BBG-SSBA Serial to Synchro/Resolver Booster Amplifiers

The BBG-SSBA is a 6U VME FORMAT pc card which inputs a serial data message containing a speed or angular position. This information is processed by the onboard microcontroller and output in a synchro or resolver format. The BBG-SSBA is available in 25VA and 125VA output power configurations. An onboard microcontroller configures the card from power up or reset and provides all signals and controls to read the serial information and output the synchro/resolver information. Serial data formats, power outputs, synchro and resolver voltages and frequencies are factory configurable to user requirements.

Synchro information is passed over the serial data bus in a binary angle measurement format (BAM) as shown in Table 2 (on the data sheet). The BBG-SSBA accepts serial data in RS-232, RS-422, RS-423, RS-485, or MIL-STD-188C protocols. Serial baud rates are switch selectable at: 1200, 2400, 4800, 9600, and 19,200 bits per second. Default data output is 9600, 8 bits, no parity, and one stop bit (9600, 8, N, 1). Table 3 (on the data sheet) defines the switch position for the available baud rates. Custom serial data formats and frequencies are available upon request.
