SERIAL DATA OUTPUT
These Testing Machine Inc. Micrometers (Thickness Gauges) output a string through a mini-USB
connector on the back panel of the instrument.
The USB host (PC) will need to be looking for serial data on one of its COM ports. The number of the
COM port will vary from host to host.
These are the settings needed to capture the serial data -
Baud rate: 9600
Data: 8 bits
Parity: None
Stop Bit(s): 1
Flow Control: None
Here are some serial string examples-
x
Initial string - "CC5.1.1.13;"
o
This is an identifier string used by our GraphMaster product. You can ignore it if you are
not using GraphMaster. It will only show up after powering on.
x
After each cessation of downward motion, like the spindle coming to rest on a sample, the
machine will output a serial data string in the following format.
TM V00.01.02 49-87-00-000112345-67 0000000004.370
