HP WCH382 PCIe Serial Card

This HP expansion card adds two 16C550 UART serial ports via a 32-bit PCI interface. It uses the WCH382 chipset and includes a low-profile bracket for compact chassis. Driver support covers Windows 2000 through 11 and Linux 32-bit and 64-bit systems.

Who This Suits and Who It Does Not

Suits users connecting legacy RS-232 equipment such as industrial controllers, modems or point-of-sale devices to a modern PC. Not for buyers needing USB, parallel or multi-I/O connectivity, or those whose motherboards lack a 32-bit PCI slot.

Deciding Specification: 32-bit PCI Bus

The card installs only in a 32-bit PCI slot; it will not fit PCI-Express x1, x4, x8 or x16 sockets. Verify the motherboard provides a classic PCI connector before purchase.

Questions about this item

Does the WCH382 chipset cap throughput at 230400 bps during long transfers?

The WCH382 chipset supports data transfer rates up to 230400 bps per 16C550 UART port, so sustained serial traffic will not exceed that figure.

How much heat or power does the card add when both COM ports run continuously?

The card weighs 0.018 kg and draws power only from the PCI Express x1 slot, adding negligible heat inside the chassis.

Which slot type must my motherboard provide for this card to work?

A free PCI Express x1 slot is required; the package also includes a low-profile bracket for small-form-factor cases.
