The is a widely utilized legacy hardware printed circuit board (PCB) identifier found on specific multiport extension cards manufactured by Delock . These expansion cards insert directly into a computer’s computer motherboard via a PCI Express (PCIe) x1 slot . They are designed to add legacy physical ports—such as RS-232 Serial (DB9) communication channels or IEEE 1284 Parallel (DB25) printer lines —to modern computers lacking native old-school standard outputs.
Look down the list for an item marked with a yellow exclamation point, typically labeled or "Unknown Device" . Right-click the unconfigured node and select Update driver . Step 4: Map the Directory Target
Because the PI40952 uses logic inputs, you can implement speed control by enabling/disabling the channel rapidly using PWM on the EN pin OR by toggling one of the input bits. The cleaner method is using the enable pin: pi40952 3x2b driver
: Some later revisions or similar multiport cards use WCH (Nanjing Qinheng) chips like the CH382. If the Oxford driver doesn’t stick, try the CH38XDRV package from the manufacturer's site. Why Bother in 2026? Why are we still talking about serial ports?
Most modern drivers for this hardware support a wide range of Windows environments: (32 and 64-bit) Windows 8.1 / 8 Windows 7 Windows Server (2012, 2016, 2019, 2022) Installation Steps The is a widely utilized legacy hardware printed
Works with Windows versions from XP/7 up to Windows 11 .
To effectively integrate the PI40952 into a design, one must master its pin functions. The "3x2B" arrangement typically organizes pins as follows: Look down the list for an item marked
Legacy communication interfaces remain vital for industrial, medical, and specialized retail workflows. The PI40952-3X2B bridges this gap by utilizing a standard PCI Express x1 interface (compatible with x4, x8, and x16 slots). Delock PCI Express Card to 2 x Serial
If the manual installation wizard rejects the folder, the core architecture of the driver might lack a digital signature. To remedy this on newer platforms like Windows 10 or Windows 11, you must temporarily restart your computer with via the Advanced Startup options menu. This allows legacy, unsigned controller configurations to activate properly. Resource Allocation Conflicts (IRQ)
