PM103x Optical Power Meter Interfaces Chapter 2 General Information
Chapter 2 General Information
The PM103x Optical Power and Energy Meter interfaces measure the optical power of laser light or
other monochromatic or near monochromatic light detected by a connected sensor. Their high
repetition rate up to 80 kHz supports even fast pyroelectric sensors. The PM103x power meter
interfaces are compatible with all Thorlabs “C-Series” Photodiodes, Pyroelectric sensors, and
respective custom sensors.
To flexibly integrate the PM103x into a setup, the PM103x models offer different electronic
interfaces for instrument control and output:
·PM103: USB port, Dual I/O port, and DA-15connector
·PM103A: USB port and SMA analog interface (Output only)
·PM103U: USB port only
·PM103E: Ethernet Port, Phoenix DMC Connector, Dual I/O port
The USB port features a fixture for secure connection of the cable to the housing.
For the PM103U and PM103A power meters, instrument control, and power supply are facilitated via
the USB port. The PM103 can alternatively use the DA-15 interface for instrument control and to
connect a power supply. Furthermore, the PM103 can be controlled via an external micro-controller,
supplied by the customer.
The PM103E can use the ethernet cable for power supply, if the network supplies Power over Ethernet
(PoE). Alternatively the PM103E can be powered via its Phoenix DMC Connector. For more information
on the special features of the PM103x models, please see the table PM103x Model Comparison
below.
For instrument control and data analysis through a connected PC, tablet or laptop, Thorlabs offers the
Optical Power Monitor (OPM) software. Instead of the OPMsoftware, the user can write custom made
software. For this, information on driver and SCPI commands are provided in the manual
WriteYourOwnApplication (WYOA) for the PM103x.
In summary, the PM103x models give the customer the choice of different interfaces, provide a
supplied control and analysis software, and have the option to use custom made software. These
features allow for maximum flexibility to integrate the instrument in test and measurement systems
and a wide range of industrial and scientific applications in manufacturing, quality control, quality
assurance, and R&Dfor stationary and field use.
The PM103x offers the customer to implement a large number of powermeters parallel and at the same
time into their application.

Page 12 MTN023788_D02
PM103x Optical Power Meter Interfaces Chapter 4 Operating Instructions
In case a USB communication is established in addition to the DA-15 connection, the PM103 switches to
USB-Mode and the DA-15 serial interface becomes inactive. Only after actively closing the USB
connection, the serial communication is reestablished.
When switching the PM103 in the opposite direction, from USB to RS232 operation or to UART
operation, PM103uses the DA-15interface for control and output.
4.2.2.5 UART Operation
The PM103is delivered in RS232operation but can be switched to UART operation.
UARTdependent PM103 functions:
The PM103 may need to be switched from RS232 to UART operation when using an external micro
controller for PM103control. In RS232 operation the PM103 uses voltage levels of +/-5 V, while in UART
mode the voltage level is shifted to 0/5 V. The PM103 can also be adjusted to accommodate micro-
controllers using 3.3 V. When switched to 3.3 V, UART operation is tolerant for 5 V input signal.
For instructions on how to change the voltage level for UART operation, please refer to the document
Write-Your-Own-Applications (WYOA) for PM103x.
For UART operation, please use standard protocols for UART communication and the SCPI commands
listed in WYOA for PM103x.

Note
After adjusting the Baud Rate via RS232 or UART, close the RS232 or UART connection and reconnect
with the desired Baud Rate in order for the Baud Rate to communicate it via RS232/UART. This is not
required for operation via USB.
4.2.2.9 Non-Volatile Memory
All PM103x models have an internal non-volatile memory for all settings (i.e. wavelength setting,
ranging, analog output configuration). The PM103x will start in the same configuration as prior to shut-
down.
4.2.2.10 Digital I/O Ports
PM103
The PM103 has two configurable gerneral purpose digital ports, DIO1 (DA-15 Pin2 ) and DIO2 (DA-15
Pin3 ). Both ports can be configured as digital input or output and queried per remote control
command. These digital I/O ports use 3 V logic for output and are tolerant for 5V input signal.
DIO1 can additionally be configured as trigger in and output, when reading the data in the 100 kS/s
mode. The trigger function is supported by the Optical Power Monitor software. Alternatively, the DIO1

PM103x Optical Power Meter Interfaces Chapter 4 Operating Instructions
4.2.2.11 Analog Output
PM103
The PM103has two analog outputs, AO1and AO2(please see Pin assignment ).
The Analog Output ports provide the amplified photo-diode current or the pyroelectic sensor voltage,
depending on the sensor. The signal from the analog output AO1is not wavelength- or zero- corrected.
The signal is measurement range dependent and can be calculated to:
AO1: The AO1 (DA-15 Pin 4) delivers the amplified direct real analog signal without a Digital-Analog-
Converter (DAC). Therefore, the AO1 delivers a proportional output voltage for each measurement
range. This analog output voltage can range from -0.25 V to +2.5 V. The real analog signal is not
wavelength- or zero- corrected and offers the full bandwidth (up to 1 MHz) without quantization error.
Note
The bandwidth is in accordance with the settings of the sensor and power meter.
AO2: The AO2(DA-15Pin 5) delivers a range independent voltage which is DAC controlled. The output
voltage is proportional to a configured value in V/W or V/J. This constant can be adjusted via the OPM
software or, for custom made software, using the SCPI/driver commands in the WYOA for PM103x. The
constant can be set in the Thorlabs software OPM under the Settings tab: AO2 Responsivity. The signal
of the AO2is generated with a 16-bit DAC with an update rate of 1 kHz. The analog output voltage can
range from -0V to +2.5V.
The analog signal following the DAC is of advantage when large signal dynamics are expected because
the DAC range changes and the output signal stays largely the same. Additionally, the output signal is
wavelength corrected and corrected regarding the sensor calibration data.
PM103A
The PM103A has two analog output ports with a SMA output connectors. The functions match the
function of AO1and AO2 of the PM103 respectively.
4.2.2.12 Autonomous Operation to Analog Output
Power meters PM103 and PM103A can be run autonomously by simply connecting a power supply and
using one of the analog output ports . In that case, no control device is required.
4.2.2.13 NTC Input
To monitor the temperature in a test environment, the PM103 has an NTC Input (DA-15, Pin 14) which
allows connection of an NTC thermistor. To connect the ground of the TSP-TH, please use one of the
GND connectors DA-15 Pin 10 through Pin13. 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. The default settings are 10 kWand 3988K to directly access the TSP-TH temperature probe.
The measurement range with the PM103is then -10 °C to 80°C with the TSP-TH.

PM103x Optical Power Meter Interfaces Chapter 4 Operating Instructions
4.2.3.1.1 Introduction and Prerequisites
Ethernet is the universal communications protocol commonly used for building Local and Wide Area
Networks (LAN & WLAN). Over 40 years ago commercially introduced, this connectivity technology is
still the most widely adopted.
With well-established industry standards, the configuration and adaptation of Ethernet is made easy.
There are supported different technologies to establish point-to-point, hub & spoke, or any-to-any
connections.
Note Important Terms:
OSI and TCP/IP
The OSI (Open System Interconnection) model is a conceptual layer model that characterizes and
standardizes how various software and hardware components involved in a network communication
should divide the work and interact with each other.
TCP/IP is also a layered model, but also describes the commonly used data transfer protocol. In fact, it
is a set of protocols. TCP/IP stands for Transmission Control Protocol and Internet Protocol.
LAN
The abbreviation LAN stands for Local Area Network and describes a network, that is limited to a local
area in terms of its spatial extent.
WLAN
The term WLAN is the abbreviation for Wireless Local Area Network
VPN
A Virtual Private Network (VPN) is a network that imitates a private network using a public one. Thanks
to the VPN connection, it is guaranteed that your internet traffic, including your IP address, remains
encrypted.
IP address. An IP address is an address in computer networks which – like the internet – are based on
the internet protocol. It is assigned to devices that are connected to the network, making the devices
addressable and therefore accessible.
Port
A port is the part of a network address that causes operating systems to assign TCP connections and
data packets to server and client programs. Ports are primarily a feature used to distinguish multiple
connections between the same pair of endpoints.
Thorlabs devices use the standardized TCP port number 80 for http protocols, the registered ports 2000
for SCPI command-based communication with the instrument, and 27007for firmware updates.
Subnet-mask
In computer networks, the subnet mask or network mask, in conjunction with the IP address,
determines which IP addresses a device in its own network can reach without the aid of a router
Hostname
The hostname is the unique name of a device within a network.
MAC address
The MAC (Media Access Control) address is the number of a device on a data connection. This number is
used to assign data running over the connection to the devices. The MAC address is the hardware
address of each individual network adapter, which serves as a unique identifier for the device in a
computer network.
DHCP
DHCP stands for Dynamic Host Configuration Protocol. It is a standardized
