2.4.1.3 Serial Commands
The Serial Commands Menu allows you to configure the serial communication and input/output port
settings. Refer to section 3.4.3 for the complete serial commands directory. All the settings in this menu
are automatically saved, which means that at each reboot, the last changed settings will be loaded.
In order to ease the integration of the MAESTRO with setups using our legacy monitors, select SOLO2
Serial Compatibility. Note that only the ASCII commands are available. This feature is only available
when using the USB port for serial communication. Refer to section 3.4.4 for more information about the
available SOLO2 commands.
For fast data acquisition in energy mode, select Serial Binary Measurement. Refer to section 3.4.2 for
more information on how to use the MAESTRO’s serial binary measurement mode.
The serial communication can be done via USB port or RS-232 port. To use the RS-232 port, you must
use the special cable (part number 201860). Before using the serial communication after it was changed,
you must reboot the MAESTRO.
To use the analog output using the special cable (part number 201958), select Analog Output. The
MAESTRO will not need to be rebooted. This output allows the monitoring of the laser
’s average power or
energy with external equipment such as a chart recorder, a computer with an analog interface, a
voltmeter, etc. In the case of a power measurement, the output signal represents the amplified and
anticipated power detector response. In the case of an energy measurement, the output signal is a DC
voltage representing the pulse energy value. In order to improve the signal to noise ratio, the 1 volt value
corresponds to the full scale reading of the selected range. The measured power or energy is then
related to the output voltage and to the selected range according to the following equations:
