Bulkhead Mount, or Rack Mount, Serial to Synchro/Resolver Interface

Introduction	Serial Input, Two-Speed Synchro/Resolver and Serial Outputs NMEA Type 12/13 or 19 inch Rack Mount Enclosure NMEA-0183 Compatible Outputs RS-232, RS-422, RS-423, RS-485, MIL-STD-188C Protocols AC Input Filtered and Circuit Breaker Protected The BBG-550 is a bulkhead mount NMEA 12/13, or 19 inch rack mount enclosure which converts angular information from a serial data message into three outputs: a two speed synchro or resolver output and a NMEA-0183 serial data format.
	The serial data input/output uses the NMEA 0183 message structures and supports RS-232, RS-422, RS-423, RS-485, and MIL-STD-188C protocols. Custom message formats are available upon request.
	Power input, serial input, reference inputs, synchro/resolver outputs, and serial outputs are available on standard militarized connectors. Synchro outputs are virtually indestructable incorporating current limiting, short circuit protection, overvoltage transient protection, and thermal cutoff. AC input power is filtered and circuit breaker protected.
	The BBG-550D includes a backlighted Liquid Crystal Display (LCD) which provides a visual indication of the synchro angle outputs.

BBG-550/550D Overview	The BBG-550 is a bulkhead mount NMEA 12/13, or 19 inch rack mount enclosure which converts angular information from a serial data message into three outputs: a two speed synchro or resolver output and a NMEA-0183 serial data format.
	The two speed synchro or resolver outputs are factory configurable to user defined voltages and frequencies. Outputs are transformer isolated and fully protected against overloads, transients from load kickbacks, short circuits and overheating.
	The serial data output os transmitted over RS232 and RS422 interfaces usinf NMEA-0183 message structure. This output is transmitted over both RS-232 and RS-422 interfaces. Input and output baud rates are switch selectable on the Digital to Synchro Processor housed internal to the BBG-550. 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).

NMEA 0183
Format

The BBG-550 can be factory programmed for any NMEA 0183 data format or any custom data format. Current data format for two-speed synchro operation is as follows:

$PTBBG,XXX.XX,A*CSCRLF

$       Start of message ascii character 24 Hex
PT      Proprietary message
BBG     BBG Incorporated
XXX.XX  Channel 1 synchro/resolver angle (ex: 045.01) 
A       Validity (A = valid, V = Invalid)
*       ascii character 2A Hex
CS      Checksum (8 bit XOR of characters between $ and *)
CR      Carriage return
LF      Line feed

Optional Synchro/
Resolver Outputs

The BBG-550 can be factory configured for 90Vrms, 11.8Vrms, and/or 6.8Vrms synchro or resolver outputs at 60Hz or 400Hz. Custom voltages and frequencies are available upon request. Please specify desired voltage and frequency when ordering.
