If you give me that, I can track down the exact datasheet and write up the (pinout, application circuit, voltage range, control logic).
Once identified, run the installer from the manufacturer links above. Technical Specifications Delock PCI Express Card to 2 x Serial pi40952 3x2b driver
| Pin Group | Labeling | Description | |-----------|----------|-------------| | Power Input | VIN, GND | Main supply and ground plane. Requires a 10µF-100µF decoupling capacitor. | | Control Inputs (Channel A) | A0, A1 | 2-bit binary command for output A. | | Control Inputs (Channel B) | B0, B1 | 2-bit binary command for output B. | | Control Inputs (Channel C) | C0, C1 | 2-bit binary command for output C. | | Output Pins | OUTA, OUTB, OUTC | Each pin connects to the load (motor, solenoid, etc.). | | Enable | EN | Global enable (active high). Pulling low puts all outputs in a high-impedance state. | | Fault Indicator | nFLT | Open-drain output that pulls low during overcurrent or overtemperature. | If you give me that, I can track
Power down your PC, unplug it from the wall, and open the case. Requires a 10µF-100µF decoupling capacitor
Locate the flagged entry under (often labeled PCI Serial Port or PCI Simple Communications Controller ).
Most driver complications with the PI40952-3X2B originate in how this chipset is configured (explained in detail in Section 5).
Unified cards offering two serial connections alongside a parallel interface.
