Table 3.5.4:
Transmitting the actual Tx activate times
Explanation of the bytes transmitted by the module:
Byte 1...
The first byte always returns the contents of the received command byte
(here always $04).
Byte 2...
The second byte returns the contents of the received sub command. The sub command
designates the selected identifier.
Byte 3,
Byte 4...
In these two cells the actual Tx activate time is returned (see also 'parameter 1 and 2').
