10.25.4 EXAMPLE:
Assuming echo mode; no line feed; checksum; and point-to-point mode.
1. Read Block C from EEPROM
a) And send to the meter:
*R42
b) Response from the meter:
1. # of readings between each transmission=2711 (HEX)
2. Alarm Hysteresis=0001 (HEX)
3. Set Pt Hysteresis=0001 (HEX)
4. Lockout #4=E0 (HEX)
5. Lockout #3=3E (HEX)
6. Lockout #2=00 (HEX)
7. Lockout #1=3F (HEX)
2. Write Block C on to EEPROM.
a) Command sent to the meter:
*W42271100010001E03E003F;
b) Response from the meter:
W42
IMPORTANT NOTE: Before sending data to the meter, each nibble of data has to be converted to an ASCII
character.
11. DATA FORMATS ASSOCIATED WITH COMMANDS FOR RATE
METER/TOTALIZERS AND BATCH METERS
This section introduces data formats in detail. The following conditions are assumed in the text and in
examples:
1. The recognition character is the asterisk (*).
2. The meter address is 15 HEX (21 decimal).
3. When any W command is given, a reset is necessary to initiate the command.
4. The meter is in ECHO mode-it echoes the address and Command Index.
11.1 Lockout Bytes (“L1 CNF”, “L2 CNF”, “L3 CNF”)
“G”, “P”, “R”, or “W” followed by “06”, “07”, or “08”, sent to RAM/EEPROM or receive from RAM/EEPROM the 8
bits of each of the three lockout bytes.
EXAMPLE: We want to send a value of “01011010” for L2 CNF into the EEPROM of the meter number 15.
Equivalent HEX value is “5A”, so the computer sends “*15W075A”.
The meter would echo the command with “15W07” if “BUS.3=1”.
Below is the bit pattern corresponding to the lockout bytes.
NOTE: Each Lockout is one byte (8 bits) where:
L1C.1 is bit 0 of Lockout #1
L1C.8 is bit 7 of Lockout #1
Each item on the left will lock out following item on the right.
