
Single Triggered Foot Switch Mode
Single trigger foot switch allows an operator to use one footswitch
to trigger each gage reading sequentially. If the device or gage has
a send button, and data is sent from the gage using the data send
button, the GageMux® will see the data sent from the gage send
button and move to the next gage in the sequence.

Armed Foot Switch Mode – Host Commands
Only the specified port in the data request is armed and can have
data requested from it. A solid green LED displays the specified
port. When a foot switch plugged into port 1 is closed (pressed),
the channel specified in the host command will be triggered and
the data requested. After the data is sent none of the channels are
armed and no data can be requested until another command is
received from the host computer. When multiple GageMux®
units are daisy chained together, the footswitch in port 1 is used to
request data from specified channel even if the channel is on
different GageMux® box.

Global Foot Switch Mode
In global foot switch mode, any time a foot switch or gage send
button is activated, all available GageMux® USB inputs will be
scanned for a reading. When multiple GageMux® USB units are
daisy-chained together, set all the backplane units to RS-232 as
the output mode and to global footswitch mode
