Serial PCIe Card Exsys EX-46024 — 4× RS-232 ports with Octopus cable

Exsys EX-46024 is a PCIe serial expansion card that adds four RS-232 ports to a desktop or industrial PC. Supplied with an Octopus cable, the card provides a single PCIe-bracket connection that splits into four standard DB9 serial connectors, enabling straightforward attachment of legacy equipment. The product is intended for systems with an available PCIe slot and offers a stable, low-level serial interface for applications such as data logging, device control and system integration.

Advantages

The card provides four independent RS-232 interfaces from one PCIe slot, reducing the need for multiple adapters or external hubs. Inclusion of the Octopus cable simplifies cabling by delivering four DB9 connectors on a single lead, which is convenient for mounting and routing inside racks or industrial enclosures. Using a PCIe expansion ensures direct, low-latency communication suitable for equipment that requires reliable serial signaling.

Suitable for

• Connecting modems and serial communication devices
• Point-of-sale (POS) terminals and receipt printers
• Measurement instruments and laboratory equipment
• Industrial controllers, PLCs and automation interfaces
• Data logging and system integration tasks requiring RS-232

Key specifications

• Interface type: PCI Express (PCIe) expansion card
• Serial ports: 4 × RS-232
• Connector: Octopus cable with four DB9 male/female serial connectors
• Form factor: standard bracket for desktop or industrial PC installation
• Typical use: low-latency serial communication for legacy devices and industrial equipment

How to use

Install the EX-46024 into an available PCIe slot on a powered-down PC, secure the card to the chassis with the bracket screw, and connect the Octopus cable to the card’s header or bracket connector as delivered. After powering on the system, install any required drivers supplied by the system or manufacturer and verify that each RS-232 port appears in the operating system’s device manager or serial port list. Connect your serial devices to the DB9 connectors, configure port parameters (baud rate, parity, data bits, stop bits, flow control) in the host application or terminal software, and test communication with the device-specific protocol.

Recommendations

For reliable operation, use quality shielded serial cables and keep cable runs as short as practical to reduce interference. Ensure proper driver installation and verify COM port assignments before deploying in production. When connecting to industrial equipment, confirm voltage and signal compatibility with RS-232 levels and consider using surge protection or isolation if the environment includes large electrical noise or potential ground differentials.
