3.2 Starting the instrument console
The instrument console is a software application that provides a way to configure settings,
monitor performance, run diagnostic tests, and maintain the system and its modules. It replaces
the keypads and small-screen displays traditionally found on the front of system modules. The
instrument console functions independently of data applications and does not recognize or control
them.
