Example - Satellite Phones
A satellite phone is treated like a PSTN modem by the RTU and can be used on any serial port. The
following setup is for a Motorola 9522 satellite phone.
• First ensure that the latest firmware supporting Satellite Phones is loaded in the RTU (as detailed in
protocols.pdf available from www.cse-semaphore.com/mykingfisher).
• When a satellite phone is first obtained, it usually requires a PIN number to boot up (if this has not
already been disabled). Use AT+CPIN? to check if it needs a PIN. To set the PIN number use
AT+CPIN="1111"<CR> (1111 is the default PIN number). The command AT+CLCK="SC",0,"1111"<CR>
should then be used to disable the need for a PIN number.
• The satellite phone antenna must have a very clear view of the sky and not be near any buildings or
objects (it should have a 150 degree uninterrupted view of the sky). Use AT+CSQ to query signal
strength. This will return a number in the range 0-5 where 3-5 is good.
• Configuration, Port List: Set the port Type to PSTN, Pre Tx to 20,000 ms. Select the Configure button
to set the initialisation string. Use the default string for an external modem (AT&FTE0V0S0=2&W). Note:
a Pre TX delay of 20,000 ms must be used as the satellite phone uses the off hook signal to set carrier
detect. The satellite phone signals that a carrier is detected and that it is online before the handshaking
has occurred with the remote modem. Configuring a Post Tx delay of 20,000ms forces the RTU to wait
for 20 seconds before attempting to send a message.
• Configuration, Network List: Set Target RTU to the address of the RTU to dial and Port # to the port
number configured above. The default Timeout of 2000 ms can be used. Note: a network link is not
required if the RTU is only answering calls.
• Configuration, Phone Directory: Set Primary Phone Number and Secondary Phone Number to the
phone number of the target RTU to dial. Note: the phone directory does not have to be configured if the
RTU is only answering calls. The international dialling code for a satellite phone to dial out is 00 <country
code><area code><phone number>. The prefix 00 is always needed by a satellite phone when dialling a
phone number. Eg. to dial Semaphore (Australia) use 00 61 3 8544 8544 where 61 is the country code
and 3 is the area code.
• Configure a communications block (eg. RX_DATA) in ladder logic to communicate with the target RTU.
The RTU will then automatically dial the number configured above.
SMS Pager Messages: A satellite phone can send pager messages to the Telstra PET SMS service. In the
Pager Configuration window, set Phone No. to 00 61 439 125107 (the international Telstra SMS Access
Manager phone number). The satellite phone can currently only send SMS messages directly to other
satellite phones.
Dialling A Satellite Phone: Each satellite phone has a data number and a voice number. An RTU uses the
data number. To dial the satellite phone from Australia use 0011 <satellite phone data number>. Eg. 0011
8816 123 45678 where 0011 is the international dialling code when in Australia and 8816 123 45678 is the
satellite phone data number.
Communicating With A GSM: Dialling a GSM modem using a satellite phone is unreliable and not
recommended.
