Description
Computer Concepts 4624 Rackmount Data Switch RS-232 Centronics Parallel Ports
The Computer Concepts Corporation 4624 is a 2U rackmount data switch designed to share a single computer or multiple peripherals across selectable output ports. The front panel features a numbered keypad matrix for selecting between inputs and outputs, with labeled rows for CPU and printer connections. It provides both RS-232 serial and Centronics parallel connectivity, making it suitable for environments where multiple computers needed to share printers or other parallel/serial peripherals.

Applications
Data switch boxes like the Computer Concepts 4624 were standard equipment in offices and data centers from the late 1980s through the mid-1990s, before network-based printer sharing became the norm. They allowed multiple workstations or computers to share a single printer, plotter, or other parallel/serial peripheral — or conversely, allowed one computer to route output to any one of several attached devices. The front-panel keypad gave operators direct, manual control over which input was connected to which output without needing software or a network. These switches were commonly used with IBM PCs and compatibles, minicomputers, and dedicated word-processing systems in print rooms, pre-press environments, and office automation setups of that era. Hobbyists, vintage computing enthusiasts, and facilities still running legacy parallel-port equipment continue to seek out units like the 4624 today.
This Computer Concepts 4624 Rackmount Data Switch was pulled from a working environment where it was previously in use. The unit has been visually inspected and is physically complete. The aluminum housing shows surface scuffing and general handling wear consistent with rack service, and the front panel labels and keypad buttons appear intact. All rear connectors — RS-232, Centronics parallel, and Digital I/O ports — are present and show no obvious damage. Please view our photo set and contact us if you have any questions.
