For the PM101U and PM101A power meters, instrument control and power supply are facilita- ted via the USB port. The PM101R can be controlled via the DE-9 port. The PM101 can alter- natively use the DA-15 interface for instrument control and to connect a power supply. For...
Thorlabs offers a variety of SMA connector cables. · PM101: Cable to attach to the provided DA-15 connector housing. Mounting · Horizontal Mounting Clamp (ECM225) to mount the PM101x onto a post. · Vertical Mounting Clamp (ECM100) to mount the narrow side of the PM101x onto a post.
PM101A: Please provide an appropriate cable to connect to the SMA port. Software Requirements All models of the PM101x can be run with the Thorlabs' OPM software. Please see the require- ments for the OPM on the website. Sensor Requirements Thorlabs C-Series Sensors The PM101x supports all Thorlabs C-Series photodiode and thermal sensors.

· 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.

DE-9 connectors. Note Custom Sensors To use sensors without a DE-9 connector, manufactured by Thorlabs or else, the user may provide an appropriate adapter. To build the adapter, refer to the Pin-out of the DE-9 connector shown in the Appendix .
The PM101 features a number of additional options, due to the DA-15 output connector. The PM101 is per default configured to RS232 configuration (+/- 5 V voltage level). This can be changed to a UART configuration (0/5 V voltage level) so that the PM101 can be accessed by external micro-controllers for instrument control and data export.
Termination Character LF (x0A; \n). The termination character needs to be enabled. Note PM101: To operate the PM101 via RS232, RxD, TxD, and GND need to be wired from the DA-15 con- nector to a 9 Pin female connector to perform the connections. PM101 DA-15 Pin...
PM101 control. In RS232 operation the PM101 uses voltage levels of +/-5 V, while in UART mode the voltage level is shifted to 0/5 V. The PM101 can also be adjusted to accommodate micro-controllers using 3.3 V. When switched to 3.3 V, UART operation is toler- ant for 5 V input signal.
Power meters PM101 and PM101A can be run autonomously by only connecting a power sup- ply and using analog output. In that case, no control device is required. For the PM101, both analog output ports can be used for autonomous operation.
PM101x 3.2.15 NTC Input To monitor the temperature in a test environment, the PM101 has an NTC Input (DA-15 Pin 14) which allows connection of an NTC thermistor. The measurement range is 0.1 – 100 kW. The set range R0 and the bandwidth B for the NTC thermistor can be adjusted in the OPM software or through SCPI commands.
NTC measurements results in long-time monitoring experiments. For more information, please see the OPM manual. 2. When a PM101 is connected, it is possible to configure the analog AO2 port and display the output voltage. 3.3.2.2 PM101A Specific Software Functions When a PM101A is connected, it is possible to configure the analog SMA port and display the output voltage.
Not Connected N.C. Not Connected N.C. Not Connected PM101: PM101 has a universal DA-15 connector. The Pins are assigned as follows: Pin Function Description Power Supply Pin for Alternative Power Supply with 5 VDC to 36 VDC I/O 1 General Digital Input / Output port; 3 V logic (Output), 5 V tolerant for In- I/O 2 General Digital Input / Output port;...
Warning Pin 2 is uniquely used for the EEPROM Digital I/O (memory in Thorlabs sensor heads) and MUST NOT be used. Connecting this Pin may cause malfunction of the PM101x. Pin-out of the DE-9 female...
