b) The answer (if an error occur):
ADDR FUNC ERROR CRC L,H
01 83 60 41 18
ERROR - error code = 60h, bottom border of the measurement range is exceeded
2. Read of device ID code
ADDR FUNC REG H,L COUNT H,L CRC L,H
01 03 00 21 00 01 D4 00
The answer:
ADDR FUNC BYTE C DATA H,L CRC L,H
01 03 02 22 F1 61 60
DATA - identification code (22F1h)
3. Change of the device address from 1 to 2 (write to reg. 20h)
ADDR FUNC REG H,L DATA H,L CRC L,H
01 06 00 20 00 02 09 C1
DATA H - 0
DATA L - new device address (2)
The answer (the same as the message):
ADDR FUNC REG H,L DATA H,L CRC L,H
01 06 00 20 00 02 09 C1
4. Change of baud rate of all devices connected to the net (BROADCAST message).
ADDR FUNC REG H,L COUNT H,L CRC L,H
00 06 00 22 00 04 29 D2
DATA H - 0
DATA L - 4, new baud rate 19200 baud
Device do not reply to BROADCAST-type messages.
