This unit
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.
