Not all receivers are able to handle the antenna voltage from the DELTA 200S without producing
interference. Therefore the output level of the corresponding wideband output can be reduced by
adjusting the associated trimmer potentiometer counter-clockwise until the reception is clear again.
Installation of plug-in modules
Two plug-in modules can be inserted into the distribution box AV 205. For retrofitting of plug-in
modules, open the AV 205 case. The plug-in modules have 2 connection pins on one side and 3 pins
on the other side. Insert the plug-in module into the sockets of the AV 205 main board with the 3 pin
end of the module at the output side of the AV 205. Then close the AV 205 case and identify the
association on top of the AV 205 cover using a waterproof marker.
To guarantee a perfect working antenna it is mandatory to do the installation in a workman-
like manner.
Any faults caused from neglecting these instructions are excluded from the manufacturer's
warranty.
In case of doubt consult a specialist.
Trouble shooting of antenna system HAWAII 4G
1.
No function of instruments connected to the AV 205
1.1.
Check if the green indicator lamp of the AV 205 lights.
1.2.
Check both fuses inside the AV 205 (0.5 A medium blow; 5 × 20 mm and 0.16 A fast blow,
5 × 20 mm).
1.3.
Check the AV 205 supply voltage: 12V to 28V.
1.4.
Disconnect the antenna cable from the AV 205. Measure the output voltage at the antenna
terminal of the AV 205: 11.5V to 12.5 V.
1.5.
Check the AV 205 supply current:
- Without antenna connected and without plugin modules: 20 mA to 55 mA.
- With antenna connected, without plugin modules: 120 mA to 175 mA.
Additional supply current for plugin modules:
BBII: 80 mA +/- 2 mA
BBAM: 40 mA +/- 2 mA
Navtex: 35 mA +/- 10 mA
DGPS: 22 mA +/- 5 mA
1.6.
Measure the resistance of the antenna cable incl. antenna with an Ohmmeter: 15 Ohm to
100 Ohm.
1.7.
Output 1 or 2 not working: replace the plugin module for the particular output.
1.8.
If the instrument is connected to output 3 or 4 or to a plugin module BB at input 1 or 2, check
if the trimmer potentiometer associated with the output is turned on.
1.9.
Check the cable between AV 205 and the instrument for short circuit or break.
1.10.
If the instrument has several antenna inputs, assure that the correct antenna input is
selected at the instrument.
2.
No function of mobile telephone / router / modem
2.1.
Check if the ship is in the operation range of a base station of the mobile network - some
mobile networks have a range limited by system.
2.2.
Check the cable between the mobile telephone / router / modem and the AV 304 for short
circuit or break. For that the cable has to be disconnected at the AV 304 and at the mobile
telephone / router / modem.
The antennas, the distribution boxes and the plug-in modules may be repaired by
authorized specialists only!
