Query to adjusted configuration
Syntax command:
$AA2 cr
Response:
!AATTCCFF cr
symbols correspond with paragraph
"Configuration of transducer"
Reading of device name
Syntax command:
$AAM cr
Response:
!AAT4311 cr or
!AAT4411 cr
(accordingly with transducer
model)
Reading of firmware version
Syntax command:
$AAF cr
Response:
!AA(version) cr
reads version number of transducer
firmware
Error states
>-0000 cr
lower limit of temperature
>+9999 cr
upper limit of temperature
Example 1:
Change of transducer address during operation (without closed jumper, CRC switched
OFF)
Transducer, which had address 23h is configured to address 24h, speed 9600 Bd,
without CRC, setting of communication speed and CRC must not change (setting of
communication speed and CRC is not possible to change without closed jumper).
Command:
%23242B0600 cr
Response:
!24 cr
Example 2:
Reading of temperature from transducer without closed jumper, address of transducer
01h, without check sum.
Command:
#01 cr
Response:
> +020.50 cr
with check sum:
Command:
#01 84 cr
where it is sent:
23 30 31
38 34
0D
calculation of CRC: 23h+30h+31h = 84h, then CRC =
84
h, it is sent as
0x38, 0x34
Response:
>+020.50 8E cr
where it is sent:
3E 2B 30 32 30 2E 35 30
38 45
0D
calculation of CRC: 3Eh+2Bh+30h+32h+30h+2Eh+35h+30h=18Eh tedy CRC =
8E
h, then it is sent as
0x38, 0x45
Example 3:
Setting of transducer to address 9F, communication speed remains 9600 Bd, check
sums are switched ON (jumper should be closed because setting of CRC will be
changed):
- with jumper, transducer always reports from address „00“ without CRC
Command:
%009F2B0640 cr
