3-Axis Synchro/Resolver to Serial Converter Card
The BBG-1108B is an ISAbus compatible card which supports standard 3-Axis Gyro input and converts it into four serial outputs. (Roll, Pitch, Heading, and Combined). The BBG-1108b standard message format uses the NMEA 0183 message structures and supports RS-232, RS-422, RS-423, RS-485, and MIL-STD-188C protocols.
The BBG-1108b is a “SMART” interface due to the onboard processor which communicates with the PC bus through shared memory, thus, requiring minimum PC processor time. Synchro/resolver inputs are processed by the onboard processor and stored in shared memory. This information is then read by the PC processor under interrupt control or polled operation. Software drivers included with the BBG-1108b provide easy integration, thus, shortening product development cycle and time to market. DC power is supplied by the PCbus requiring no external power supplies.
In situations not requiring a PC interface, the BBG-1108b operates in a “STAND-ALONE” mode. With the addition of an external +5 volt power supply, the onboard processor converts the synchro/resolver inputs into serial data formats without the requirement of a PC bus. Upon applying power, the BBG-1108b reads the configuration switch, and fully configures and operates with no operator intervention required.
Synchro/resolver signals, reference inputs, and serial outputs are available on a 50 pin male (DB50P) connector.
