14.2.2 Input Data
The input data consists of modules that have a fixed position in the data field. There are two types of
modules: <Box data> and <Data for one head>.
Module <Box data> consists of one byte in which bit0 gives the trigger state (configuration 0x12).
Module <Head data> consists of two bytes object temperature and two bytes head temperature
(configuration 0x51). The format is 1/10 °C/°F.
Box data: Internal temperature
Head 1: Object temperature
Head 2: Object temperature
Head 3: Object temperature
Head 4: Object temperature
Head 5: Object temperature
Head 6: Object temperature
Head 7: Object temperature
Head 8: Object temperature
The slave expects one <Box data> module configured at the first position, followed by <Head data>
modules. Any other configuration will cause a configuration error.
The input data length gets calculated from the count of configured modules. So, if only one head is
connected and configured then only seven bytes are transferred. If all heads (maximal eight) are
connected and configured then 35 bytes are transferred. If only one head is connected but eight heads
are configured then also 35 bytes are transferred.
