Full Comma-Delimited Format
In the full comma-delimited format, the output string will look
like this:
NNN,SRRRRRRRRR,SMMM,SCC<CR><LF>
+++++++++++++++++++++++
00000000011111111112222
12345678901234567890123
Where
NNN
is the reading number,
RRRRRRRRR
is the reading,
MMM
is the mode, (MIN, MAX, TIR, NRM),
S
is a space and
CC
is the channel number. It is followed by a carriage return and line
feed. As an example, two consecutive readings from a gage with
an output of –1.234mm plugged into Port 1 running in normal
mode would look like:
001, -1.2340, NRM, 01
002, -1.2340, NRM, 01
+++++++++++++++++++++++

Foot Switch Operation
Described below are the modes of operation for the foot switch, Normal
Foot Switch mode, Global Foot Switch mode, and Foot Switch Triggered
mode.
•
Normal Foot Switch Mode
Each input is controlled by it’s own foot switch or gage send
button.
•
Global Foot Switch Mode
In global foot switch mode, any time a foot switch or gage send
button is activated, all available GageMux
®
inputs will be scanned
for a reading. When multiple GageMux
®
units are dais y chained
together, each GageMux
®
must be set in this mode for the port
scanning to operate correctly.
•
Foot Switch Triggered Mode
In this mode, any time a foot switch or gage send button is
activated, the GageMux
®
does not send a data string. Instead,
“
F<CR>
” (the letter f followed by a carriage return) is sent. This
mode is most likely used when the GageMux
®
is under software
application control. The GageMux
®
is still capable of sending
data using host commands through the serial port. If an operator
accidentally presses the foot switch, the application software will
be aware that the foot switch was pressed but will not record a
reading.
