NOTE Controlling module selector input-to-output path
The configuration and the default I/O path of the module selector are set by using the
Module Selector tab screen of the Configuration window of the EasyEXPERT software.
The connection path from the input port to the output port is controlled by each test setup.
And the module selector switching status is indicated by the status indicator mounted on
the front panel. See Figure 2-6 and Table 2-6 for the indication and the connection path.

1. In the normal state, the module selector makes the path to the output port from the input port specified
by the Default field. When a measurement is performed, the module selector performs automatic
switching in every test. The selector makes the path to the output port from the module used for the test.
