IC104SA is a PCI multi-port serial card developed by ATEN. It supports RS-232 protocol, supports 3.3V and 5V, and is compatible with 64/32-bit PCI buses. IC104SA can be connected to DB-9 or 25-pin serial ports through RJ-45 interface, and is suitable for POS, ATM and industrial automation applications.
The ATEN IC104SA is a PCI 32‑bit RS‑232 multi‑port serial adapter that adds four RJ‑45 ports (DB9M/DB25M) to a PC. It supports both 3.3 V and 5 V PCI slots, 32‑bit or 64‑bit buses, and offers high‑speed baud rates up to 921.6 Kbps with a 128 KB software FIFO to reduce CPU load.
The manual guides you through hardware installation, driver installation for Windows, Linux and DOS, verification of the card in Device Manager, and COM‑port configuration including flow‑control and FIFO settings. It also lists the technical specifications and warranty information.
