Unihedron SQM-LU Users manual
3 Hardware connections
The SQM-LU requires one connection to a USB hub or a PC.
The maximum length cable per the USB specification is 15ft (3 meters).
2 Software development
The SQM-LU communicates as a standard serial port device using the FTDI software drivers which are
available for all major operating system platforms.
http://ftdichip.com/ . The SQM-LU uses the FTDI
FT232R chip.
Once the driver is installed, commands can be sent to the SQM-LU using a serial terminal emulator to
the serial communications port that the device routes to.
When connecting the SQM-LU to a PC where the FTDI device driver is loaded, the serial port label
will be determined at connection time.
Each SQM-LU has a unique serial number usually with a prefix of “FT........”. This serial number can
be used to identify the exact SQM-LU device from other USB devices.
Interface Program overview:
–
Data commands are sent to the SQM-LU, and it responds with a string of characters.
–
A connection must be made to the serial port assigned to the SQM-LU.
