Serial cable DeLOCK 87835 1.8m DB9 male to DB9 male

The DeLOCK 87835 serial cable is a 1.8 meter DB9 male-to-DB9 male cable designed for reliable serial communication between compatible devices. It provides a straightforward wired connection for RS-232 interfaces commonly found on computers, industrial devices, printers, routers, and instrumentation equipment. The cable supports point-to-point data exchange and is suitable for both temporary connections and longer-term installations where a physical serial link is required.

Advantages

The cable features two DB9 male connectors that fit standard serial ports and maintain stable signal transmission over the full 1.8 m length. Its construction is focused on dependable electrical contact and consistent pin assignment to avoid wiring mismatches. The flexible jacket permits easy routing through equipment racks and along work surfaces while preserving connector integrity during repeated insertions and removals.

Suitable for

• Connecting computers to serial peripherals such as printers and modems
• Linking industrial controllers, PLCs, and measurement instruments
• Configuring network equipment and routers via console ports
• Serial data transfer between laboratory devices and data loggers

Key specifications

• Cable length: 1.8 m
• Connector type: DB9 male to DB9 male
• Interface standard: RS-232 compatible
• Contact arrangement: 9-pin
• Jacket: flexible insulating sheath for indoor use

How to use

Connect each DB9 male connector to the corresponding female serial port on the devices you wish to link. Ensure both devices are powered off or their serial ports are inactive while plugging in to prevent transient signals. After connection, configure the serial parameters (baud rate, data bits, parity, stop bits, flow control) on both devices to match. Verify communication using terminal software or device-specific diagnostics and test simple commands or data transfer to confirm signal integrity.

Recommendations

For reliable long-term operation, avoid routing the cable near high-voltage power lines or sources of strong electromagnetic interference. Use secure mounting or cable ties to prevent strain at connector ends and periodically inspect connectors for bent pins or corrosion when used in industrial or dusty environments.
