13.3.2 Troubleshooting data issues
The other type of problem that can occur in the system is when data is not
flowing properly between the program software, the circuit cards, and the
attached panels and interfaces. A troubleshooting sequence in this situation
would be to first check cabling, then reset the card or panel, then reset the
entire system.
13.3.2.1 Analog port card (MVX-A16) Reset button
Resetting the analog port interface causes the configuration information for the
interface and its attached devices to reload to the interface from the CPU
card’s operational memory (located in its microprocessor’s RAM), thus clearing
up any corruption of data that may have occurred in the analog port interface
microprocessor. The interface and all connected panels and interfaces
momentarily stop their current activity and restart. The reset button must be
pressed for more than two seconds to take effect.
If the entire system is operating except for one analog port interface, or one or
more panels connected to the interface, press the reset button for that
interface only.
This button is slightly recessed from the front panel to prevent it from being
accidentally pressed. A tool such as a bent paper clip is required to press this
button.
13.3.2.2 CPU card Reset button
When the CPU card is reset by pressing its reset button, the card’s non-volatile
memory reloads all configuration information to the card’s microprocessor.
Resetting the card clears any corruption of data in the card’s microprocessor.
The card momentarily stops its current activity and restarts. The same system
configuration that was active before the card was reset will be active after the
reset.
The reset button is slightly recessed from the front panel to prevent it from
being accidentally pressed. A tool such as a bent paper clip is required to press
this button.
13.3.2.3 CPU card Full Reset button
Press and hold the full-reset button and simultaneously press the reset button
for the system to perform a cold restart. All cards in the matrix reset
regardless of any system preferences in the program software. All audio
devices connected to the cards, such as panels and interfaces, reset as well.
When the cards and connected audio devices reset, they momentarily stop
their current activity and restart. During this process configuration information
