The RabbitNet RN1100 Digital I/O card is the first in a series of peripheral I/O cards designed for use with Rabbit controller products with RabbitNet expansion ports, such as the BL2500 Coyote and OP7200 eDisplay. The cards are DIN rail mountable and have friction-lock connectors for simplified OEM manufacturability.

RabbitNet

The RabbitNet expansion ports enable a modular and expandable embedded control system whose configuration of I/O cards can be tailored to a large variety of demanding real-time control, display, and data-acquisition applications. A typical RabbitNet system consists of a master single-board computer and one or more peripheral I/O cards. A high-performance Rabbit microprocessor on the master provides fast data processing, and the BL2500 master also provides the DCIN and +5 V power for the peripheral boards.

Programming RabbitNet Cards

The Digital I/O Board is a slave; the master to which RabbitNet boards are connected is programmed using version 8.01 or later of Rabbit's Dynamic C.

Dynamic C includes comprehensive debugging support includes break points, watch expressions and many other extensive features oriented toward real-time embedded systems programming. An extensive library of drivers and sample programs is provided, including a royalty-free TCP/IP stack for network and Internet communications. Full source code is provided for most library routines. Dynamic C is sold separately.

Connectivity Tools

Rabbit offers a connectivity kit for wiring assemblies that interface with the friction-lock connectors on the digital I/O board.
