Special notes for the A733GSM RTU

3. Raise the holder top and slide the SIM card into it (Fig. 4, center).

4. Snap the holder top back on and slide it back as shown again by the red arrow

depicted in Fig. 4, right.

5. Mount the lid back, taking care that the rubber gasket sealing the box is not out

of place and free of dust or dirt.

WARNING: Be sure to mount the rubber gasket properly, so that the unit’s IP65 environmental

protection is not affected.

6. Screw the four screws back in, applying a moderate force, tightening

crosswise.

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

means of a PIN code. You will find this code in the package that you got from your

cellular service provider.

In order to be able to activate your card, the A733GSM must be properly powered.

As the RTUs are delivered from the factory with the batteries uncharged (they have

a longer shelf life in this state) you will need to charge the batteries first. The best

way to do this is to attach the solar panel to the power connector and expose the

RTU to the 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 for at least four hours or more of

charge.

To enter the PIN code you will also need a serial adapter cable; this can be

obtained from Adcon Telemetry or your reseller. Proceed as follows:

1. Connect the serial cable between the COM port of your PC and the RTU.

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 on this issue you may want also to check the section “Communicating

with the RTU” on page 21.

2. Make sure that you can communicate with the RTU by pressing the enter key:

the device will answer with its own ID number and a hash sign (#).

3. Now type the command GSMPIN nnnn (where nnnn is the PIN code) and

press enter; if the PIN was correct, the RTU will answer id gsmpin 0, where id

is its ID number.

This completes the PIN entry procedure. You can check the status of the

A733GSM RTU by typing at any time the command GSMSTAT. This command

returns a list of GSM parameters:
