8. Command and Response Structure
NOTES:
1. Each BLOCK is the string of HEX-ASCII data which is produced by the
concatenation of the data for single items listed below:
BLOCK A =
26+17+25+0B+09+08+24+23+22+21
BLOCK B =
1E+1F+20+1A+18+13+12+11+10+05+0C+16+07+1C+1B+0E+0A
BLOCK C =
1D+15+14+04+03+02+01
BLOCKS D, E AND F are meter factory calibration values. Adjustment of these
values should be made with care, preferably using a well-equipped calibration
laboratory.
2. Suffixes 06, 0D, 0F, and 19 are not used: the meter will respond to these with
an error message.
3. The meter, upon completion of a BLOCK PUT (into RAM) Command, goes to
soft reset, “RESEt1”, which does not copy EEPROM data into RAM.
4. Upon completion of a BLOCK WRITE (into EEPROM) Command, however, the
meter goes to hard reset, “RESEt2”, copying the data from EEPROM into the
working RAM. Single PUT (or WRITE) commands do not interrupt the
measurement process of the meter, even when the changes are to scale or
offset values.
5. <data> encoding for W
rite and Put Commands will be described in Section 10
with each R
ead and G
et response.
