DELOCK Adapter Cable OBD‑2 Male to DB‑9 Female, Cat5e, Black, 1.15 m

The DELOCK Adapter Cable OBD‑2 Male to DB‑9 Female, Cat5e, Black, 1.15 m provides a straightforward physical connection between a vehicle's OBD‑2 port and equipment with a DB‑9 serial interface. It uses Cat5e wiring to map the OBD‑2 signals to a Sub‑D 9 pin female connector for serial communication and diagnostic tasks. The 1.15 m black cable is intended to link data loggers, diagnostic tools or other devices that require a DB‑9 serial input to vehicles equipped with an OBD‑2 port.

Advantages

This adapter offers a compact, ready‑made cable solution that eliminates the need for custom wiring when connecting OBD‑2 ports to DB‑9 serial devices. Using Cat5e wiring ensures standardized signal pairing and consistent electrical characteristics for short serial and diagnostic connections. The straight male OBD‑2 plug and straight DB‑9 female connector with mounting screws provide a stable mechanical and electrical connection during testing or monitoring.

Suitable for

• Connecting vehicle OBD‑2 ports to DB‑9 serial diagnostic tools or data loggers
• Vehicle monitoring and logging tasks that use serial interfaces
• Reading and resetting fault memory via CAN, J1850 or K/L‑line interfaces when adapted to serial equipment

When it may not be suitable

This adapter is intended for signal-level mapping between OBD‑2 and DB‑9 serial interfaces and does not provide protocol conversion, USB interfacing, or vehicle power conversion. It may not be appropriate if your diagnostic device expects a different physical interface (e.g., USB, proprietary connectors) or if active signal level shifting or protocol translation is required.

Key specifications

• Cable length: 1.15 m
• Cable wiring: Cat5e
• Connectors: OBD‑2 straight male to DB‑9 (Sub‑D 9 pin) straight female with mounting screws
• Color: Black
• Intended use: Serial communication and diagnostic interfaces

How to use

Plug the OBD‑2 male connector into the vehicle's OBD‑2 port and attach the DB‑9 female connector to the serial port of the diagnostic tool or data logger. Secure the DB‑9 connector with its mounting screws if present to ensure a stable connection. Ensure the diagnostic equipment and vehicle ignition/power state meet the tool manufacturer's requirements before initiating communication or reading fault memory.

What to consider before purchase

• Confirm that your diagnostic device uses a DB‑9 serial port and accepts direct wiring from OBD‑2 signals
• Verify whether your application requires protocol conversion, active level shifting, or USB connectivity
• Check the required cable length and whether 1.15 m is sufficient for your setup

Recommendations

Use the cable for direct serial diagnostic connections and short‑range monitoring. If your device requires protocol translation or USB interfacing, select an active adapter or interface module designed for that purpose.
