WIZnet supports all various Serial to Ethernet module set-up methods. We also provide Configuration Tool programs and AT commands so that you can set up easily and quickly through the network. To utilize AT command, it can be set up directly from the serial equipment so there is absolutely no need for a PC.
WIZ550S2E supports both methods of set-up. Particularly in the case of using the Configuration Tool program, the foundation is in JAVA so not only Windows but Linux, MAC OS and other systems can also set up and operate it.
AT command’s command frame is easy to understand and simple to use. Every command set starts with “AT” and anything else that doesn’t start with “AT” will get an error. All the command words and parameters are ASCII characters, so if the user wishes to input “AT+NSTAT” the letters ‘A’, ‘T’, ‘+’, ‘N’, ‘S’, ‘T’, ‘A’, ‘T’ and CR(0x0D), LF(0x0A) must be input sequentially. All commands must also end with CR(0x0D), LF(0x0A).
Here at WIZnet, we offer several WIZ550S2E AT command-related tutorials
