Installing the NIO CommKit Host Interface

Running the dkdiag Diagnostic Test

The dkdiag program provides a series of hardware diagnostic tests that ver-

ify that the Datakit interface board is installed correctly. You can use the

dkdiag program in either local or remote loopback mode.

If the Datakit interface board is connected to the CPM-HS module, use the

remote loopback mode. Use the local loopback mode when the Datakit inter-

face board is not connected to a CPM-HS board in the VCS. Local loopback

mode is recommended for the most accurate diagnostic results.

The dkdiag program is located in the /opt/dk/sbin directory.
