BNAB-COB provides a bidirectional 9600bps RS-232 interface with high ESD immunity. The data connector pinout is suitable for direct connection to the 9-pin COM port of a PC. The hookup cable (provided) is male/female with all pins wired straight through. Any standard terminal program (e.g. HyperTerminal) provides basic control of BOB-II directly from a PC keyboard.
The BNAB-COB encoder interface provides regulated +5V power (100mA max.) to 5V quadrature incremental type encoders. An LS7084 encoder interface IC translates the quadrature outputs from the encoder into pulse and direction data suitable for BOB-II-COB modules. A four-pin .025” square post header with .100” pin spacing and friction lock is provided.
RCA or BNC connectors for video input and output are optional at product ordering time. A 4-pin, .1" header footprint is also provided as a third video I/O connector option. Any standard .025” square post header with .100” pin spacing may be installed, including friction-lock types.
The power connector (J6) accepts a standard coaxial DC power plug. Center pin is V+12, sleeve is ground. Power consumption is less than 100mA, not including encoder power. Decade Engineering suggests a power supply with substantially higher current rating, to prevent voltage sag at turn-on time which could result in a poor reset of the microcontroller in BOB-II.
Product specifications are subject to change without notice. Contact Decade Engineering to confirm current status if any specification is critical to your application.
