SMUGDESK

SMUGDESK PCIe RS232 LPT Combo Card WCH382 Low Profile

SKU CH-5J8Z-Z7K7K

Adds one RS232 serial port and one IEEE 1284 parallel port via PCIe using a WCH382 chip, includes low-profile bracket for Windows 10 systems

  • Adds RS232 serial and LPT parallel ports via single PCIe slot
  • WCH382 chip provides strong anti-interference for stable operation
  • Includes both standard and low-profile brackets for any case
  • Works with Windows 10 and other mainstream desktop OSes
  • Connects legacy printers, POS gear and industrial controllers

Legacy I/O Expansion Card

This PCIe card adds one RS232 serial port and one IEEE 1284 parallel port to a desktop PC using a WCH382 controller chip. It targets users who need to connect older printers, scanners, POS terminals or industrial equipment to a modern system.

Fits standard and low-profile cases

The included low-profile bracket allows installation in small-form-factor chassis as well as full-size towers. Buyers whose motherboards lack a free PCIe slot or who require USB-based connectivity should consider alternative adapter types.

WCH382 chip with Windows 10 support

The onboard WCH382 controller provides stable, anti-interference operation for both serial and parallel interfaces under Windows 10. Verify that your operating system and legacy software support this chip before purchase.

Questions about this item

How do I install the SMUGDESK PCIe RS232 LPT Combo Card and which bracket should I use?

Insert the card into a free PCIe slot, secure it with the screw, then attach either the standard or low-profile bracket to match your case height; the step people miss is choosing the bracket before mounting.

What maintenance or replacement will the WCH382 chip and ports need later?

The WCH382 controller and the RS232 and IEEE 1284 ports are solid-state with no moving parts, so no scheduled maintenance is required; only replace the card if a port fails or the system no longer recognises it.

What limit appears first under sustained use of the RS232 and LPT ports?

The practical limit is the legacy signalling speed of the RS232 and IEEE 1284 interfaces themselves; sustained throughput will plateau at the maximum rate those standards allow.
