Byte 1 (Least) = seconds, Max 59
Byte 2 (Middle) = minutes, Max 59
Byte 3 (Most) = hours, Max 99
EXAMPLE: You want to assign TIME of meter #15 to 7:25:30. Send the command *15P2807191E<CR>.
2. BATCH count, BAT NO, and TOTAL. BATCH count and TOTAL are 4 bytes each, and BAT NO is 3 bytes.
There is no decimal point for these items. The sign bit is the most significant bit of each item (0 for positive and
1 for negative). Therefore, max and min values for BAT NO are ±(7FFFFF) ±Hex=8,388607, and min values for
Batch count and TOTAL are ±(7FFFFFFF) Hex = ±2,147,483,647.
EXAMPLE: You’re in Batch Mode and want to read BATCH count, BAT NO, and TOTAL. Send the following
commands:
BATCH: *15G2A<CR>. The meter responds with 15G2A003050<CR>.
BAT NO: *15G2B<CR>. The meter responds with 15G2B000038<CR>.
TOTAL: *15G29<CR>. The meter responds with 15G29000D0190<CR>.
Since the meter is in ECHO and Multipoint modes, the first 5 characters comprise the ECHO response.
The BATCH Hex value 003050 = 12368 in decimal.
The BAT NO Hex value 000038 = 56 in decimal.
The TOTAL Hex value 000D0190 = 852368 in decimal.
11.22 Baud Rate (“BAUD”)
This item is 1 byte (2 characters). It specifies the communication rate over the bus. It uses prefixes R and W
and the suffix 19. Table 11.20 shows data values and their corresponding baud rates.
Table 11.20. Baud Rate (“BAUD”) Data Values
DATA VALUE BAUD RATE
0 300
1 600
2 1200
3 2400
4 4800
5 9600
6 19200
EXAMPLE: You want to set the baud rate of meter #15 to 9600. Send the command *15W1905<CR>. The
meter responds with 15W19<CR>. You should then reset the meter with *15Z05<CR>. The meter will respond
with 15Z05<CR>.
11.23 Serial Communications Configuration (“SER.CNF”)
This item is 1 byte (2 characters). It uses prefixes R and W with the suffix 1A according to Table 11.21.
