Description

How to use

Connect the loopback adapter to the device's DB9 serial port. For loopback testing, ensure the adapter pins match the interface standard in use (RS-232, RS-422 or RS-485) and perform the desired transmission tests or diagnostics using your terminal or test software.

Usage recommendations

Use the adapter on powered-down equipment when possible to avoid transient signals during insertion. Verify pinouts for the specific serial standard before testing and store the adapter in a dry environment to prevent corrosion.
