A printer can also be connected for any mode, except when using
NMEA output. If you connect a printer and select the "GPS" or "EXT.
NMEA" connection option, you will need to turn off your printer before
turning off the RayChart, or NMEA data will be repeated to the printer.
If you need to use both SeaTalk and NMEA equipment in your system,
you can do so by connecting the NMEA equipment via a unit that
repeats NMEA data in SeaTalk format, such as the RayData.
If your SeaTalk system does not include a RayData , you should
connect your NMEA equipment via a Raytheon Electronics
NMEA/RS-232 Interface Box (part number Z290), which has full
SeaTalk/NMEA conversion capabilities.

Cabling

Plan your cable runs before you start the installation. Consider the
following points:
• All cables should be adequately cleated and protected from physical
damage and exposure to heat
• Acute bends must be avoided
• Where a cable passes through an exposed bulkhead or deckhead, a
watertight gland or "swan neck" tube should be provided
