1.7 Running SeaTalk & NMEA2000 cables
Cable routing practices
When running cable, always observe the following guidelines:
• If a cable has to be fed through the deck, always use a good quality deck
gland.
• Where cables are fed through holes, always use grommets to prevent chafing.
• Secure long cable runs so they do not present a hazard.
• Wherever possible, route cables away from fluorescent lights, engines and
radio transmitting equipment, as these may cause interference.
Identifying cables
SeaTalk, SeaTalk
2
and NMEA 2000 buses are used in this system. SeaTalk uses a 3
core cable. SeaTalk
2
and NMEA 2000 use a 5core, screened cable. Each cable type
is available in both madeup form with prefitted connectors, and in unterminated
form on a drum.
