Reading ambient
temperature:
AAut
Output: stored value, 4-digit hex
e.g. 0258 corresponds to 600 degrees
Entering ambient
temperature:
AAutXXXX
XXXX = value of ambient temperature, 4-digit, hex
XXXX e.g. FFEC corresponds to –20 degrees
- 99
dez
= FF9D
hex
means: automatic, no manual
compensation
Marginal values for ambient
temperature:
AAut?
Output: marginal values for the entry, 2 x 4-digit, hex
e.g. FF9D0384 corresponds to -99 to 900 degrees
Reading maximum/minimum
values:
AAmi
Output: 0 or 1
0 = maximum value, 1 = minimum value
Setting maximum/minimum
values:
AAmiX
X = desired setting
0 = maximum value, 1 = minimum value
Reading marginal values:
AAmi?
Output: marginal value for entry, always 01
Serial number:
AAsn
Output: XXXXX (5-digit decimal)
Device model / software
version:
AAve
Output: XXYYZZ (6-digit decimal)
XX = 70 (IN 5 plus)
71 (IN 5/5 plus)
YY = month of the software version
ZZ = year of the software version
Note: the letter “l” means the lower case letter of “L”.
1)
After entering these commands the device carries out an automatic reset. The device needs
approx. 150 ms before it is ready to use and work with the changed settings.
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 latest.
3. If there is no response, there is a parity or syntax error and the inquiry has to be repeated.
