SENDING SERIAL COMMANDS AND DATA
command character must be constructed. A command string consists of a
command character, a value identifier, numerical data (if writing data to the
meter) followed by a the command terminator character * or $. The <CR> is
also available as a terminator when Counter C is in the SLAVE mode.

procedure details construction of a command string:
1. The first characters consist of the Node Address Specifier (N) followed by a

Command String Examples:
1. Address = 17, Write 350 to Setpoint 1
2. Address = 5, Read Count A value, response time of 50 - 100 msec. min.
3. Address = 0, Reset Setpoint 4 output
Transmitting Data To the Meter
the Register Identification Chart. Leading zeros are ignored. Negative numbers
must have a minus sign. The meter ignores any decimal point and conforms the
number to the scaled resolution. (ie. The meter’s scaled decimal point position
is set for 0.0 and 25 is written to a register. The value of the register is now 2.5.
In this case, write a value of 250 to equal 25.0).
Note: Since the meter does not issue a reply to value change commands, follow
Transmitting Data From the Meter

from the meter is either a full field transmission or an abbreviated transmission.
The meter response is established in Module 7.

unit address field. The next three characters (bytes 4 to 6) are the register
mnemonic. The numeric data is transmitted next.

(used as an overflow character) replaces the space in byte 7. Byte 8 is always a
space. The remaining ten positions of this field (bytes 9 to 18) consist of a minus
sign (for negative values), a floating decimal point (if applicable), and eight
positions for the requested value. The data within bytes 9 to 18 is right-aligned
with leading spaces for any unfilled positions.

22), and <LF> (byte 23) are used to provide separation between the transmissions.

Meter Response Examples:
1. Address = 17, full field response, Count A = 875
2. Address = 0, full field response, Setpoint 2 = -250.5
3. Address = 0, abbreviated response, Setpoint 2 = 250, last line of block print
