Description
Black Box SWCX3655B 2-to-1 Local Remote Switch Serial Parallel Rackmount 1U
The Black Box SWCX3655B is a 2-to-1 local/remote data transfer switch that allows a single shared device — typically a printer, plotter, or other serial or parallel peripheral — to be selected between two host computers or data sources. Switching is accomplished via the front-panel rotary knob (positions A, B, and Remote) or by sending a remote command signal through the rear RJ remote port. The unit mounts in a standard 19-inch equipment rack and occupies 1U of rack space.

Applications
The Black Box SWCX3655B belongs to a category of manual and remote-switchable data transfer switches widely used in office, print room, and light industrial environments during the 1990s and early 2000s, when serial (RS-232) and parallel (Centronics/IEEE 1284) ports were the dominant interfaces for connecting computers to printers, plotters, label printers, and scanners. A 2-to-1 switch of this type lets two workstations share one peripheral without moving cables — the operator simply turns the front-panel knob or sends a remote signal to hand off the port. The Remote port allows the switch to be controlled by an external signal or a remote switching unit, which was useful in server rooms and rack environments where the front panel was not easily accessible. This type of switch is still useful today wherever legacy serial or parallel peripherals remain in service — particularly in manufacturing, laboratory instrumentation, point-of-sale, or industrial control settings where older equipment with DB25 connectors is still actively used.
This Black Box SWCX3655B 2-to-1 Local/Remote Serial Parallel Switch has been inspected and is in good condition. It was pulled from a working environment where it was in active use. The unit shows normal cosmetic wear — minor scuffing on the chassis and light corner wear on the right side panel, as seen in the photos. The front panel rotary selector, PWR LED, and indicator LEDs appear intact. The rear DB25 serial/parallel ports and RJ remote port look clean and undamaged. The included Black Box AC adapter (model PS154, JK-17701-NA) is present and attached. Please view our photo set and contact us if you have any questions.
