5 CONFIGURATION ACCESSORIES
• If possible, send all faxes in a static environment where the
Optus MobileSat S2 has a clear line of sight to the satellite
and is receiving adequate signal strength.
• When performing mobile fax calls try and send when on a
clear open road. Shadowing and loss of line of sight to the
satellite will greatly effect the success of your call.
• Transmission success when using your Optus MobileSat S2
to call another Optus MobileSat S2 while mobile is reduced
due to the increased delay in call setup time. For best
results ensure both telephones are static and have a clear
view to the satellite.
Hints for Receiving:
• Optimise antenna tuning for best received signal strength.
• Configure your fax machine to automatically answer the
incoming call on a minimum number of rings.
• If incoming calls are clearing prior to any fax reception,
disable all header and calling number identification
information on the receiving fax machine.
• Ensure that the sending party is dialling the correct
number for fax.
• If the received fax is illegible and unclear contact the
sender and instruct them to re-transmit the fax with
standard settings and in a static environment with a clear
view to the satellite.
• As a good rule of thumb, ensure your receiving fax machine
has sufficient paper to receive the incoming fax.
Internal GPS
Internal GPS consists of a GPS driver board within the Optus
MobileSat S2 transceiver. This printed circuit board once
connected to the GPS antenna and cable via the GPS
connector (SMA type) will report the global position of the
Optus MobileSat S2. Once the internal GPS has acquired
enough GPS satellite information it will report the position to
the Optus MobileSat S2 handset. It will also report GPS
information to a remote monitoring terminal if connected (See
Remote GPS Monitoring on next page).

5 CONFIGURATION ACCESSORIES
The GPS information can be read from the handset via FCN 24
which displays the longitude and latitude of the Optus
MobileSat S2 in degrees, hours and minutes. (See FCN24 on
Page 100)
External GPS
If the vehicle/vessel already has GPS equipment fitted, this
can be connected directly to the Optus MobileSat S2 via the
DATA & MAINTENANCE port. The external device should be
configured to output its data using the NMEA protocol at
4800bps for best results. Your Authorised MobileSat Dealer
can provide the customised cable for this application.
If the GPS does not update the Optus MobileSat S2, FCN 24 on
the handset will display "No GPS Position Available". The
current GPS information will be displayed after the Optus
MobileSat S2 has detected enough valid GPS data. If the Optus
MobileSat S2 cannot detect the external device, then the "No
GPS connected" will be displayed.
