The “System select” (Sys. Sel.) input signal of the J50 can be used 
to alternate between the boat’s own steering and the autopilot 
system from an external system selector (refer to IMO resolution 
MSC. 64 sec. 4). A ground on TB14 Sys. Sel. will force the 
system into Disengage mode. The autopilot will be disconnected 
from the vessel’s steering system and show “Disengaged” on the 
display (on the FU50, no mode indicators will be lit). When the 
“Sys. Sel.” input line is re-opened, the autopilot will go to AUTO 
mode. For wheelmark installation (Master operation = Yes, ref. 
page 121) the master control unit will be active. 

For non-wheelmark installations the autopilot will continue on the 
present heading, but no course change can be made before a 
control unit is activated again by pressing the AUTO button. 

The Port/stbd lines of the J50 Remote terminal can be used to 
alternate between automatic and electric hand-steering from the 
autopilot. This may be used for armrest operation, etc. When in 
AUTO mode or NAV mode, a simultaneous pulse from the Port 
and Stbd terminals to the ground terminal on the remote 
connection will revert the autopilot to STANDBY mode. The 
next pulse will bring the autopilot to AUTO mode.
