Figure 158 PTTP DATA ACK packet format
The destination and source address are the server and client MAC addresses respectively.
The Type1 field indicates this is a data ack packet. Next to this field, it is the acknowledged data block number.
12.2.5.4 Translation Table DATA format
The Translation Table data follows a specific format. It is a set of one or more parameter items. A parameter item is
defined as follows:
Size
TT Parameter Item (4 + n bytes)
ParameterCode Index
ParameterValue
1 byte 2 bytes
1 byte
0 ... n bytes
Figure 159 Translation Table parameter item
The field Size is the number of bytes of the rest of parameter item (ParameterCode + Index + ParameterValue).
The minimum value is thus 4. If the value is 0, it means that no more parameters are sent. It is mandatory to finish
the Data block with a 0-size byte.
The ParameterCode is a 2-byte field. The first byte is reserved for future extensions. It defaults to 0x00. The second
byte is the parameter code. The whole field identifies one and only one parameter.
The Index byte contains the index for list parameters (from 1 to 127). It is 0 for scalar parameters.
The ParameterValue contains the value for that parameter. Its format depends on the ParameterCode and may be of
any type such as int8, int16, int32, string…
