Why add a fourth helm?
- Get a better view while maneuvering. Add an operating position where you can see the dock, stern or working area.
- Use another helm without duplicating the engine hardware. The added control head communicates with the compatible base system.
- Plan the station connection. Match the station-specific T-harness and bus-harness route to the system wiring diagram.
Included in the KE512A-4 station kit
- 1 × NM2012-00 — Single-Engine KE-XG Control Head - Chrome - Composite Lever
- 1 × NM0647-19 — KE-XG T-Harness (R/C-4)
- 1 × control-head buzzer: NJ0251-00 for 12 V or NJ0515-00 for 24 V
Required separately and installation planning
- NM0649 bus harness — select the section length for the added station. Confirm each route length against the applicable wiring diagram. Bus, power and engine-interface harnesses have different roles.
- KE512 — a compatible KE5XG base installation must already be present or supplied separately. The station kit does not include another control unit.
- Use a laptop, NM1476-01 settings-tool harness and USB-KE-Adapter Harness for programming, following the KE-XG settings manual.
- The existing catalog lists an 80m limit for the total CANbus-harness run. Confirm the complete route and the permitted total length for the installed system with Seatech before ordering.
Request complete system pricing to include the required harnesses, cables and other installation parts.
