Description
Product Overview
The StarTech Serial Port Card is engineered for dependable serial communication in demanding industrial and commercial settings. Measuring 6.89 x 5.71 x 1.26 inches and weighing just 1.92 ounces, the card fits comfortably into standard expansion slots. It features a 16C1050 UART chipset capable of a maximum data transmission rate of 128 Kbps and a 256‑byte deep FIFO buffer, which together minimize latency and prevent data loss during burst transfers. The card supports both 2‑wire and 4‑wire RS485 modes, as well as RS422, with jumper pins that let users toggle between configurations without tools. Integrated hardware and software flow control further safeguard data integrity, while the English language interface and clear labeling simplify installation and maintenance.
Usage
Designed for environments where reliable serial links are critical, this card excels in factory automation, PLC networking, point‑of‑sale terminals, and remote monitoring stations. Its compact form factor makes it suitable for tight enclosures, and the low power consumption ensures stable operation even in energy‑constrained installations. Technicians and system integrators will appreciate the straightforward jumper settings for RS422/RS485 mode selection, allowing rapid adaptation to varying field bus standards. Whether deployed in a temperature‑controlled server room or a rugged manufacturing floor, the card delivers consistent performance.
