RabbitLink card. If you are already connected to a network it may be necessary for the network
administrator to assign an IP address to be used by the RabbitLink.
1.4.3 Passphrase Protection
Every time Dynamic C initiates a new RabbitLink session, the RabbitLink requests a passphrase
from the user to ensure the security of the programs and data on the remote boards. This pass-
phrase is stored by Dynamic C during that session so it only needs to be entered the first time
Dynamic C contacts the RabbitLink gateway. For security reasons, Dynamic C does not store the
passphrase on the hard disk of the PC.
1.5 RabbitLink CE Compliance
This section describes the immunity and emissions standards met by the RabbitLink. Design
guidelines are given to help developers incorporate the RabbitLink into an application while stay-
ing CE compliant.
Equipment is generally divided into two classes.
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 RabbitLink has been tested and was found to be in conformity with the following applicable
immunity and emission standards. Boards that are CE-compliant have the CE mark.
Immunity
The RabbitLink meets the following EN55024/1998 immunity 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.
CLASS A CLASS B
Digital equipment meant for light industrial use Digital equipment meant for home 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
More restrictive emissions requirement:
30 dB µV/m at 10 m or 100 µV/m
