ARINC 429 Channels
ARINC 429 receive channels speed may be set by the user or defined through automatic speed detection and independent label and SDI filtering. Transmit channels may be independently set for standard low or high speed bit rate (12.5 or 100 Kbps). Each transmit channel automatically maintains accurate label repetition rates and are capable of driving a full 20 standard ARINC 429 receiver loads. To support data transfer protocols, aperiodic words may be transmitted without altering the timing of periodic words. All channels can be monitored independently or by using a channel/label filter. Messages can be captured by a sequential monitor buffer for the entire interface. The BTIDriver API provides for automatic scheduling of labels based on transmission rates, making it straight-forward to implement transmission schedules from an ICD or migrate from third party products.
ARINC 717 Channels
The PM429-2 offers two transmit and two receive ARINC 717 channels. Each ARINC 717 channel is independently configurable through software for Harvard biphase or bipolar return-to-zero operation. Sub-frame data structures are used to transmit and receive from the ARINC 717 databus. In addition, super-frames can be enabled with configurable counter location and number of frames per super-frame.
