EXPANDABLE CONTROL
BOARDS
RABBITNET SERIES
™
A point-to-point synchronous protocol that connects
additional I/O and analog cards to a master device
The RabbitNet signals are differential RS-422, which are
series-terminated at the source. Peripheral cards and master
controllers connect using a standard CAT 5/6 Ethernet cable or
a crossover cable if using an OP7200 as a slave display.
There are several RabbitNet card options which include:
– RN1100 - Digital I/O
– RN1200 - A/D
– RN1300 - D/A
– RN1400 - Relay expansion
– RN1600 - Keypad display interface
The RabbitNet system typically consists of a master single-
board computer and one or two peripheral cards. Several
Rabbit SBCs such as the BL4S200 or BL2600 act as the master
controller for fast data processing and provide the power on
board needed for the peripheral cards.
Distances between a master unit and peripheral cards
can be up to 10 m or 33 ft with speeds up to 1 Megabit per
second. Cards can be mounted in 100 mm DIN rail trays and
optionally there is a RN1000 hub to connect up to 8 devices.
