No Communications between Panel and PC (Personal Computer) (cont’d)
3. Not using the correct COM port assigned to the USB adapter - If the C-more Micro-Graphic
panel is on the setup screen and the cable
connection is correct, then check the PC COM
port setting.
If you are unsure which COM port the C-more
Micro-Graphic programming cable is connected
to, click on the
Device Manager button. This
will open Windows ® Device Manager .
In the Device Manager window, view the active
ports by clicking the + button beside the Ports
(COM & LPT) menu item. The
C-more Micro-
Graphic panel uses a USB driver called Koyo
USB-Serial Comm Port .
COM4 is the USB port used in this example. If you
cannot find the Koyo USB-Serial Comm Port under
Ports (COM & LBT) in
Device Manager , the USB
driver may not be correctly installed or the driver has
a problem. Disconnect the cable from the PC and
follow these steps to re-install the driver:
• Uninstall the C-more Micro-Graphic programming
software.
• Unplug the cable between the PC and the C-more
Micro-Graphic panel.
• Re-install the C-more Micro-Graphic programming
software. Make sure the install USB driver checkbox
is selected.
If you have selected the correct COM port and the
error still occurs, try connecting the programming
cable to a different USB port on the PC and try again.
If the problem persists, call Technical Support at
