- RJ11 multi-port serial expansion using a single PCIe slot maximizes host expansion capabilities; adds additional COM ports using only one slot
- PCI EXPRESS x1, x2, x4, x8, x12 and x16 lane connectivity
- Low-latency communication supporting the widest variety of applications
- RS-232, RS-422, and RS-485 software-selectable
- On-board dedicated 44MHz RISC processor minimizes “host” CPU utilization
- Edge-mounted RJ11 serial ports provide cost-effective, compact serial connections
- Transmit and receive buffers 32 times larger than a standard 16550 UART-based serial card ensuring smooth, efficient data transfer
- Support for the most popular Windows operating systems (including Windows® 10) and Linux kernels and QNX 6.X
- Windows driver, which can be configured for interrupt or polling mode
- Free troubleshooting tools in the event you want to diagnose an issue: Hardware diagnostics, LCOM (Linux tool for testing serial ports), Comtrol Utility, which includes Test Terminal (WCOM2) for serial port testing and Port Monitor for monitoring ports
Comtrol’s RocketPort EXPRESS 8J serial port expansion card provides eight “native” serial ports utilizing a single PCIe card slot and is compatible with all PCI Express bus architectures. The RJ11 serial ports, mounted on the edge of the card, support software configurable RS-232/422/485 serial communications at speeds up to 921.6 Kbps.
Every RocketPort serial card features the high-performance RocketPort processor chip, consisting of a dedicated 44MHz core that minimizes host CPU utilization and optimizes data transmission via larger transmitand-receive buffers than those of 16550 UART chips, commonly used in standard PC serial ports and low-end serial cards.
RocketPort technology enables these cards to outperform other serial expansion cards by handling the transmission of large amounts of data more reliably and efficiently.
Certified Windows drivers, support for the most popular operating systems, and readily available U.S.-based support makes the RocketPort 8J the perfect solution for projects requiring PC-based serial communication.
