The Comtrol 95750-8 RocketPort is a 16-port serial communication card for PCI bus systems, delivering RS-232 and RS-422 connectivity in a single interface. Engineers deploy this card to expand serial port density in industrial automation, SCADA, data acquisition, and point-of-sale environments where high data throughput and reliable mission-critical communication are essential.
## Technical Specifications
**Serial Standards & Data Rates**
• RS-232: up to 115.2 kbps
• RS-422: higher speeds supported (dependent on cable length and signaling conditions)
• 128-byte transmit FIFO per port
• 128-byte receive FIFO per port
• Software-selectable RS-232 or RS-422 configuration per port
**Signal Levels**
• RS-232: EIA-232 compliant (±3V to ±15V swing)
• RS-422: EIA-422 compliant (differential signaling)
**Physical & Interface**
• Form Factor: 32-bit PCI card (3.3V or 5V signaling)
• Connector: DB37 female (requires breakout cable or panel for individual RS-232/RS-422 termination)
• I/O Addressing: Configurable via system BIOS or jumpers
• Interrupt Management: Configurable IRQ lines via PCI bus arbitration
## Key Features
• 16 independent serial ports in single PCI slot
• Per-port protocol selection eliminates need for multiple card types in mixed-interface deployments
• FIFO buffers reduce CPU overhead and maintain data integrity at higher baud rates
• Configurable interrupt and I/O addressing for flexible system integration
## Typical Applications
• Industrial control systems
• SCADA networks
• Data acquisition systems
• Point-of-sale terminals
## Compatibility & Integration
**Operating Systems**
• Windows (multiple versions)
• Linux
**PCI Bus**
• 32-bit PCI slots
• 5V or 3.3V signaling compatible
Driver support and OS-specific compatibility details require verification with Comtrol for your deployment environment.
