3.1 How To
This chapter describes how to install the PM101x for standard measurements.
3.1.1 PM101x Setup
·
Download and install the
software on the device that will be used to
control the power meter interface (PC, laptop or tablet).
Note
Install the software prior to connecting the power meter interface to the PC (see
).
·
Connect the PM101x to a PC or other power source via the USB port.
o
The PM101 accepts external power supplies with 5 V to 36 V via the DA-15 interface.
When connecting the USB port while using an external power supply via the DA-15
port, connecting the USB port will automatically switch to the 5 V power supply via
USB.
o
The status LED for the power supply is yellow in USB mode and green when connected
to an external power supply via the DA-15 connector.
·
Connect the PM101x to a readout instrument (PC) using the USB cable or a matching
cable for the respective output port (DE-9, SMA or DA-15). For PM101A and PM101,
please provide cables.
·
to the PM101x.
The sensor status LED indicates, when a sensor has been detected (green) or when no
sensor or no recognizable sensor is connected (red).
The Power Meter is now ready for operation and is recognized by the OPM software.
Note
For detailed instructions on controlling the PM101x through the OPM software, please down-
load the OPM
3.1.2 Connecting a Power Sensor
The PM101x supports all Thorlabs C-Series photodiode and thermal sensors, that can be iden-
tified by the red connector-housing of the DE-9 connector, compared to older versions of
Thorlabs power sensors. Sensor type and calibration data are saved in the non-volatile memory
of the DE-9 connector. Upon connection, this information is automatically sent to the PM101x
and to the control device and software. The software will automatically recognize the sensor.
To plug-in or remove a sensor, slightly press on the two bolts in the connector housing, that fix
it by tension.
