The BAScontrol22D is a 22-point unitary controller which supports BACnet client/server operation over BACnet/IP. The controller complies with the B-ASC device profile having a convenient mix of 8 universal inputs, 4 binary inputs, 4 analog outputs, and 6 binary outputs. Unique to the unit are 48 web components which link Sedona wiresheet readable/writeable data to webpages, and 24 virtual points which link Sedona wiresheet readable/writeable data to a BACnet client. The device is fully webpage configurable, and freely programmable using Sedona's function block programming methodology of assembling components onto a wiresheet to create applications. The unit can be programmed using the BAScontrol Toolset. The controller is powered by a 24VAC/VDC source. Rugged design, low profile, and wide temperature operation make it suitable for indoor or outdoor use. The BAScontrol22D utilizes a 32-bit ARM7 processor with 512 kB of flash memory, plus a 16 Mbit serial flash file system for storing configuration data and an application program. By operating at the BACnet/IP level, the BAScontrol22D can share the same Ethernet network with supervisory controllers, operator workstations, or IP routers. Dual 10/100 Mbps auto-negotiating Ethernet ports support protocols such as BACnet/IP, Sedona Sox, HTTP, and FTP. The unit can be configured for a fixed IP address or can operate as a DHCP client receiving its IP address from a DHCP server. An LED indicator identifies a link condition while flashing during data transfer.
