Any Address, Any IRQ,

RS-232 Serial Cards CE

Overview

B&B Electronics’ 232CC series RS-232 serial interface cards provide the flexibility needed to fit into today’s complex communication systems. Designed for the IBM PC, XT, AT and compatibles, the 232CC card ports may be independently configured for any I/O address and any available hardware interrupt. Ports are configured as a standard DTE device, and connections are made on 9-pin male D-style connectors.

The 232CC cards now feature Enhanced Address Decoding, which decodes the entire 16-bit address bus, versus the 10 bits traditionally used by serial cards. This feature minimizes hardware conflict potential by eliminating shadowing of the serial port at higher addresses, eliminating the COM 4 - video card conflict. Also featured on the 232CC cards is a clock doubling feature which allows each port to communicate at up to 230.4 Kbaud when enabled. This option doubles the baud rate set by the software.

High speed 16550A UARTs come standard with the 232CC series cards. Optionally, the new 16850 UART is available, featuring 128-byte transmit and receive FIFO’s and full 16450 and 16550A compatibility. NOTE: to enable these enhanced features, the driver software must support the 16850.
