Serial cable DeLOCK 88219 1.8m DB9 male to DB9 male

The DeLOCK 88219 serial cable is a 1.8 meter DB9 male to DB9 male cable designed for reliable RS‑232 serial communication between compatible devices. It provides a straightforward wired connection for transferring data and control signals between computers, industrial equipment, legacy peripherals and serial-enabled instruments where a standard 9‑pin D‑sub male interface is required.

Advantages

This 1.8 m DB9 male to DB9 male cable offers stable signal transmission and solid mechanical connection thanks to its standardized D‑sub connectors. The cable length balances reach and signal integrity for typical desktop, workshop or rack-mounted setups. Constructed for compatibility with common serial ports, it supports point‑to‑point communication without the need for adapters, making it suitable for straightforward integration into existing serial-based systems.

How to use

Connect each DB9 male connector to the corresponding female DB9 serial port on the two devices you wish to link. Ensure that both devices are powered off or in an appropriate configuration state before plugging in to avoid signal errors. After connection, power on the devices and configure serial communication parameters (baud rate, parity, data bits, stop bits and flow control) on both ends to match. If required by the devices, use cross‑over (null‑modem) wiring or adapters; this cable provides a standard straight through DB9 male to DB9 male connection.

Recommendations

For reliable long‑term performance, avoid sharp bends near the connector ends and secure the cable to reduce strain. Verify serial port settings and pinout compatibility before use; when connecting devices that require null‑modem wiring, confirm whether a crossover adapter is needed. Keep the cable clear of high‑interference power cables to preserve signal integrity.
