Table 11.24. Serial Time (“SER TI”) Values
VALUE FUNCTION
0
Transmit at each reading cycle
1 to 59999 (decimal) Transmit using this interval (in
seconds) between transmissions
EXAMPLE: You want to configure RAM such that you get a print out of certain items every hour. This
corresponds to an interval of 3600s=E10 Hex. Send the command *15P1E0E10. The meter will respond
with 151E.
11.28 Recognition Character
This item is a 1-byte Hex value. The recognition character is the first transmitted character in a command string.
It ensures that the corresponding command is read by the correct meter. It uses the prefixes G, P, R, and W
with the suffix 24.
Characters with an equivalent Hex value of 0 to 20, and 80 to FF are not allowed. Also, the caret (^), the capital
A, and the capital E are not allowed.
EXAMPLE: You want to change the recognition character of meter #15 from the asterisk (*) to the point symbol
(#). The hex value of # is 23. Send the command *15P2423. The meter will respond with 15P24.
The recognition character is now # and the meter will not respond to any other character.
11.29 Units Of Measure
There are two units of measure items. Each is a 3-byte Hex value using he prefixes R and W. Unit 1 uses
suffix 2C and Unit 2 uses the suffix 2D.
Unit 1 pertains to BATCH, BAT NO, RATE or AVG RT values.
Unit 2 pertains to TOTAL values.
Units 1 and/or 2 are transmitted after the corresponding value if they have been enabled by a DAT FT bit.
EXAMPLE: You are in Rate Mode and want Unit 1 and Unit 2 to be GPM and GAL, respectively. Looking at
the ASCII table in Section 4-5, you see that GPM corresponds to a Hex value of 47504D; GAL corresponds to
Hex value of 47414C. To configure GPM units of measure, send the command *15W2C47504D. The
meter will respond with 15W2C. To configure GAL units of measure, send the command
*15W2D47414C. The meter will respond with 15W2D.
11.30 TX/RX Turnaround Delay (SERIAL DELAY)
This item is 1 byte (2 characters). It controls the delay time between the end of one transmission from the host
to the start of response from the meter. It uses command prefixes G, P, R, and W with the suffix 25.
Table 11.25 shows the bit assignments.
