Two serial ports for legacy and industrial gear
The TeKit expansion card adds two DB9 RS232 ports through a PCI‑Express 1.0 x1 slot using the WCH382L chip. It targets IPC builders, telecom integrators, medical equipment technicians and POS installers who still drive engraving machines, cutting plotters, access-control panels or serial printers from a modern motherboard.
Passive cooling keeps the slot silent
The 60 g board draws power only from the PCI‑Express bus and has no fan or heatsink, so it adds no audible noise inside a chassis. The 1.0 link runs at 2.5 Gb/s full duplex, and the 16C550‑compatible UARTs provide 256‑byte FIFOs that keep CPU interrupts low during normal RS232 traffic.
Sustained transfers hold at 250 kb/s per port
Each channel supports hardware flow control and data lengths of 5 to 8 bits, allowing continuous streams up to the rated 250 kb/s without overflow. Remote wake‑up and power‑management features let the host sleep between bursts, while driver support spans Windows 98 SE through Server 2012 plus Linux for long‑term deployments.

이 상품에 대한 질문
How is the PCI-E 1.0 x1 card seated, and which step is often missed?
Insert the card into an available PCI-Express slot, secure the bracket screw, then install the WCH382L driver for Windows or Linux before the ports appear.
What maintenance or replacement will the DB9 RS232 ports need over time?
The DB9 connectors and RS232 level shifters are solid-state; only the slot retention screw or a loose cable may need occasional re-tightening.
What limit appears first when both COM ports run at 250k b/s continuously?
The PCI-E 1.0 x1 link caps total throughput at 2.5 Gb/s, so sustained dual-port traffic stays well within the 256-byte FIFO buffer capacity.
