Product information

Description

The DeLOCK Loopback adapter RS-232/422/485 (model 66828) is a compact DB9 male connector designed for testing and troubleshooting serial communication lines. It supports RS-232, RS-422 and RS-485 interfaces and is intended for loopback tests, error analysis and data verification on serial ports. The adapter has a silver finish and small dimensions for easy storage and handling.

Advantages

The adapter provides a simple physical loopback solution compatible with multiple serial standards (RS-232/422/485). Its DB9 male connector allows direct connection to devices with a 9‑pin serial port without extra wiring. The compact size makes it convenient for field use and rack environments, and the silver housing offers basic mechanical protection.

Suitable for

  • Loopback testing of RS-232 devices
  • Testing and diagnostics of RS-422 and RS-485 lines
  • Error analysis and data verification on serial ports
  • Use by engineers and technicians during installation and maintenance

How to use

Attach the DB9 male connector of the loopback adapter to the device's 9‑pin serial port.

Observe transmitted and received signals or error counters in your test program to verify line functionality. Remove the adapter after testing is complete.

Usage recommendations

Use the adapter only on powered‑off or properly secured equipment when connecting or disconnecting to avoid accidental signalling. For accurate diagnostics, combine the physical loopback with appropriate software tools that monitor serial communication and error statistics.
