Using RST825 SatRADIO
The
RST825
is a fully self contained standalone portable Radio over Iridium Satellite system
in a rugged carry case. It has its own battery supply for over 50 hours operation, with
external power input for longer term use. The carry case is a quick deployment solution with
all that is required contained within the case.
The
RST825
is software configurable to operate in a number of ways to best suit your
situation. Most relates to how the satellite call is initiated.
•
Auto-answer. Regardless of any locally initiated call out operation, the
SatRADIO
can be setup to auto-answer an incoming call. Once answered the remote caller
participates in the local radio net.
•
Manual-answer. An incoming satellite call causes an intermittent ring tone to be
transmitted out to the local radio group. Any member of the local group can answer
the call by sending a DTMF-0.
•
Auto-dial last number. When the
SatRADIO
and the radio are both on, the unit will
immediately try to call the last number that was dialed on the Iridium handset. This
mode is most useful for emergency services where a quick and easy method of
connecting the local net to central command is required. If the call ever drops out,
the
SatRADIO
will attempt to redial the number again.
•
Auto-dial fixed number. In cases where only one remote number is ever to be called,
instead of calling the last dialed number, the unit can always dial a user-preset
number.
•
Manual-dial. Any member of the local group can request a satellite call using DTMF
dialing on the radio handset. A user PIN entry (default 9876) is required prior to the
phone number entry to add security. A manual call can be hung-up either at the
remote end, or by sending DTMF-0.
•
Manual-quick-dial. Similar to manual dial, except that a quick dial number is called
instead of the full phone number. 10 quick dial numbers are available and are called
by using the sequence PIN 0->9,*, to select the number.
•
Handset Call. When auto-dial switch is off, or Radio is Off, the Iridium handset can
be used to make a satellite call. Audio is routed to the handset rather than the radio
channel.
The
SatRADIO
always give priority to the local group communications. If a local user is
transmitting at the time, even if the remote person speaks, the
SatRADIO
will not key up the
transmitter till the local person stops transmitting.
