6 Rabbit 2000 Development Kit
Safety
• For personal safety, all inputs and outputs to and from the BL1800 series of single-
board computers must not be connected to voltages exceeding SELV levels (42.4 V AC
peak, or 60 V DC). Damage to the Rabbit 2000 microprocessor may result if voltages
outside the design range of 0 V to 5.5 V DC are applied directly to any of its digital
inputs.
• The lithium backup battery circuit on the BL1800 single-board computer has been
designed to protect the battery from hazardous conditions such as reverse charging and
excessive current flows. Do not disable the safety features of the design.
1.4.3 Interfacing the BL1800 to Other Devices
Since the BL1800 series of single-board computers is designed to be connected to other
devices, good EMC practices should be followed to ensure compliance. CE compliance is
ultimately the responsibility of the integrator. Additional information, tips, and technical
assistance are available from your authorized Rabbit Semiconductor distributor, and are
also available on the Z-World Web site at www.zworld.com.
