When I connect my PC to P143 Relay, it is showing a message that DDB is invalid. Sometimes the connection is OK, but PSL logic is not complete. What can I do?
In order to fix the problems, I recommend you update the drivers of the P143 device. For this purpose, you will need to contact the device manufacturer and ask for the updating package. You can get in touch with Alstom using the Contact Us page.
