INTRODUCTION
PPCL-858 series interface cards provide eight RS-232 serial communication ports. Each port can be configured individually using on-board jumpers. PCL-858A/858B cards each have two 16C554 UARTs, which make serial I/O more reliable. The higher performance PCL858+ has two 16C654 UARTs. By buffering data into 64-byte packets before putting it on the bus, UARTs drastically reduce the CPU load. This makes the PCL-858+ especially suitable for high-speed serial I/O applications under multitasking environments and for applications involving high data rates.
FEATURES
Eight independent RS-232 serial ports Transmission speed up to 921.6 Kbps Independent I/O addresses, shared IRQ settings for each of 8 serial ports Wide IRQ selection: 3, 4, 5, 6, 7, 9, 10, 11, 12, 15 Supports DOS/Windows 3.1 (PC-ComLib), Windows 95/98, Windows NT (ICOM Utility) Supports surge protection: 3000 VDC (PCL-858B/858+) PC-ComLib software and ICOM Utility included
