INLINE 4 and INLINE 5 Hardware

What should I do if my INLINE 4 or INLINE 5 adapter's power light is off?

This indicates that the adapter is probably not receiving power. Verify that the data link cable is securely connected to both the adapter and the data link connector and that there are no bent pins in the connectors.

What does it mean if the power light of my INLINE 4 or INLINE 5 adapter is blinking on and off?

This indicates that the adapter's power voltage is out of its normal operating range. Change or adjust the power source so that the voltage is in the normal 8 V to 50 V range.

What does it mean if one of the communication port lights is blinking on and off slowly?

This indicates that the adapter is transmitting messages over the communication port, but is not receiving any messages in return. When the adapter is properly communicating over a port, the associated light should blink on and off rapidly. Make sure your computer or data link is connected and working properly.

What should I do if all the adapter lights stay on continuously?

This indicates that the adapter has experienced a failure or the memory was corrupted while trying to download new firmware to the adapter. Try removing power and reapplying it, waiting for several seconds to see if the adapter resumes normal operation. If it doesn't, try downloading the latest software, carefully following instructions on the INLINE 4 software download web page or the INLINE 5 software download web page. If this also fails to work and the adapter is still under warranty, contact your authorized Cummins distributor.
