Upgrading an older A733 GSM
5 APPENDIX
5.1 Upgrading an older A733 GSM
If you want to update an older A733 addWAVE GSM RTU for use with GPRS, first
make sure that the GSM module features the proper firmware. This chapter applies
only to RTUs with WaveCOM GSM-modules (serial numbers below 35.000). To
check the firmware version of the RTU:
−
−
−
60
connect your computer via Adcon A720SC cable to the RTU
type INFO and look for the version number, which must be at least 2.10:
26151 info 0 0 22/3/2006 13:15:17 2.10 ...
enter GSMX at the command prompt
#GSMX
Input will now be sent directly to the GSM modem. Press <ESC> to exit.
Now enter the command
ATI3
The output should be something like
641b09gg.Q2406B 1339080 041604 16:04
The first 3 digits have to be "641" or higher. If not, you need to upgrade the
module firmware. You can also verify that the module is suited for an
upgrade. The "Q2406B" after the period is the module type, which can be
either Q2406B or Q2426B. Other modules such as the Q2403A cannot be
upgraded.
Then enter
at+wopen=2
and you should get
+WOPEN: 2,"AT
v02.10","AT
If one of the version numbers is different, or "AT v02.10" is shown only once,
the IP stack is missing in the GSM module.
v02.10"
