9. Commands
9.1. Interface
The MEX can be controlled using either USB 2.0 or
RS-232 interface. The device will switch to the required
interface upon connection of the appropriate cable.
When using the RS-232 interface, MEX communicates on
the
configured Baud rate (by default 57600) (see
Command descriptions), using 8 data bits, no parity and
1 stop bit .
When the device is connected to the PC through the USB
interface, it will appear as a
Virtual Serial COM port , so
all PC side communications are interchangeable between
the two interfaces.
All communications with MEX are conducted by sending
literal ASCII string commands terminated with the
newline character \n
. For example, the beam expansion
coefficient can be set to 2.5 by issuing a “ MEX>MAG!
_2.5\n ” command to which the device will respond with
“ MEX>MAG_2.5\n ”.

Motion |
Magnification - MAG, Magnification o ff set - MOF, Divergence o ff set - DOF
MEX>MAG? MEX>MAG_X.XXX
Command used to get the current
magnification value from the device.
MEX>MAG? MEX>MAG_1.250
MEX>MAG!_X.XXX MEX>MAG_X.XXX
Command used to set a new magnification
values.
MEX>MAG!_2 MEX>MAG_2.000
MEX>MAG!_2.5 MEX>MAG_2.500
MEX>MAG!_2.547 MEX>MAG_2.547
MEX>MOF? MEX>MOF_X.XXX
Command used to get current magnification
adjustment coefficient (0 - means the lenses
in the device is in their theoretical positions)
MEX>MOF? MEX>MOF_0.3
MEX>MOF!_X.XXX MEX>MOF_X.XXX
Command used to adjust magnification
values:
+ to increase magnification
- to decrease magnification
(For. Ex. 1X magnification value (MAG_1) is
chosen, but according to your laser beam
parameters 1.09X actual magnification value
is reached, so to calibrate magnification to
required value MEX>MOF_-0.7 command
must be sent)
MEX>MOF!_-0.7 MEX>MOF_-0.7
MEX>DOF? MEX>DOF_X.XXX
Command used to get current divergence
adjustment coefficient (0 - means the lenses
in the device is in their theoretical positions)
MEX>DOF? MEX>DOF_1.6
