Plugging directly onto the Control Module, Ethernet UART boards provide up to three high-speed, software configurable serial ports to allow interaction with third party building automation systems and connection of peripheral serial devices to the Concept 4000 Control Module. The Ethernet UART provides a 10BaseT Ethernet connection between the Concept 4000 Control Module and Insight software in addition to up to three serial ports. This allows communication over LAN, WAN, VPN and the internet. Up to four simultaneous connections can be maintained via the UART board - an operator using Insight can be communicating with a Control Module whilst the Control Module is interfacing with building automation systems, high level lift interfaces, Multipath STUs, printers or GSM units.
