BBG-7XXX-PCA
The BBG-7XXX-PCA is a standalone PCB module with a Gigabit Ethernet Input & Synchro Output. It also has an embedded NMEA processor, up to four synchro receive channels, and two synchro transmitters. The NMEA processor can be configured in the field to generate arbitrary sentences in real time over serial and ethernet.
The BBG-7XXX-PCA is a customizable circuit card with a gigabit ethernet input & synchro output, NMEA processor & four synchro receive channels. It connects synchros and NMEA interfaces with flexible connectivity. Users can connect to a USB serial console to reconfigure application behavior in the field, as well as debug and test the system.
The PCA comes factory-configured to support up to four synchro inputs and two synchro outputs. When ordering, specify the configuration and reference frequency (60 Hz or 400 Hz). Users can scale the synchro values to meet any synchro scaling requirements.
The stock configuration includes two isolated serial ports, user-configurable as RS-232 or RS-422. Each port can independently operate at any baud rate with any valid NMEA message. A Gigabit Ethernet interface is available for network connectivity when needed.
The NMEA engine (application firmware) supports generating and transmitting arbitrary messages on all interfaces, populating messages with any combination of supported variables such as synchro angles or network time.
The PCA operates with 12VDC power through either J1 or J2 in standard configuration. Users can also power the PCA through their computer’s USB port for debugging, checking servo motor positions, writing servo output values manually, and monitoring UART data.
The BBG-7XXX PCB receives, interprets, and transmits data to the digital-to-synchro converter modules on the underside of the PCA. The functionality is determined by jumpers and the configuration switch (S1) at power-on or reset. The PCA includes one Ethernet input channel and two synchro output channels.
A 3-port onboard Gigabit Ethernet switch offers high-bandwidth packet filtering, routing, and interfacing. Upon power-on or reset, an onboard microcontroller reads the configuration switch, configures the network interface, and manages all necessary signals and control to read, process, and output data.
The digital-to-synchro converter modules use the “digital” angle to drive the attached equipment. A USB serial console is available for configuration and debugging.
