Comtrol 95750-8 RocketPort 16-Port RS-232 / RS-422 PCI Card

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 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.
