12. Connecting to the WiFi module’ server with a remote client is now possible.
By default, the WiFi module is configured as an RS232 to WLAN tunnel for serial communication.
In the indicator configuration, the port's Baud, Bits, and Parity settings must remain at their default settings of
9600 (Baud), 8 (Bits), and None (Parity) in order for the indicator to work with the WiFi module. Other settings, such
as the port's Function, Echo, and Response can be changed as needed.
13. Using a Terminal Emulation program, such as Putty, as a remote client connection to the WiFi module’s server over
Telnet is possible using the IP Address that was noted in Step 11 on page 8 and the Local Port number, which by
default is 10001.
Figure 7. Putty Example
If the card's IP address changed and there is no longer access to the card through the location’s wireless network,
connect to the Soft AP and use the Web Manager to learn the new IP Address.
If the Web Manager cannot be reached through the location’s wireless network or the Soft AP, the card needs to be
defaulted. See WiFi Module Default Procedure on page 4.
