Introduction

1-9
1.8 Dual Station
See Fig. 1-7
The AP9 MK3 Control Unit can also be used as a remote station,
communicating with the main station by serial lines.
The dual station system is designed to enable individual connections
of NFU levers, F200-40 remote controls and mode selectors. This
makes it possible to select mode and change parameters from the two
stations individually. FU levers can only be connected to the main
Control Unit via D9X.
Note !
Change of parameters except the selection of compass on one unit, will
change the same parameters on the other unit.
Parameter 2 option (Thruster function) can be selected individually
on the two units, but adjustment of parameters on one unit will
automatically change the same parameters on the other unit.
When a F200-40 Remote Control is connected, a mode selector must
have an "OFF" position to allow proper function of the F200-40.
SERIAL LINES
The AP9 MK3 has several serial line connections.
As shown in Fig. 1-6, two input lines are in parallel, the "COMM.
LINE" and the "SERIAL HDG. DATA". This excludes the interface to
serial heading data when a dual station is used.
