Read signal strength* AAtr Answer: DDDD 4 decimal digit 0000 to 1500
Device type/software
version
AAve Answer: VVMMJJ VV=83
MM=Month JJ=Year of software version
software version AAvs tt.mm.yy XX.YY
tt = day; mm = month; yy = year;
XX.YY = software version
*Read Signal Strength stands for product of emissivity, surface coverage and transmission of the measuring distance.
Note: the letter “l” means the lower case letter of “L”.
Additional instruction for the RS485 interface:
Requirements to the master system during half-duplex operation:
1. After an inquiry, the bus should be switched into a transmission time of 3 bits (some
older interfaces are not fast enough for this).
2. The pyrometer's response will follow after 5 ms, at the latest.
3. If there is no response, there is a parity or syntax error and the inquiry has to be
repeated.
4. After receiving the response, the master has to wait at least 1.5 ms before a new
command can be entered.
