Adcon Telemetry or your local reseller of Adcon Telemetry

products.

This completes the SIM-card installation. Now you need to activate the

card by using a personal identification number (PIN). This number is in

the package you received from your cellular service provider.

Before you can activate your card, the RA440 must be properly

powered. As the units are delivered from the factory with the batteries

uncharged (they have a longer shelf life in this state), you must

charge the batteries first. The best way to do this is to attach the solar

panel to the solar connector and expose the panel to sunlight for at

least one hour. If the sky is overcast the battery will still charge, but

at a lower rate; in this case allow at least four hours for charging.

To enter the PIN you need a serial adapter cable. If you do not have

one, you can get it from Adcon Telemetry or your reseller. When you

have the cable, proceed as follows:

1. Connect the serial cable from the COM port of your PC to the

solar input of the RA440. Configure your terminal as follows:

• 19200 baud

•1 stop bit

• 8 data bits

• no parity

• no handshaking protocol (neither hardware nor software)

For more details, see “Communicating with the RTU” on page 25.

The unit will display a prompt, which is the unit's ID followed by a

hash sign (#).

2. Enter the command GSMPIN nnnn (where nnnn is the PIN code).

If the PIN conforms to the standard PIN format requirements, the

modem will answer ID GSMPIN #, where the hash mark

represents the modem’s ID number (a zero indicates an invalid

PIN, so check with your provider if you get a zero).

This completes the PIN entry procedure. After a few minutes of

initialization you can check the status of the RA440 at any time by

entering the GSMSTAT command. This command returns a list of GSM

parameters:
