3.3 FRONT PANEL

The front panel of the EM405D contains two openings for access to the M-modules’ front panel connections and three LED indicators as shown in Figure 6. As mandated by the M-module specification, each M-module should provide a front panel connector containing the M-module I/O signals. The two openings on the EM405D’s front panel provide access to these connectors. The functions of the three front-panel LED indicators are:

PWR: indicates that power is supplied to the module and that the power switch is ON. The units should be operating normally.

A, B: indicates that M-module A or B is currently being accessed. The LED will illuminate temporarily each time the module is accessed by the host software.
