Product information

Description

The DeLOCK Loopback adapter RS-232/422/485 (model 66826) is a compact DB9 male connector tool for testing and troubleshooting serial communication lines. Designed for use with RS-232, RS-422 and RS-485 interfaces, it enables loopback testing to verify signal routing and basic data integrity during maintenance and diagnostics.

Advantages

The adapter is compact and lightweight with a durable metal-coloured housing, providing a simple plug-and-play solution for loopback tests. Its DB9 male connector fits standard serial ports and allows quick verification of transmit/receive wiring without additional cabling or complex setup.

Suitable for

  • Testing RS-232 serial ports on computers and industrial devices
  • Diagnosing RS-422 communication lines and differential interfaces
  • Verifying RS-485 networks and half-/full-duplex connections
  • Field troubleshooting by technicians and engineers

Key specifications

  • Connector: DB9 male
  • Supported interfaces: RS-232, RS-422, RS-485
  • Dimensions (W×D×H): 12.6 × 31 × 11.8 mm
  • Colour: Silver
  • Brand: DELOCK, MPN: 66826, EAN: 4043619668267

How to use

Insert the DB9 male connector into the serial port to perform loopback testing. Use appropriate terminal software or test equipment to send data and observe received signals; the adapter routes transmit lines back to receive lines for basic continuity and signal verification. Remove the adapter when testing is complete.

Usage recommendations

Use this loopback adapter for functional checks and basic diagnostics only; it does not replace protocol analyzers for in-depth traffic analysis. Ensure the device under test is powered and configured for the same interface standard (RS-232, RS-422 or RS-485) before connecting.
