8.4 ASCII INPUT

The meter receives commands and setup data. The meter may receive one of 8 commands: P,
G, W, R, V, SC, SG, and SP. Each of these commands are explained in detail in the following
pages. Each is a single letter preceded by the preamble string of the following 3 characters:
@U?. For example, Put reads @U?P. The @ U and ? characters reduce the probability of noise
patterns and aid in generating an acceptable command. The Put command is followed by 42 hex
characters of desired setup data. All commands are terminated with a carriage return, indicated
by <CR>.

'Put' Command @ U?P (setup data) <CR>
Sends setup data to the meter. The meter then stores data into its active memory and starts
making measurements using the new setup parameters.
'Get' Command @ U?G <CR>
Sends the current setup parameters from the meter's active memory to the computer. Use the
'Get' command after the 'PUT' command to verify that the meter has correct setup parameters.
