Hardware issue with PCI 2 COM PORTS with 633


New member
Hi all,
First thing, 633 is a very,very , very good product.
I encountered an issue while trying to plug the 633 Serial LCD on a PCI card with two com ports.
The panel seems to work fine (Light on and splash screen visible), but no way to add screens with crystal control nor 633wintest software.
Well, i've tried it after with annother computer equiped with onboard serial ports and all worked fine....
Have an idea ?

Thx for all....

Sounds like you just didnt configure the COM port properly.

Go into the windows device manager and make sure that the PCI com port card is setup correctly, and there are no conflicts, etc.
