The Digi AccelePort 8r 920 is an eight-port serial PCI card engineered for high-performance serial connectivity in B2B environments. This card facilitates communication between diverse serial devices, delivering reliable data transfer and device management across laboratories, industrial settings, and enterprise networks. Each of the eight RS-232 ports operates independently and is configurable for baud rate, data bits, parity, and stop bits, supporting data rates up to 115.2 kbps per port.
Technical Specifications
• Ports: 8 RS-232 serial ports
• Host Interface: PCI (Peripheral Component Interconnect)
• Data Transfer Rate: Up to 115.2 kbps per port (configurable)
• FIFO Buffers: Transmit and receive FIFO buffers to reduce host CPU load and improve throughput
• Interrupt Management: PCI interrupt sharing for efficient resource utilization
• Operating Voltage: +5V and +3.3V supplied by PCI bus
• Form Factor: Standard PCI card
– Key Features
• Eight independent RS-232 serial channels with individual port configuration
• FIFO buffer support for improved data throughput and reduced processor overhead
• PCI interrupt sharing capability for efficient host integration
• Operates on standard PCI bus power without external supply requirements
– Typical Applications
The AccelePort 8r 920 interfaces with modems, printers, scanners, industrial control equipment, and legacy serial peripherals where multiple serial connections are required within a single host system.
– Compatibility & Integration
The card is compatible with PCI 2.1 and later specifications. Operating system support includes Windows, Linux, and macOS. Installation into any standard PCI slot requires OS-specific drivers for the target platform.
