Vszerda PCIe to 8-Port RS232 Expansion Card

SKU CH-TR4H-1C3M9

Adds eight RS232 DB9 serial ports via a PCI Express slot

  • Adds eight serial ports via PCI Express
  • Each port uses a DB9 connector
  • Eight independent chipsets handle the channels
  • Supports RS232 signalling at 232

Eight independent serial ports

This PCI Express card adds eight RS232 DB9 ports to a desktop or server system. Each port is driven by its own chipset, providing separate interrupt and I/O resources for reliable multi-device connectivity. It suits industrial automation, laboratory instruments and legacy equipment that still rely on standard serial communication.

Sustained multi-port throughput

Because every channel has a dedicated controller, the card maintains consistent data flow across all eight ports simultaneously without the contention seen on shared-controller designs. This architecture keeps latency predictable during long logging sessions or continuous polling cycles. Builders who need more than eight concurrent serial links or a different physical interface will require an alternative solution.

Questions about this item

Does the eight-port card generate much heat or noise when all ports run continuously?

The card uses eight individual UART chips and has no moving parts, so it runs silently with only modest warmth during full-load operation.

What motherboard slot must be free for this expansion card?

An open PCI Express slot is required; the card draws its power and data directly from that slot.
