PC Connection Mode (OPTIONAL)
As an optional feature, the DFB-4-B unit is capable connecting to an external PC to
allow for parameter monitoring and laser diode adjustments. If you have a DFB-4-B
unit with additional software control, please refer to the following below for the software
connection option.
1. Using the USB port on the rear panel, connect the DFB-4-B to a PC, directly to the
USB port with an appropriate USB to USB cable.
2. By using the Device Manager (or other similar PC device tool), the DFB-4-B should
be recognized as COM Port device. If the DFB-4-B does not appear as a COM
Port device, you may need to install the necessary RS232 drivers included on the
software package.
3. A command set for the DFB-4-B unit can be found in section 5 of this manual.
Please refer to this command set if using an RS232 communication tool such as
termite or similar.
4. A LabVIEW executable is also available for communicating with the DFB-4-B unit.
If applicable, refer to the DFB-4-B software DVD and run the setup.exe file in the
installer folder. This executable will install the appropriate run-time engines and/or
support files as well as the DFB-4-B LabVIEW program and a shortcut will be
created on the desktop for all users.
