2-2 External control devices
2.2 External control devices
Depending on the installation, external devices may be present to
remotely control certain functions of the NAVIKNOT 600 SE:
• The audible alarm at the NAVIKNOT 600 SE may be muted from a
remote device, e.g. a central alarm panel.
• External pushbuttons may be used to adjust the display brightness.
• If connected to a central dimming facility, the NAVIKNOT 600 SE may
receive dimming commands via a serial data connection.
• An external selector switch may be used to activate or de-activate
the double-ended ferry mode. In this mode, the NAVIKNOT 600 SE
displays and transmits all speeds with the sign reversed.
2.3 Power-up Sequence
The individual components of the NAVIKNOT system are not equipped
with power switches. All devices power up simultaneously, as soon as
supply power is applied to the system.
Upon power up, the startup routine is executed:
The startup screen is shown and a
system test sequence is executed.
A status line at the bottom of the
screen indicates the progress and
results of the following tests:
RAM test
I/O test
Checksum test
Setup Data test
After the system test, the indication
“waiting for main unit” may be
briefly shown at the CDU, while the
Electronics Unit initializes itself.
As soon as the system is fully oper-
ational, the actual speed over
ground, the GPS signal status and
the daily and total mile counters are
displayed.

Note Should the NAVIKNOT electronics fail to establish communication with
the CDU(s) after power-up, the indication “waiting for main unit” will be
shown permanently at all connected CDUs. An audible alarm is sounded
which must be locally acknowledged at each CDU.
The NAVIKNOT system will not operate properly until the cause of failure
is eliminated and should be powered down until it can be serviced.
