Product Detail

This professional OBD2 16-pin to 4-port DB9 splitter cable is an essential tool for advanced automotive workshops and telematics testing. It is engineered to expand a single OBD2 diagnostic port into four separate DB9 female RS232 connections, allowing technicians to run multiple diagnostic analyzers, CAN bus monitors, ECU tuners, or data loggers simultaneously without the need to constantly swap cables.

Accurate Specifications & Features:

  • Connectors: 1x Standard 16-Pin OBD2 Male connector + 4x Standard DB9 Female RS232 connectors (with thumb screws for secure attachment) .
  • Cable Design: Features a smart central connector lock that secures the four branches, preventing tangling and providing long-term durability.
  • Cable Length: 3 Meters (approx. 9.8 ft), offering ample slack to route the cable from the vehicle's OBD2 port to a comfortable workstation .
  • Cable Protection: Each branch is fitted with durable heat-shrink tubing at the Y-splits for reinforced protection against wear and tear.
  • Conductivity: Uses high-grade pure copper cores to ensure stable, high-speed data transmission and reliable serial communication.

Key Benefits & Applications:

  • Simultaneous Data Analysis: Connect up to 4 devices (such as oscilloscopes, protocol analyzers, and VCI units) to a single vehicle port.
  • Non-Destructive Installation: Provides an easy way to expand diagnostic capabilities without splicing or modifying the vehicle's original wiring.
  • Professional Use: Perfect for complex ECU reprogramming, CAN bus monitoring, and multi-device testing in automotive labs or workshops.
