported in Command-by-Command mode Ethernet Interface Number of Ports: 1 Speed: 10/100 Mbps, auto MDI/MDIX Connector: 8-pin RJ45 Magnetic Isolation: 1.5 kV built-in Optical Fiber Interface (with network module) 100BaseFX Multi-Mode Single-Mode Fiber Cable Type OM1 50/125 μm G.652 800 MHz*km Typical Distance 4 km 5 km 40 km Wave- length Typical (nm) 1300 1310 TX Range (nm) 1260 to 1360 1280 to 1340 RX Range (nm) 1100 to 1600 1100 to 1600 Optical Power TX Range (dBm) -10 to -20 0 to -5 RX Range (dBm) -3 to -32 -3 to -34 Link Budget (dB) 12 29 Dispersion Penalty (dB) 3 1 Note: When connecting a single-mode fiber transceiver, we recommend using an attenuator to prevent damage caused by excessive optical power. Note: Compute the “typical distance” of a specific fiber transceiver as follows: Link budget (dB) > dispersion penalty (dB) + total link loss (dB).
