Ce Compliance - Digi Rabbit Smartcat BL2100 Series User Manual

1.5 CE Compliance

Equipment is generally divided into two classes.
CLASS A
Digital equipment meant for light industrial use
Less restrictive emissions requirement:
less than 40 dB µV/m at 10 m
(40 dB relative to 1 µV/m) or 300 µV/m
These limits apply over the range of 30–230 MHz. The limits are 7 dB higher for frequencies
above 230 MHz. Although the test range goes to 1 GHz, the emissions from Rabbit-based
systems at frequencies above 300 MHz are generally well below background noise levels.
The BL2100 single-board computer has been tested and was found to
be in conformity with the following applicable immunity and emission
standards. The BL2110, BL2120, and BL2130 single-board computers
are also CE qualified as they are sub-versions of the BL2100 single-
board computer. Boards that are CE-compliant have the CE mark.
Immunity
The BL2100 series of single-board computers meets the following EN55024/1998 immu-
nity standards.
• EN61000-4-3 (Radiated Immunity)
• EN61000-4-4 (EFT)
• EN61000-4-6 (Conducted Immunity)
Additional shielding or filtering may be required for a heavy industrial environment.
Emissions
The BL2100 series of single-board computers meets the following emission standards with
the Rabbit 2000 spectrum spreader turned on and set to the normal mode. The spectrum
spreader is only available with Rev. C or higher of the Rabbit 2000 microprocessor. This
microprocessor is used in all BL2100 series boards that carry the CE mark.
• EN55022:1998 Class A
• FCC Part 15 Class A
NOTE: The BL2100 satisfied the Class A limits but not the Class B limits. Such equip-
ment need not be restricted in its sale, but the following warning must be included in
the instructions for its use.
This is a Class A product. In a domestic environment this product may cause radio
interference, in which case the user may be required to take adequate measures.
Additional shielding or filtering may be needed to meet Class B emissions standards.
6
Digital equipment meant for home use
More restrictive emissions requirement:
30 dB µV/m at 10 m or 100 µV/m
