6.3.11 Detailed Description of Connections, fuses, factory reset etc…
1 The RS-232 terminals is only for factory use
2 The upper right preset button can be used to restore factory
settings at two levels. It is assumed that no SD card is present in
the transponder SD card reader.
a. To reset the IP settings for the transponder and the connection
to the display to default values if these setting have been
reconfigured and are unknown:
Press the upper right preset button and apply power. Keep the
button pressed until the alarm LED starts flashing after approx.
10 seconds. Then release the button immediately.
The IP settings are now reset to factory default.
b. To restore the complete factory setting, all programmed
parameters are lost:
Press the upper right preset button and apply power.
Keep the button pressed.
Watch the alarm LED carefully, after approx. 10 sec it should
start flashing for 5 seconds and then stop. After some seconds
it will flash a sequence rapidly.
The preset button should now be released, and the factory
settings are now restored.
3 There are two fuses connected in series with the Main and
Backup power. There is no visual indication on fuse failure, but a
quick voltage measurement on each side of the fuse should give an
indication. If a fuse is blown, consider possible reasons for fuse
failure and replace the fuse if the reason for failure is repaired.
Replace fuses with identical fuses only. Use of other fuses or such will
make all warranty void.
4 The SD card reader is used for Software upgrades only. This must
be performed by Simrad trained Dealers/Distributors/Service Agents
5 The RST button is used to reset the almanac data of the internal
GPS in case of error. In order to reset the almanac, power off the unit
and then press the RST button for approximately 2s. When you
power up the unit again, the internal GPS will use some time to
obtain a fix. Approximately up to 15 minutes.
6 The GPS-Antenna Voltage jumper is used to select phantom feed
for an active antenna either 5 or 3.3 V. The maximum recommended
current drawn from these ports is 50 mA.
7 The termination jumpers for the sensors, external display, pilot
terminal and DGNSS beacon are made available in order to lower the
differential input resistance of the port in order to enable for longer
cables. The differential input resistance is approximately
7700 Ohm
without jumper and 240 Ohm with the jumper
connected.
