FTDI COM Port Trouble-Shooting
CLI measurement can be displayed in two different formats: decimal or hex. Both formats are returned as
ASCII character strings. The following figure uses CLI commands to return the same data presented in
the Auto-Reporting mode.
Refer to the applicable Firmware Description Document for a complete description of available CLI
commands and their invocation usage.
If the FTDI device driver did not install properly, there would be no assigned COM port
number for the FTDI controller. Repeat the USB Driver Installation, see Section 2.1.
Microsoft Windows may associate a Ball Point device to the FTDI USB controller. When this
occurs a FTDI device COM port assignment is available via HyperTerminal but there is no
communications data. Verify if a Ball Point device has been added to the “Human Interface
Devices” via the Device manager. Refer to Section 2.2 for access to the Device Manager. If
a Ball Point device exists, delete it and unplug and replug the evaluation board’s USB cable.
Use “?” for Decimal format
Use “$” for Hex format
