PCIe 2x Parallel Controller Longshine LCS-6320A, 2 parallel ports

Longshine LCS-6320A is a PCIe expansion controller that provides two parallel ports for connecting legacy parallel-interface devices to modern PCs. The card installs into a PCI Express slot and exposes two DB25 parallel connectors on the rear bracket, restoring connectivity for printers, industrial controllers, measurement instruments, and other devices that require parallel communication. The design focuses on straightforward hardware integration and compatibility with systems where onboard parallel ports are absent.

Advantages

The PCIe 2x parallel controller supports two independent parallel ports, enabling simultaneous connection of multiple legacy devices without relying on adapter cables. Its PCIe form factor allows installation into standard desktop PCs with available PCI Express slots, and the external bracket provides accessible rear-panel connectors. The card facilitates continued use of existing parallel peripherals, reducing the need for device replacement and preserving established workflows.

Suitable for

• Connecting parallel-port printers in office or production environments
• Linking industrial controllers and automation devices that use parallel interfaces
• Interfacing laboratory and measurement equipment with parallel outputs
• Restoring connectivity for legacy peripherals on modern motherboards without parallel ports

Key specifications

• Interface: PCI Express x2 card
• Ports: 2 external DB25 parallel connectors
• Compatibility: Designed for standard desktop PCIe slots and parallel-interface peripherals
• Form factor: Low-profile bracket compatible with many chassis (check slot and bracket space)
• Function: Adds bidirectional parallel ports for data and control signal exchange

How to use

Install the card into an available PCI Express x2 or larger slot on the motherboard following static-discharge precautions. Secure the bracket in the chassis rear panel and connect parallel peripherals to the DB25 connectors. Boot the system and install any manufacturer-supplied drivers or use the operating system’s built-in parallel port support if applicable. Configure device settings in the operating system or application software to match the peripheral’s communication parameters.

Usage recommendations

Verify physical clearance and slot compatibility before installation, and ensure drivers are up to date for your operating system. For reliable communication with industrial or timing-sensitive equipment, use shielded cables of appropriate length and follow the peripheral manufacturer’s connection guidelines.
