Go to the port configuration settings and replace the standard 0x378 address with your card's specific address (e.g., 0xD000 ). 5. Troubleshooting Common Issues Issue 1: "Device Cannot Start (Code 10)"
The CH351Q is a PCI bus bridge chip. It's the "brain" found on the majority of PCI-to-Parallel port expansion cards available on the market. Its primary function is to connect your computer's PCI bus to a standard DB25 parallel port connector, allowing you to use legacy parallel devices.
The card is not seated properly, or the motherboard BIOS is disabling legacy port routing.
If you are using the CH351Q for CNC (like Mach3, EMC/LinuxCNC) or a logic analyzer, latency is critical.
These steps are the same for all modern supported Windows systems (10/11, 8, 7, Vista, XP), including Server editions.
Long cables or poor shielding can cause signal degradation when routing data through a PCI bridge chip.
Always use the official WCH drivers to ensure stability and security. Visit the official WCH website (wch-ic.com).
: Run SETUP.EXE within the extracted folder. Windows should automatically detect the "PCI Parallel Port" or "PCI Serial Port" after a reboot. ⚠️ Common Troubleshooting Tips
