Troubleshooting
If this message box appears immediately after launching the ARP GUI, select OK and proceed to the following steps:
Figure 15. Unspecified Error Window
1. In Project menu, under Options -> Comm tab, select correct COM port associated with the FTDI cable now connected to the host
computer. Speed used for this GUI is 256000.
2. Open "File\Start communication" to establish the connection.
Incomplete and/or inaccurate execution of the above steps results in the message depicted in
Figure 15
.
The error sources could be:
•
The ARP demo has no power. Check the power supply setup.
•
COM ports are not assigned correctly.
•
On the PC desktop, right click on "My computer" and select "Properties". The "System Properties" window will open.
•
Select the "Hardware" tab, then select the "Device Manager" button. In a new window, expand the "Ports (COM & LPT)".
•
If the USB drivers are installed properly, the virtual COM ports will be listed, e.g. "USB Serial Port (COMx)". The PC
assigns COMx port number. Note the port number used for FreeMASTER control pages configuration described in
Step 1
above.
COM ports are now assigned correctly, and the previous message box no longer appears. Instead, at the bottom of the GUI, a message
“Communication With Reference Board Works Properly” is seen. See
Figure 16
