Serial adapter cable Logo DB-9 to DB-25, gray (68011)

Logo DB-9 to DB-25 serial adapter cable in gray provides a simple physical connection between devices equipped with 9-pin (DB-9) and 25-pin (DB-25) D-sub serial ports. Designed for RS-232/serial communications, the adapter enables direct data transfer, diagnostics, programming and control of legacy and industrial equipment that require a different connector format without changing cabling or internal wiring.

Advantages

The adapter cable offers a compact and practical solution for converting between DB-9 and DB-25 connectors while maintaining the required serial signal lines. Its gray molded jacket and strain-relief ends reduce mechanical stress at the connector interface. The passive cable requires no external power or drivers, allowing immediate use with standard serial ports and terminal equipment. The fixed wiring preserves signal integrity for short to moderate cable runs in typical RS-232 environments.

Suitable for

• Connecting PCs, laptops or serial terminals with DB-9 ports to printers, modems or test equipment with DB-25 ports
• Interfacing industrial controllers, PLCs and legacy instrumentation that use RS-232 connectors
• Diagnostic and programming tasks on equipment that require a DB-25 connector
• Laboratory and workshop setups where occasional connector adaptation is needed

Key specifications

• Connector types: 9-pin D-sub (male or female as required) to 25-pin D-sub (male or female as required)
• Cable color: gray
• Purpose: RS-232 / serial signal adaptation between DB-9 and DB-25
• Construction: molded connectors with strain relief for mechanical durability
• Type: passive adapter cable, no electronics or power supply

How to use

Align the appropriate DB-9 and DB-25 connectors and fasten the thumbscrews or fastening hardware to ensure a secure mechanical connection. Verify pin orientation and connector gender before connecting to avoid mis-wiring; then attach the cable between devices and configure serial port settings (baud rate, parity, data bits, stop bits) on both ends as required by the equipment. After use, disconnect by loosening the screws and gently removing the connectors to prevent stress on the cable.

Usage recommendations

Use this adapter for short to moderate RS-232 cable runs and in environments free from excessive electrical noise. For critical or long-distance serial connections consider using shielded cabling, proper grounding and, if needed, active line drivers or repeaters to maintain signal integrity.
