Raymarine RCR-1, Installation Instructions Manual

Suppression ferrites
• Raymarine cables may be pre-fitted or supplied with suppression ferrites. These are important for
correct EMC performance. If ferrites are supplied separately to the cables (i.e. not pre-fitted), you
must fit the supplied ferrites, using the supplied instructions.
• If a ferrite has to be removed for any purpose (e.g. installation or maintenance), it must be replaced
in the original position before the product is used.
• Use only ferrites of the correct type, supplied by Raymarine or its authorized dealers.
• Where an installation requires multiple ferrites to be added to a cable, additional cable clips should
be used to prevent stress on the connectors due to the extra weight of the cable.
Fitting suppression ferrites
Electromagnetic interference (EMI) from other devices can cause data corruption when reading and
writing to external storage via the card reader. The supplied suppression ferrite should be fitted
to the card reader’s cable to help prevent this.
1. At least one suppression ferrite is required for all installations. The suppression ferrite should be
fitted 6 mm (0.24 in) from the end of the connector end of the cable.
2. 3 suppression ferrites are required for installations where the card reader will be used for
cartography. Two suppression ferrites should be fitted 6 mm (0.24 in) apart from each other at
the connector end of the cable, and one ferrite 53 mm (2.09 in) from the card reader end. For
suitable ferrites, refer to your dealer.
Important: Raymarine recommends MFD internal card readers are used for cartography wherever
possible.
