4.5.7 Set slave address (48h)
This function allows to set a slave addresses of the particular transducer in case that multiple
transducers are connected to the same bus. The function is intended to be transmitted as a
query with universal service address 248. The serial number and the desired slave address are
transmitted as parameters of the function in the data filed. If any of the connected transducers
finds that its own serial number is equal to the serial number transmitted in the query, it sets
its own slave address to the value transmitted in the query and responds to it. The other
transducers do not perform any action and do not generate any response
Here is an example of broadcast which requires the transducer with serial number 00010285h
to set its own slave address to 07h.
Byte no.
