Power and Environmental Requirements
PHOTON+System Guide 9
3 Power and Environmental
Requirements
Power Requirements
Power for the PHOTON+is provided by the USB connection. No other
power connection is needed. The USB standard requires the USB port to
provide 2.5 Watts of power to the USB device. The PHOTON+can
consume as much as to 2.5 Watts. To ensure proper power supply to the
PHOTON+, it is not recommended that it be used on a hub with other USB
devices.
2.5 watts at 5 volt DC is equivalent to 500mA of electrical current. Some
PC USB-controllers provide the electrical current information. Below is
a bitmap showing the power management of the USB Root Hub with a
LDS-Dactron PHOTON+under typical operation:

Power and Environmental Requirements
PHOTON+System Guide 10
USB Cable Requirements
The maximum USB cable length is 16 feet. Additional USB cables can
be added to increase the length provided that a powered USB hub is
added between cables to boost the power.
Environmental Requirements
Operation
When powered on, the allowable ambient temperature for operation of
the PHOTON+is from 5 to 45 oC (41 to 113 oF). The relative humidity
range for operation is from 10 to 90% under non-condensing conditions.
Storage and Shipment
Store the PHOTON+in a clean, dry environment. The following
environment limitations apply to both storage and shipment:
Temperature: -20 to 60 oC (-4 to 140 oF)
Humidity: Up to 95%
The system should be protected against temperature extremes that would
cause condensation within the system.
Packaging for Shipment
Original Packaging
Use the original factory packaging containers to return ship the system to
LDS-Dactron for Calibration or service. If the system is being returned
to LDS-Dactron for service, attach a tag indicating the return
merchandise authorization (RMA) number provided by LDS-Dactron
customer support, type of service required, return address, system model
name, and serial number.
The following general instructions should be used for repackaging with
commercially available materials:
1. Wrap the system with heavy paper or plastic.
2. Use a strong shipping container. A double wall carton made of 350-
pound test material is adequate.

Power and Environmental Requirements
PHOTON+System Guide 11
3. Use a layer of shock absorbing material 3 to 4 inches (70 to 100 mm)
thick around all sides of the system to provide firm cushioning and
prevent movement inside of the container. Protect the control panel
with cardboard.
Caution
Styrene pellets in any shape should never be used as packing
material. The pellets do not adequately cushion or prevent the
system from shifting in the carton. The pellets also create static
electricity that can damage electronic components.
4. Seal the shipping container securely.
5. Mark the shipping container FRAGILE to ensure careful handling.
6. In any correspondence, refer to the system by model name and serial
number.

System Installation
PHOTON+System Guide 12
4 System Installation
Step 1: PHOTON+Driver Installation Instructions
The PHOTON+communicates with the PC through a USB
connection. This requires Windows driver software to enable the
USB connection. The USB is a “plug and play” device which
means that after the driver is initially installed, the configuration
of the driver is automatically launched every time the device is
plugged into the USB port. To install the PHOTON+driver you
will need the PHOTON+hardware, a USB cable, and the
installation CD.
The driver installation process first locates the INF file named
Photon.inf on the CDROM. Using the information provided by
Photon.inf, the device driver file Photon.sys is copied into the
Windows\ System32 \drivers folder. The operating system
registers the PHOTON+device in its registry so the next time the
PHOTON+is plugged in it can be identified. Finally the
Photon.inf file is copied into the Windows\INF or its subfolder
for future use.
Follow the instructions below to install the PHOTON+driver
software.
1. Turn on the PC and launch Windows. Your PC must use a
Windows Vista or XP operating system. If you are using
Windows Vista you must be logged on with administrator
privileges to install a new driver.
2. Place the Install CD into the CD drive.

System Installation
PHOTON+System Guide 13
3. Plug the USB cable into the PHOTON+and the PC.
The PC will auto detect the presence of the new hardware and
launch the “Add New Hardware Wizard.” Note the dialog boxes
shown below are from Windows XP. The dialogs for Windows
Vista will vary slightly.
3. Select “Install the software automatically (Recommended)”
4. Click on the Next button.
5. Once the Photon USB driver is located, it will automatically
install

System Installation
PHOTON+System Guide 14
6. If the files are not automatically located, they are named
Photon.sys and Photon.inf and are in the root directory of the
installation CD ROM.
7. Select, “Continue Anyway” when the Windows Logo Testing
message appears.

System Installation
PHOTON+System Guide 15
The driver installation should now be complete. Press “Finish”
The driver is now installed and the PHOTON+should be auto-
detected every time it is plugged into the USB cable on this USB
port. If a different USB port on the same PC is used, the driver
will need to also be installed again for this second USB port.
Step 2: Installing Application Software on the PC
Application software, such as the RT Pro Dynamic Signal
Analysis Series, is installed on the host PC. Refer to the “RT
Pro Dynamic Signal Analysis Series” User Guide, “Installation
and Setup Procedure”, for complete details on installation of
application software.
The PHOTON+is now ready to run. Start the LDS-Dactron
application software from the host PC then you will be ready to
use the application software.
Step 3: Running the RT Pro Software
When the PHOTON+is combined with RT Pro Dynamic Signal
Analysis Software, the result is a full featured dynamic signal
analyzer.
1. If your PHOTON+is not already connected to the PC’s USB
connector, please do so now. Then, start the application
software by either double-clicking on the RT Pro icon on the
Windows desktop, or by selecting RT Pro from the Windows
Start menu.

PHOTON+System Guide 16
2. The next screen that appears is the hardware initialization
screen, which shows the progress of the system firmware
download into the PHOTON+’s Digital Signal Processor.
3. Once the DSP code downloading is finished, the calibration
file import prompt will appear.
4. Insert the Calibration CD that came with your PHOTON+
system into the PC. This CD contains the calibration file that
was generated for your PHOTON+prior to shipment. You
must load this file in order to have a calibrated and accurate
PHOTON+. After placing the calibration diskette in your CD
drive, select “Yes” to import the calibration file.
5. Your PHOTON+system is now calibrated. You will next see
