Connecting Si-Tex Sp-70 Autopilot to E97

[Chuck - Raymarine - Moderator]

Welcome to the Raymarine Forum efontana,

The e97 MFD's Power/NMEA 0183/Video Input Cable features two sets of NMEA 0183 input leads and one pair of NMEA 0183 output leads (yellow (NMEA 0183 OUT1+) & brown (NMEA 0183 OUT1-)). Should the autopilot support 4800 BAUD NMEA 0183 v2.1 or higher communications protocol, then latter set of leads may be interfaced to the corresponding NMEA 0183 input terminals of autopilot (see page 39 of the Si-Tex Sp-70 autopilot's installation guide). Should the MFD's NMEA 0183 leads need to be extended, then it is recommended that commonly available marine grade twisted pair signal cable be used for this purpose. Should the MFD Chart application be commanded to Go To Cursor / Waypoint or to Follow Route, then this action will trigger the MFD to transmit NMEA 0183 navigational sentences via its aforementioned NMEA 0183 output leads. Should the autopilot support tracking based upon receiving such data, then the autopilot may be commanded to into Track mode to cause the autopilot to stee to the waypoint or position indicated by the Chart application's cursor position.
