3.4. Custom Application Development
One option for users interested in developing custom software is to use our Remote Control application as a
reference and starting point. Please contact us to request the source code. Using this source code and a
development platform such as free version of the Qt
®
software, our example application can be modified and
expanded.
When the computer is connected to the RS-232 port on the MX / MBX / TLX1/ TLX2 series instrument,
commands are sent directly to the instrument’s universal asynchronous receiver/transmitter (UART). This is not
the case for applications communicating with the instrument over USB. In this case, commands sent by the
computer address a Silicon Labs
®
USB to UART bridge chip built into the instrument. The UART is interfaced to
the bridge chip. A dynamic-link library (DLL) available from Silicon Labs’ website can be used to communicate
with the bridge chip.
If you have questions or would like guidance as you develop a custom test configuration, please contact us. We
are happy to assist you.
