6-5. Transmission commands
In this section, examples of transmission using TD Format (BCC) are given.
To transmit using TD Format, remove the checksum from the transmission examples.
These examples are of transmissions with a device with ID number 1.
Example responses are only given for command execution results that have completed properly.
For response data values that are not fixed, numbers are given as “x” and symbols are given as “±”.

Data
The data is comprised of ST1, ST2 and indicator values.
The code returned for ST1 and ST2 uses ASCII 0x80 and later for bit definition, and the lower 7 bits are assigned to status.
Be aware that the valid statuses for ST1 and ST2 vary as follows depending on the bit length setting,
ST1 (8-bit length)
ST2 (8-bit length)
