EXAMPLE 3
Multiple commands reading for registers (hexadecimal command 3, h03):
Assuming that we wish to read the two gross weight values (in the example 4000) and net weight
values (in the example 3000), reading from address 40008 to address 40011 must be performed
by sending the following string:
h01 h03 h00 h07 h00 h04 hF5 hC8
The instrument will respond with the string:
h01 h03 h08 h00 h00 h0F hA0 h00 h00 h0B hB8 hB3 h30
