1.3 RabbitNet Peripheral Cards
RabbitNet is an SPI serial protocol that uses a robust RS-422 differential signalling
interface (twisted-pair differential signaling) to run at a fast 1 Megabit per second serial
rate. The Coyote has two RabbitNet ports, each of which can support one peripheral card.
Distances between a master processor unit and peripheral cards can be up to 10 m or 33 ft.
The following low-cost peripheral cards are currently available.
Digital I/O
A/D converter
D/A converter
Relay card
Display/Keypad interface
