The ATEN AS-8144B is a 4-port parallel auto switch designed for legacy parallel device connectivity and control. Part Number AS-8144B; features four DB-25 Bitronics parallel ports supporting bidirectional data transfer typical of legacy printing and peripheral equipment. The unit automatically detects and routes data to available ports, eliminating manual switching during multi-device environments. Compatible with systems requiring Centronics or IEEE 1284 parallel protocol support, the AS-8144B suits retrofit deployments, legacy equipment rooms, and environments where parallel-connected printers or external storage devices remain in service. Form factor is compact rackmount-ready. Typical throughput reaches standard parallel speeds (up to 2 Mbps bidirectional). Common applications include print farm automation, legacy workstation environments, and industrial control systems reliant on parallel I/O. Unit is refurbished, tested, and guaranteed; available via quote.
