GSIOC Commands
GSIOC Commands
There are two kinds of commands that you can
send over the GSIOC:
• Buffered commands send instructions to the
liquid handler. These commands are executed
one at a time.
• Immediate commands request status
information from the Quad-Z 215. These
commands are executed immediately,
temporarily interrupting other commands in
progress.
GSIOC Command List
In the command list on the following pages, the
GSIOC command must be entered in the proper
upper or lower case format. If a buffered command
requires additional information, you’ll see italicized
text next to the command. The description of the
command identifies what you need to enter in place
of the italicized parameter. Also note that if a
parameter is optional, it appears within brackets, [ ].
I - Immediate
B - Buffered

% I Identifies the selected slave device. Returns character
string: “215QADVx.yz”, where x, y, and z represent
