4 port, Serial Server |
 BF-440 serial device servers are designed to make your industrial serial devices Internet ready instantly. The compact size of BF-440 device servers makes them the ideal choice for connecting your RS-232 or RS-422/485 serial devices such as PLCs, meters, and sensors to an IP-based Ethernet LAN, making it possible for your software to access serial devices anywhere over a local LAN or the Internet.
BF-440 serial device servers ensure the compatibility of network software that uses a standard network API (Winsock or BSD Sockets) by providing TCP Server Mode, TCP Client Mode, and UDP Mode. And using Chiyu's virtual COM drivers, software that works with COM ports can be set up to work over a TCP/IP network in no time. This excellent feature preserves your software investment and lets you enjoy the benefits of networking your serial devices instantly.
BF-440 serial device servers support automatic IP configuration protocols (DHCP, BOOTP) and manual configuration via Chiyu's web browser console. Both methods ensure quick and effective installation. BF-440 support special design for PPPoE + DDNS that could let your device to connect to Internet without static IP address. |
