![](/p.gif) | 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 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. - 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 More information: Technical details | Serial ports quantity | 2 | ![](/p.gif) | Management protocols | SNMP V1/V2c/V3 | ![](/p.gif) | Serial interface type | RS-232/422/485 | ![](/p.gif) | Isolation | 1.5 kV | ![](/p.gif) | Surge protection voltage | 0.5 kV | ![](/p.gif) | Ethernet LAN data rates | 10,100 Mbit/s | ![](/p.gif) | Certification | CE, FCC | Ports & interfaces | Ethernet LAN (RJ-45) ports | 1 | Design | Safety | UL (UL60950-1), TÜV (EN60950-1) | Power | Input voltage | 12 - 48 V | Protocols | Supported network protocols | ICMP, IP, TCP, UDP, DHCP, BOOTP, Telnet, DNS, HTTP, SMTP, ARP, PPPoE, DDNS | Other features | Compatible operating systems | Windows 95, 98, ME, NT, 2000, XP, 2003, Vista, XP x64, 2003 x64, Vista x64; SCO Unix, SCO OpenServer, UnixWare 7, UnixWare 2.1, SVR 4.2, QNX 4.25, QNX 6, Solaris 10, FreeBSD, AIX 5.x, HP-UX 11i | Security | Security algorithms | 3DES, 802.1x RADIUS, DES, HTTPS, SSH, SSL/TLS | Indication | Connectivity LEDs | 7 | Weight & dimensions | Weight | 730 g | ![](/p.gif) | Dimensions (WxDxH) | 89 x 111 x 28 mm | Operational conditions | Operating temperature (T-T) | 0 - 55 °C | ![](/p.gif) | Storage temperature (T-T) | -20 - 85 °C | ![](/p.gif) | Operating relative humidity (H-H) | 5 - 95 % |
