2.40 NT888G MK2 Second Station Control Units.
All NT888G MK2 Autopilot system Control Units are identical and may be used in
Master/Slave configurations as required up to a maximum of 3 Control Units per
system.
NB.
Where more than one Control Unit is involved it is important to note that each
must have its own dedicated address (No.1, No.2 or No.3).
(At power up, all Control Units display a splash screen – Section 2.14 – showing
current address status details etc. If two addresses are the same, this will produce a
communication conflict thus address changes will be required. (See Section 3.0 of the
Installation and Technical Manual).
When two or three Control Units are correctly installed with different address
numbers, address No. 1 will normally assume Master status. If it is required to change
Master status to No.2 or No.3, this can be achieved by simultaneous operation of the
subject
ON
and
REMOTE
keys as follows:-
a) Check that the current Master unit (normally address No.1) is switched ON
with its REMOTE key also ON to enable other stations entry to the Autopilot
system.
NB.
If there is doubt which Control Unit is the current “Master”, note that initial
power up will display either Master or 2
nd
station on the splash screen. (See
Section 2.14).
b) Set the new required Master station to
STANDBY
.
c) Use the
ON
and
REMOTE
keys simultaneously for a period of 5 seconds to
transfer Master status to the subject Control Unit confirmed by a double
bleep.
d) Check transfer by powering down and powering up again when the splash
screen should confirm “Master Station” on the subject Control Unit.
(Similarly, the previous Master station should now show “2
nd
Station” on its
splash screen when powered down and up again).
