Changing The software is stored in the EPROM, IC 11. To change the
Software eprom, first disconnect any power to the Distribution Box.
Eproms Remove the cover and internal RFI shield. IC11 is located in
the centre of the PCB, replace the existing eprom with the
new one, being certain that pin 1 is in the correct position
(away from the motor connection block) and that no pins
are bent or miss their socket. Refit the RFI shield and cover.
Restore the power supplies and turn the autopilot on. The
display may show system fault ‘
F002
’ to start with. If it
does, switch the autopilot Off then On again and this
should clear the condition. If it does not then almost
certainly the eprom has not been fitted correctly.
Switches There is an eight way DIL switch on the PCB which is used
to change the way the Distribution Box functions. It is
situated in the top right quadrant of the PCB with switch
one (SW1) being nearest the centre of the board. The ON
position is defined as when the switch is pushed up
towards the FET’s.
The functions of the switches are as follows:
SW5 Switch to the ON position when using a Rudder Feedback
Unit that has no integral limit switches, i.e. 930 807.
Switch to the OFF position when using a Rudder Feedback
Unit that has integral limit switches, i.e. 930 801.
SW6 Switch to the ON position when using a Rudder Feedback
Unit that has no integral limit switches, i.e. 930 807.
Switch to the OFF position when using a Rudder Feedback
Unit that has integral limit switches, i.e. 930 801.
SW7 Switch to the ON position when a Navigator with a single
wire output is connected to the NAV1 port.
Switch to the OFF position when a Navigator with a two
wire output is connected to the NAV1 port.
