Remote Control Features

The TLX3 provides two communication methods for remote control, USB and RS-232. Note that a custom
Windows driver is required for programming via the USB interface. This driver is installed automatically with the
GUI software package included with the TLX3.
Both the RS-232 and the USB connections can be used for remotely controlling the TLX3 laser via SCPI type serial
commands. Which connector to choose for remote control operation depends on the demands of the application and
the user's preference. See the Programming Guide for information about the commands and connecting the laser to
a PC. (https://www.thorlabs.com/manuals)

Boot Mode Indicator
In normal operation mode, the indicator LED will glow a steady green color. The recessed "Boot Mode" button is
never used in normal operation. It is not a "RESET" button. It is used to place the instrument into special modes to
allow installation of firmware updates.
Documentation explaining how to use these modes will be included with any future firmware update files, which will
be made available as needed on the Thorlabs web site. Please contact Thorlabs technical support if you have any
questions.
