Installing the SIM card in the A733GSM/GPRS RTU
2. Locate the SIM card holder and open it by sliding it as indicated by the red
arrow (see Fig. 4, left).
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. Remount the lid, taking care that the rubber gasket sealing the box is not out of
place and is free of dust or dirt.

:
Be sure to mount the rubber gasket properly, so that the unit’s IP65 environmental
protection is not affected.
6. Put the four screws back in place, applying moderate force (approximately 150
to 200 Ncm), tightening crosswise. For additional information, please contact
Adcon Telemetry or your local reseller of Adcon Telemetry products.
This completes the SIM-card installation. Now you will need to activate the card by
using a personal identification number (PIN). You will find this number in the
package that you got from your cellular service provider.
Before you can activate your card, the A733GSM/GPRS 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 must 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 at least four hours for charging.
You need a serial adapter cable to enter the PIN; you can get the cable from Adcon
Telemetry or your reseller. When you have the cable, you can proceed as follows:
1. Connect the serial cable from the COM port of your PC to 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, see
“Communicating with the RTU” on page 27.
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. Type the command GSMPIN nnnn (where
nnnn
is the PIN code) and press
enter. If the PIN is conforming to the standard PIN format requirements the
RTU will answer
id
gsmpin 0, where
id
is its ID number (this is NO PIN check
with your provider!).
This completes the PIN entry procedure. You can check the status of the
A733GSM/GPRS RTU at any time by typing the
GSMSTAT
command. This
command returns a list of GSM parameters:
