Table 10.32. Data Format (“DAT FT”), Bits 7, 6, 5, and 4
BIT NUMBER
7 6 5 4 SELECTS
x x x 0 Don’t send PEAK value
x x x 1 Send PEAK
x x 0 x Don’t send VALLEY value
x x 1 x Send VALLEY
x 0 x x Use space as separator
x 1 x x Use as separator
0 x x x Don’t send units of measure
1 x x x Send units of measure
EXAMPLE: If you don’t want PEAK, VALLEY or units-of-measure and do want just between Alarm Status
Character, the unfiltered measurement and the filtered value, the MSN above is “0” and the LSN is “9”, so the
command to meter #15 HEX is “*15W1B09”.
This puts this format into EEPROM; to move this into RAM for immediate use, also send “*15Z04” (Hard
Reset).
10.19 Communications Bus Format (“BUS FT”)
The “1C” command suffix data is the byte of “BUS FT”, programmed in Appendix A.
“x” is used to show either “1” or “0”.

3 2 1 0 SELECTS
x x x 0 Excludes checksum with reading
x x x 1 Includes checksum with reading
x x 0 x No line feed

x 1 x x Echo response
0 x x x Point-to-point mode
1 x x x Multipoint mode
RS-232 is selected if the most-significant nibble has a value less than 4, and you can select either continuous
data transmission or transmission on command, and either RTS control of each character or each message:
