InLine Serial switch manual 2-port RS232 9-pin Sub-D Wired

This manual data switch allows simple splitting or routing of serial signals and similar connections via a 9‑pin Sub‑D (SUB-D) interface between one input and two outputs, or vice versa. Switching is performed mechanically without the need for an external power supply. The device uses the connector's shielding for continuity.

Advantages

The mechanical switch requires no power, ensuring reliable operation in environments without available supply. Its simple Sub‑D connection makes it compatible with many serial devices and communication cables. The compact, passive design provides straightforward signal routing without configuration.

Key specifications

• Connector type: 9‑pin Sub‑D (DB9)
• Function: Manual switching between 1 input and 2 outputs or vice versa
• Power requirement: None (mechanical switching)
• Shielding: Connector shielding used for continuity
• Application: Serial signals and similar interfaces

How to use

Connect the serial source to the input Sub‑D connector and the target devices to the two output Sub‑D connectors (or reverse for combining). Operate the mechanical switch to select which output is connected to the input. No electronic setup or power connection is necessary. Ensure connectors are seated firmly to maintain signal integrity.

Recommendations

Use with compatible serial cables and devices; verify pinouts when interconnecting different equipment to avoid signal mismatch. Avoid exposing the switch to moisture or excessive mechanical stress.
