Seriële PCIe-kaart Exsys EX-46028 — 8-poorts RS-232 met octopus-kabel

The Exsys EX-46028 is a PCIe serial expansion card that provides eight RS-232 ports and is supplied with an octopus cable to connect multiple DB9 serial devices. Built for industrial and legacy-peripheral applications, the card fits into a standard PCIe slot and enables simultaneous serial communication for devices such as point-of-sale terminals, automation controllers, external modems and various sensors. The design focuses on reliable multi-device interfacing to expand a system's I/O capabilities without changing host hardware architecture.

Advantages

This PCIe card offers eight independent RS-232 channels on a single board, reducing the need for multiple expansion devices. The included octopus cable simplifies wiring by consolidating connections to DB9 serial devices and helps organize cabling in tight installations. Compatibility with standard RS-232 signaling ensures support for a wide range of legacy and industrial peripherals, while the PCIe form factor retains system stability and throughput for reliable serial data transfer.

Suitable for

• Point-of-sale systems requiring multiple serial peripherals
• Industrial automation and machine control with legacy serial interfaces
• Connection of external modems and telemetry devices
• Laboratory equipment and sensor networks using RS-232

Key specifications

• Interface type: PCI Express slot
• Serial ports: 8 x RS-232 channels
• Cable: Octopus cable with DB9 connectors for multi-device connection
• Data signaling: Standard RS-232 voltage levels and control lines
• Form factor: Low-profile/standard PCIe bracket compatibility (fits PCIe slot)

How to use

Install the card into an available PCIe slot on a powered-down system following the host platform's safety procedures. Secure the card to the chassis and route the supplied octopus cable to connected DB9 devices. Attach each DB9 connector to its respective serial peripheral and configure serial port parameters (baud rate, parity, data bits, stop bits, and flow control) in the host operating system or application software. Install any required drivers provided by the system or vendor to enable the OS to recognize and manage each serial channel.

Recommendations

For stable operation in industrial settings, use shielded DB9 cables and avoid routing serial lines parallel to high-voltage or high-frequency power cabling. Configure appropriate baud rates and flow control for each device to prevent buffer overruns, and verify driver compatibility with your operating system before deploying in production.
