8.6 WSNConfig Program Operation
WSNConfig.exe provides a number of useful functions in addition to those covered above. WSN-
Config.exe can be run separately or at the same time as the customer’s application program to provide
WSN802G module configuration support. WSNConfig.exe configuration commands run on Port 161, and
WSNConfig.exe listens for SNMP commands on Port 162. The application (sensor server) runs on Port
8255 by default. When active, the customer program runs as the sensor server. Only one program at a
time can run as the sensor server. WSNApp.exe on the Kit CD is an example customer application pro-
gram.
Figure 8.6.1
Double clicking on a module IP address in the left text box of the main WSNConfig frame launches a mul-
ti-tab configuration dialog box for the module, as shown in Figure 8.6.1.
All tabs in this
Config
dialog frame have
Refresh
,
Get All
,
Apply, Default
and
Reboot
buttons. WSNCon-
fig.exe maintains a local buffer that holds a copy of all MIB configuration parameters (see Table 7.3.1).
Clicking the
Refresh
button loads the configuration parameters from the local buffer into various tabs in
the
Config
dialog box.
Clicking the
Get All
button queues a request to the WSN802G module to send a new copy of all its con-
figuration parameters. How quickly the module responds depends on the
ConfigTrapInterval
system pa-
rameter and when in the trap interval the request was queued. As a new copy of the configuration param-
eters is received, the local buffer is updated. Clicking the
Refresh
button after the local buffer is updated
will, in turn, update the data in the various tabs in the
Config
dialog box.
Clicking on the
Apply
button followed by clicking on the
Reboot
button will queue a request to the
WSN802G module to modify parameter values that have been changed in a
Config
dialog tab and to
reboot to use the parameter changes. Again, how quickly the module updates parameter values depends
on the
ConfigTrapInterval
system parameter and when in the trap interval the request was queued.
