8-port High-speed RS-232 PCL-858 Series Communication Card 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 Introduction • Speed: 50 ~ 921.6 Kbps PCL-858 series interface cards provide eight RS-232 serial communication ports. Each port can be configured individually using • Data signals: TxD, RxD, RTS, CTS, DTR, DSR, DCD, GND on-board jumpers. PCL-858A/858B cards each have two 16C554 DC • Surge protection: 3000 V (PCL-858B/858+) 6 UARTs, which make serial I/O more reliable. The higher performance • Power consumption: PCL858+ has two 16C654 UARTs. By buffering data into 64-byte +5 V @ 450 mA typical, 950 mA max. packets before putting it on the bus, UARTs drastically reduce the ±12 V @ 140 mA typical, 240 mA max. CPU load. This makes the PCL-858+ especially suitable for high- speed serial I/O applications under multitasking environments and for • Dimensions: 18.5 cm × 10.0 cm applications involving high data rates. • Operating Temperature: 0 ~ 60° C (32 ~ 140° F) PCL-858 series cards support automatic addressing for all eight • Storage Temperature: -25 ~ 80° C (-13 ~ 176° F) ports. All channels share the same interrupt (IRQ), and an interrupt status register can be used to determine the interrupt source.
