Receiving Data From The Meter
(T), a block print request command (P) or a User Input print request. The
response from the meter is either a full field transmission or an abbreviated
transmission, depending on the selection chosen in Module 5.

counter value, an * (used as an overflow character) replaces a space in byte 7.
Byte 8 is always a space.
Sending Serial Commands and Data

command character, a value identifier, numerical data (if writing data to the
meter) followed by a command terminator character, * or $.

Meter Response Examples:
1. Node address = 17, full field response, Cycle Counter = 875
2. Node address = 0, full field response, Setpoint On value = 250.5
3. Node address = 0, abbreviated response, Setpoint On value= 250, last line of

Command String Examples:
1. Node address = 17, Write 350 to the Setpoint On value
2. Node address = 5, Read Timer value, response time of 50 msec min
3. Node address = 0, Reset Setpoint output
4. Node address = 31, Request a Block Print Output, response time of 2 msec min
Transmitting Data to the Meter
Numeric data sent to the meter must be limited to Transmit Details listed in the
Register Identification Chart. Leading zeros are ignored. The meter ignores any
decimal point and conforms the number to the appropriate display format. (For
example: The Timer range is set for tenths of a second and 25 is written to the
Timer Start register. The value of the register is now 2.5 seconds. In this case,
write a value of 250 to equal 25.0 seconds).
Note: Since the meter does not issue a reply to value change commands, follow
