SI-TEX SP-70 & SP-80 Autopilot Systems
Introduction
There is an alternate new cable type for the SP-80 Control Unit cable and the Fluxgate
Compass cable. This cable has a different colour code than the original cable type,
although it is otherwise identical.
As well, there is now an alternate SP-70 Control Unit Receptacle cable, with a different
colour code than the original cable.
Starting with systems manufactured in the Summer of 2009, either the original or the
alternate type of cable may be used, for any of the items above.
As a result, the wiring information for the SP-70 Control Unit Receptacle cable, the
SP-80 Control Unit and the Fluxgate Compass, in the Installation & Operation manual
(PN 20910049, version 1.2, April 2004) must be revised.
Please use the next two pages of this Addendum, instead of pages 37 & 38 in the
current manual.
