Ethernet output data types are classified into two types: “Short data” and “Long data”.
Set a data type with a Web server function. ([Device Setup] – “Data length Type”)
Long Data is short data added by extension region of 24bytes (Transmitter-specific data, etc.). When using the
extended region, please set to “long data”.
When not using the extended region, it is recommended set to “short data”.

Transmitter ID number
ID number 10 digit is converted to ASCII data(Hexadecimal).
Example) ”010100004A”

Checksum
Calculated XOR from “Transmitter ID” to “ETX”. And it is
converted to ASCII data for 2byte.
