Switching between USB and RS-232 and Keyboard Output Mode
On the GageMux® USB you have an option to use either the USB or RS-
232 port for communication.

switches, make sure Jumper J5/6 is removed. Once the jumper is
removed, set switch 1 for the desired output. Hit the reset button to
activate the new setting.

Switching between RS-232 and USB using E-Commands:
If you are plan to switch between USB and RS-232 using the E-
Commands, make sure Jumper J5 is placed between pin 5 and pin 6.
Once the jumper is installed, set the GageMux to the appropriate
output mode based on the E-command table. Hit the reset button to
activate the new setting.

USB Keyboard Output Mode Option:
If the keyboard option board is installed and the USB Keyboard
enabled, the keyboard output mode can be set by either using rotary
switches or E-commands. Use the rotary switch table and E-
commands table to set the mode. By default, the standard GageMux
USB with keyboard option is set with keyboard output mode followed
by a carriage return <CR>.
Output String Format
The GageMux® USB can be configured for three different output string
formats. Those readings are: Reading only, Full Comma-Delimited, and
Mitutoyo Mux-10 format.

SRRRRRRR<CR><LF>
Where S is a space and
RRRRRRR
is the reading. It is followed by a
carriage return and line feed. For example, a gage with an output of -
