inconsistent data length. In order to solve this problem, the data from serial can be
packed according to the specified condition before sending to Ethernet. The condition is
as below.
Time: If there is not any new data during designated time, all data in the serial buffer is
converted to Ethernet packet. If new data is received, the time is re-calculated and
the received data is saved in the serial buffer. Time condition can be utilized when
the serial data size is variable and has no ending character, but needs to be
delivered in frame unit. (If the value is '0', option is not used)
Size: When data is collected as much as the defined size in the serial buffer, it is
transmitted to Ethernet (If the value is '0', option is not used)
Character: The data is collected in the serial buffer until specified character is received,
and transmitted to Ethernet. The character can be specified in Hex formation.
(The value is '0', this option is not used)
One of three conditions is satisfied, the data is transmitted to the Ethernet.
Ex) Delimiter: Size=10, Char=0x0D
Serial data : 0123456789abc
Ethernet data : 0123456789
☞ "abc" data remains in the serial buffer of module.
4) Serial command mode switch code
This function is for module configuration not through network with Configuration tool but
through serial communication. At the default status, the serial command mode is disabled.
When you want to set via serial communication, check "enable".
