Introduction

The BPS 4221S and 4222S are high-performance RS-422 video controller cards with 16C550-style UARTs which feature 16-byte transmit and receive buffers to help guard against loss of data in your busy system. The card may be addressed as COM1: to COM4: or any other I/O address you choose from 000 up to 3F8 hex. The backplate has up to four standard DB-9 female (9-pin) connectors.

All ports are capable of operating at speeds up to 920 kbps, making these units ideal for high-speed applications such as ISDN modems.

Interrupt Sharing: The Key to Adding Many Serial Ports

The powerful interrupt feature allows multiple ports on a single card to use the same interrupt. With this technology, up to four ports in one system (when using the BSP 4224V) can share one interrupt. Any of eleven interrupt choices are available for each port. The interrupt status register may be located at any address, and when used with interrupt sharing, it will supply you with a pointer to indicate which port has an interrupt pending. This feature allows you to find out which of up to four ports has a pending interrupt with only a single read operation.

Our serial cards are compatible with all application software that communicates with a standard serial port using an 8250 or 16C450 UART (the UARTs which virtually all PC's use for serial ports). This includes compatibility with Windows 3.x/95/98/NT/ME/2000/XP, OS/2, UNIX, and XENIX. An NT setup disk is provided with the 4-port unit to make your Windows NT installation and registry modifications a breeze.

Our video deck controller cards feature female DB-9 pinout which supports a direct connection to popular video (VTR) decks. Each port may be switched via a jumper from being a controller to appearing as a VTR deck.
