ARINC 708 describes the characteristics of an airborne pulse Doppler weather radar system. Display data and system mode/status information are transmitted over the display databus from the Transmitter-Receiver unit (T-R) to the Control/Display Unit (CDU).
The LP708-1 is an intelligent PCI interface card for a variety of ARINC 708 Display Databus applications. It can operate simultaneously as a transmitter and receiver. A powerful DSP core and large on-board memory relieves the host PC of 708 protocol processing.
Included are record and playback software utilities that are adequate for many applications. The record utility monitors the databus and writes the data to a file for future analysis or playback. The playback utility can transmit a recorded or user generated file onto the databus.
Applications that require custom software are easily implemented using the provided example source code and C driver library. Driver features include transmit scheduling, a large monitor with time stamp, and an interrupt log list.
The LP708-1 has jumper selectable terminating resistors and is user selectable between two bus connections. Contact Ballard Technology for information on ISA, cPCI, and USB versions of this board.
