COMMUNICATION PROTOCOL
Notes:
1. (CR) stands for Carriage Return. Its ASCII code is
0DH. (LF) strands for Line Feed. Its ASCII code is 0AH.
2. “d” stands for a digit number of 0~9. 0 is expressed
as +0.00.
3. “d” stands for a digit number of 0~9. The number
before “E” is integer.
4. Working status code, 1-6 letters. Refer to Table 5.2
for error code.
5. “s” is “ON”, “OFF” or “UD’”. For instance, “TR:ON,
RL:UD” means that the OCT is in closed state and
RELAY is not used.
6. @ stands for key value. For instance, value 30H
means key “0”, command “M4” is equivalent to press
key “4”.
7. “a” stands for current value, a digit number of 0~20.
For instance, A02.34, A00.2
8. “dddddddt” stands for 8-digit electronic serial
number. “t” stands for flow meter type.
9. If there are more than one flow meters in a network,
all the basic commands must be prefixed with N or W.
Otherwise, multiple flow meters may reply to the same
request.
10. Adding a GSM module to the flow meter allows the
user to check flow meter flow rate and other parameters
from a cell phone.
11. Used for visiting the printer buffer content.
6.2.2 PROTOCOL PREFIX USAGE
1) Prefix P
The prefix P can be added before any command in the
above table to have the returning data followed with
two bytes of CRC check sum, which is the adding
sum of the original character string.
Take command DI+(CR) (Return POS Totalizer Value)
as an example. The binary data for DI+(CR) is 44H,
49H, 2BH and 0DH. Assume the return value of this
command is +10m3(CR)(LF) ( the string in
hexadecimal is 2BH, 31H, 32H, 33H, 34H, 35H, 36H,
37H, 45H, 2BH, 30H, 6DH, 33H, 20H, 0DH, 0AH).
Then, the P-prefixed command, PDI+(CR), would
