DeviceMaster Software Developer Kit Troubleshooting

Review the following information before calling Technical Support because they will request that you perform many of the procedures or verifications before they will be able to help you diagnose a problem.

The following checklist may help you diagnose your problem:

  • Verify that you are using the correct types of cables on the correct connectors and that all cables are connected securely. See the DeviceMaster Installation and Configuration Guide for up-to-date cabling information.


    Most customer problems reported to Pepperl+Fuchs Comtrol, Inc. Technical Support are eventually traced to cabling or network problems.

  • Make sure that you have updated the DeviceMaster with the latest Bootloader version.

  • Make sure that the serial device settings have been selected in the NS-Link driver, and if necessary, the DeviceMaster Server Configuration web page to match the serial device that you are connecting to the port.

  • If you have a spare DeviceMaster try replacing the DeviceMaster.

For additional troubleshooting, you can refer to the Pepperl+Fuchs Comtrol, Inc. forum or contact Pepperl+Fuchs Comtrol, Inc. Technical Support . You may want to refer to the SDK Customer Support Policy before calling Technical Support for assistance beyond SDK installation.
