Digital to Synchro/Resolver
"Smart" Converter Card
The BBG-1014a is a PCbus
compatible card which interfaces to any slot of an
IBM PC or clone. This board supports standard 16 bit
BCD input (speed log) and converts it into a synchro/resolver
format and a serial data format.
The synchro format output is a
standard 5 wire (S1,S2,S3,RL, and RH) at 90V LL or
11.8V LL. Resolver output is a standard 6 wire (Sin,
Sin Return, Cos, Cos Return, RH, and RL) at 6.8Vrms.
Standard reference inputs of 60 Hz and 400 Hz are
supported with custom voltages and frequencies
available upon request.
The serial data output uses the
NMEA 0183 message structures and supports RS-232,
RS-422, RS-423, RS-485, and MIL-STD-188C protocols.
The BBG-1014a is a "SMART" interface
due to the onboard processor which communicates with
the PCbus through shared memory, thus, requiring
minimum PC processor time. DC power is supplied by
the PCbus and Synchro/Resolver outputs are powered
by the ac reference voltage. Therefore, no external
power supplies are required.
In situations not requiring a PC
interface, the BBG-1014a operates in a "STAND-ALONE"
mode. With the addition of an external +5 volt power
supply, the onboard processor converts the BCD
inputs into synchro/resolver and serial data formats
without the requirement of a PCbus.
Reference inputs, synchro/resolver
outputs, and serial outputs are available on a 50
pin male (DB50P) connector.

||The DS-1014a is a full-size IBM PC card which inputs a 14-bit BCD value
representing a speed or angular position. This information is processed
by the onboard microcontroller and output in three different data formats.
A NMEA-0183 serial data format updated at a rate of once per second is
transmitted over both RS-232 and RS-422 interfaces. A factory configurable
synchro or resolver output representing speed or angular position is output
continuously at a user defined voltage and frequency. A binary angle measurement
format (BAM) number as shown in Table 2 (on the data sheet), is passed through dual port memory
to the PCbus on demand from the host computer.
The DS-1014a can, also, be used without a computer in a stand alone
mode. An onboard microcontroller configures the card from power up or reset
and provides all signals and control to read the BCD information and output
the synchro/resolver information and the NMEA 0183 data message.
When used in a computer configuration, switches provide for bus address
selection and interrupts IRQ2 thru IRQ7 are jumper selectable. Baud rates
are switch selectable and can be programmed via the PC bus. Selectable
baud rates include: 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.
