Response
The Acuvim II series meter response includes the meter address, function code,
quantity of data characters, the actual data characters and error checking. An
example response to read the status of 4 DIs are shown in Table 5-7. The DI
status corresponds to the last 4 bits of the data.
DI1: bit0; DI2: bit1; DI3: bit2; DI4: bit3.
