Configuring the USR-WIFI232-602 Serial Port Server
Requires 5 volts to operate (centre pin is positive).
The User Manual can be downloaded from <User Manual>.
When starting the RS232 to WiFi converter for the first time, it acts as a WiFi Access Point (AP) – connect your local PC to the WiFi network it creates (e.g. USR-WIFI232-602_D7AC or suchlike).
With your browser, connect to the default IP address and use the default user-ID and password to access the management screen:
10.10.100.254:8899 (ID=admin PW=admin).
On the unit’s management panel, the ONLY things that need changing are in the first section of the ‘Quick Configure’ screen :
* ‘AP mode’ to ‘STA mode’
* AP SSID: select your local WiFi.
The encryption type and security mode should change to whatever you have in use on your local WiFi network.
* Then type in the Network Key.
Select the ‘Device Management’ menu option. Change the management panel userID and password at this point if you wish and then reboot the RS232 to WiFi unit.
On re-start the unit shuold come up connected to your local network.
If your local WiFi access point is DHCP it will have issued a new IP address to the RS232 to WiFi unit.
Log onto your WiFi access point and look at attached devices – you should see the device connected and you can ascertain the IP address. Go to your web browser and type that web address – you should connect to the RS232 to WiFi unit’s management screen.
Installation and Operation – Fix the local IP address
Configure your WiFi router such that the the RS232-WiFi adapter will always be allocated the same IP address.
Client PC (i.e. where you are running an application that wants to connect to the serial port).
On the PC where you wish to access the serial device, install the virtual serial port software provided by USR: https://www.pusr.com/support/downloads/usr-vcom-setup-software.html
This software, provided by the manufacturer, creates virtual serial ports and can be pointed to the IP address (local or remote) of your serial-port server(s).
