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 units can be programmed using our free licence Sedona programming tool Sedona Application Editor (SAE). 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. Depressing a hidden IP Reset switch returns the controller to default IP address settings.
As a BACnet server device, the BAScontrol22D will respond to a BACnet client request by default over the IP port. This means that the BAScontrol22D can function as remote I/O to BACnet clients over IP without needing a Sedona program. Through webpage configuration of connected BACnet servers, the BAScontrol22D can function as a BACnet client to these devices over IP. This requires the use of Sedona network variables (NetVs) found in the NetV kit. This capability allows the BAScontrol22D to initiate messages over IP to other BACnet devices without the need for BACnet headend intervention.
