Ethernet output data types are classified into two types: “Short data” and “Long data”.
Set the data type with DIP switch of the receiver. For details, refer to the setting of receiver in "Setting".
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”.
Formatting short data (19byte)

Preamble FFH,FFH,FFH 3
STX 02H 1
Transmitter ID number
ID number 10 digit is converted to ASCII data(Hexadecimal).

Fastening information,
test switch battery
information
2 byte ASCII data
Transmission Limit switch signal “01” (30H,31H)
Transmission test switch (Battery voltage OK) “02” (30H,32H)
Transmission test switch (Battery voltage low) “12” (31H,32H)

ETX 03H 1
Checksum
Calculated XOR from “Transmitter ID” to “ETX”. And it is
converted to ASCII data for 2byte.
