(Please note that additional product specific troubleshooting information may be included in the Frequently Asked Questions (FAQ) section of the individual product pages on this website.)

Power your iPhone OFF and then ON again. (Do not simply put the iPhone to sleep. Power it completely OFF and then ON.)

If the problem continues to exist…

Confirm that your iPhone detects the cable:

If the iPhone IS detecting the cable:

Check whatever app you are using to make sure that it is configured properly. Check with the app developer if you have questions about the proper configuration.

If you are using a Serial Cable, Console Cable or DEX Cable the issue may be that the communication settings (baud rate, parity, etc.) are not properly configured in the app that you are using. If you are using an Ethernet product confirm that an IP address is assigned. In the case of the L2-NET or L4-NETP this will be done in the app that is making use of the ethernet connection. Communicating with certain ethernet devices may require use of a static IP address. In the case of the L6-NETPOE, L6-NETAC or L5-NET the IP address is configured using the Settings app.

If the iPhone IS NOT detecting the cable:
