Analyzer Printout
3.4 Remote Input Commands
Commands sent to the analyzer from a computer must be formatted as an ASCII character
string in uppercase or lowercase letters. Spaces are allowed, but not required. All
commands start with a three character string. If additional information is needed to set a
value, an equal sign “=” is entered, followed by the data desired. The command is
completed by sending a CR (OD Hex) [Example: To recall the alarm 1 setpoint:
A1S<CR>; to set alarm1 setpoint to 7.5: A1S=7.5<CR>]. Refer to Table 6 for a complete
command list.
All commands except cold start (CST) generate a response message indicating acceptance
or rejection of the command from the analyzer. If the command is rejected, the response
is “[?.”
Response messages from the instrument are preceded by a steering character, which the
computer program can test to determine if the line is a response message or if the line is a
routine printout. The steering character is an ASCII left bracket “[”(5B Hex).
Note: If the print interval is
set to zero (disabled), then
the only outputs generated
are response messages.
Programs (Basic, C, etc.) must be written for the computer to transmit the proper
command strings to the analyzer via the interface.
