1.3 Powering Up The Device

This device is not equipped with a power switch and is simply connected to the power supply adapter which is
plugged into a suitable AC power source, to power it up.
Once the device is powered it goes through the following startup sequence:

•

Reset switch is checked and if it is pressed then the

Software failsafe recovery procedure

is entered.

•

Routing matrix is initialized to Preset 0 state (defaults to source 1 connected to all destinations).

•

The button control panel is initialized and buttons are illuminated to show the initial routing status.

1.4 Front Panel Button Interface

The MSC-XDM2000L is equipped with a 32x32 button panel which provides one of several options for
controlling and viewing the status of the routing matrix.
This panel interface provides separate input and output buttons. One output button is active at a time, indicated
by it being lit. The current connection status for the active output is indicated by the relevant numbered input
button being lit. Pressing an input button will cause that input to be connected to the current active output.
