Overview
PL-2305 USB TO IEEE1284 BRIDGE CONTROLLER Bi-Direction Parallel Interface OVERVIEW The PL-2305 USB-to-IEEE-1284 Bridge Controller is a low-cost high-performance single chip solution that provides bi-directional connectivity between any standard IEEE-1284 compliant parallel port devices and the Universal Serial Bus (USB) interface.
Software drivers for Microsoft Windows 98 and NT 5.
0 are also provided to create a seamless migration path from traditional parallel port to the USB environment.
The PL-2305 is based on Prolific Technology’s USB Universal Parallel Bridge Controller (U-PBC) Dual-Thread Micro-Controller.
With 512 bytes of unified data buffer, it is capable of providing maximum throughput for both upstream and downstream data transfer for a wide variety of devices.
The IEEE-1284 interface of PL-2305 is robust enough to handle various not-so-compliant parallel port implementations.
