W5500S2E serial to Ethernet module
W5500S2E user manual
51
Reconnection Time (ms):
reconnection interval, only effective in TCP client mode,
default: 0 (instant reconnection), value range: 0 to 60000, unit: ms
Inactivity Time (ms):
Set the Inactivity timeout, only effective in TCP modes, value
range: 0 ~ 60000, unit: ms, default: 0 (disable)
Keep Alive Time (5s):
Set the Keep alive timer, only effective in TCP modes, value
range: 0 ~ 65536, unit: 5s; default: 0 (disable)
Verify the Connection
: When the user created a communication in TCP and this
command was enabled, the module requires a password confirmation from the Ethernet
side. If the password is wrong, it requires re-entering password until it receives a correct
password. Default: No (disable)
Send Hello Message
: Define message sent when TCP connection succeeds. Selections
includes: “None”, “Send Device Name”, “Send MAC Address” or “Send IP Address”.
Default: “None” (disable)
Connection Condition
: In TCP client mode, this function can set as “Connect socket
after power up” (default) or “Connect socket after UART received data”
Clear Buffer if Connect
: Data may be left in the serial buffer in case of disconnection.
Enable this command clears the buffer when establishing TCP connection. Default:
uncheck (disable)
Debug Message Enable
: This will enable debug message sending to the serial interface.
Thus, this option may help users more easily through serial terminal software manually.
Default: checked (enable)
AT Echo Enable
: Echo means WIZS2E module could directly return the input values to
the serial interface. Thus, this option may help some users working more easily through
serial terminal software. However, this may cause trouble if the serial is connected to an
embedded system. Turning off this function may help. Default: checked (enable)
