Appendix D: Interfacing to SI-TEX Autopilot and Compass Display

Commander P2 or Admiral P3 and Navigation 3D

Figure 1 shows the typical connections used with a SI-TEX Commander P2 Autopilot System (an Admiral
P3 would be wired identically), a Navigator G2 GPS Compass Display System, and a generic Chartplotter or
other type of Navigation System.

Note: this wiring information assumes that the 3D is in its factory-default
configuration: Autopilot data on Port A. Port C defaults to NMEA 2000.

Use SI-TEX toolkit software to convert to 0183 if required. (CD included)

Table 3 - Commander P2 Connection Detail


In addition to the above wiring, the Commander P2 must be configured to look for both heading and speed
data from its NAV1 input port, and for Navigation data from NAV2; for details, see the respective Source
selection descriptions for the Standby, Auto & Nav menus, in the P2 Installation & Operation manual.

Other SI-TEX Autopilot Systems

All other SI-TEX autopilots require the use of an optional Sine-Cosine Interface Box (PN 21010004), with
matching interface cable (PN 31110023 or 31110051), to use them with a Vector 3D.

See the instructions included with the Sine-Cosine Box for wiring and setup information. Note that the 3D's
Port C Tx and the signal ground wires are the ones to be connected to the Convertor.
