InLine sériový prepínač manuálny 4-port RS232 9-pól Sub-D káblový

The InLine Serial switch manual 4-port RS232 9-pin Sub-D Wired is a mechanical data switch that allows splitting or switching of serial RS232 signals through a 9‑pin Sub-D connector. It connects one input to up to four outputs, or routes one of four inputs to a single output, without requiring an external power supply. The device occupies the connector shielding and provides a compact solution for managing multiple serial connections.

Advantages

This manual 4-port RS232 switch requires no power, offers simple mechanical switching between one input and four outputs (or vice versa), and uses a standard 9‑pin Sub-D interface for compatibility with typical RS232 equipment. Its compact wired design and black finish make it suitable for desktop and rack-mounted environments where manual switching of serial lines is needed.

How to use

Connect the RS232 host device to the input Sub-D connector and connect up to four target devices to the output Sub-D connectors. Operate the manual switching mechanism to select which output is connected to the input (or which input is routed to the output). Ensure connectors are fully seated and fastened to maintain signal integrity. No power or drivers are required for operation.

Recommendations

Use this switch for low‑speed serial communication and manual selection tasks. Avoid hot‑plugging devices under heavy data transfer; disconnect or pause communication before switching to prevent data corruption. Verify pinout compatibility with connected equipment to ensure proper signal routing.
