getfaults

This command gets the status of the mute, over temperature and pll loss of lock.

For mute, “0” indicates the unit is in an unmuted state. A “1” indicates a muted state. Note that a “1”
does not necessarily indicate an error as the unit could have been commanded into a mute state (see
“setmute” command).

For over temp and pll, a value of “0” means no error and a value of “1” indicates an error.

Figure 2-5: Command getfaults

resetfaults

This command clears faults under certain conditions. Note that the “mute” fault code indicates muted
state, not necessarily an error. Since the unit can be commanded into mute state, without a fault, the
“resetfaults” command will not clear a mute fault in this situation.

The temperature sensor has a trip point (above which a fault is triggered) and a reset point (below which
a fault is automatically cleared.) The reset point is set below the trip point to provide hysteresis. See

Table 2-2

for Trip and Reset Points.

The resetfaults command will clear an overtemp fault which has been tripped if the unit is currently below
the trip point. If the fault mode sensor value is above the trip point, the fault cannot be cleared. Some
faults may not have a reset point, and must be reset through the “resetfaults” command.
