Serial Cable DeLOCK 87838 1.8m DB9 Male to DB9 Male

The DeLOCK 87838 serial cable is a 1.8 meter DB9 male-to-male cable designed to provide a stable wired connection between devices with RS-232-style serial ports. Built for straightforward point-to-point data transfer, this cable supports common serial communication needs in industrial equipment, legacy computers, routers, switches, and other peripherals that use 9-pin D-sub connectors. The cable's fixed pinout and robust connector housings make it suitable for routine data exchange and configuration tasks.

Advantages

This DB9 male-to-male cable offers a reliable physical connection with solid contact pins and molded strain-relief at each end to reduce wear from repeated insertion and movement. The 1.8 m length balances reach and cable management for typical bench or rack installations. Its standardized 9-pin D-sub connectors ensure compatibility with devices using the common serial interface, delivering consistent signal transmission for configuration, diagnostics, and control applications.

Подходит для

• Соединение маршрутизаторов, коммутаторов и другого сетевого оборудования для настройки и управления
• Подключение промышленного оборудования и контроллеров с 9-контактными D-sub портами
• Обмен данными между компьютерами и периферией с последовательными портами
• Использование в сервисных задачах для диагностики и прошивки устройств

Key specifications

• Connector type: DB9 (9-pin D-sub) male to male
• Cable length: 1.8 m
• Connector housing: molded with strain relief
• Contact finish: standard metal contacts for serial signal transmission
• Typical use: RS-232 style serial communication

How to use

Connect one DB9 male connector to the serial port of the first device and the other DB9 male connector to the second device. Ensure both devices share compatible serial settings (baud rate, parity, data bits, stop bits and flow control) before initiating communication. Secure the connectors by tightening the thumbscrews if present to maintain a stable connection. For best results, route the cable away from high-voltage power lines or sources of electromagnetic interference to reduce noise on the serial signals.

Usage recommendations

For reliable operation, verify device compatibility with DB9 male-to-male wiring and confirm required signal levels and pinout mapping. Inspect connector housings and strain relief periodically for signs of wear; replace the cable if pins appear bent or contacts are loose. Avoid sharp bends and excessive tension to preserve signal integrity over time.
