BF430 TCPIP Communication Module

A single loop data converter for RS485 to Ethernet that cuts down on rewiring when installing new access controllers.


The BF430 is a RS232/RS485 to TCPIP converter integrated with robust system and network management features. It is designed for use with industrial equipment and easily accessed controlled via intranet or internet. With integration to real time operating system and complete TCP/IP protocol stack capability, the BF430 provides a highly robust and high performance system that connects easily to any network including the internet. Installation of the BF430 is easy with the use of pluggable connectors.

The BF430 web-based configuration is easy to use and operate, and is totally independent of the operating system platform used.
