Primary Device Functions (continued)
Low Signal Quality Threshold
The threshold value for low signal quality can be set in
order to monitor the current signal quality. It is displayed as
a value between 0 and 100 in percent. If the current signal
quality value drops below the signal quality threshold value,
the Low signal quality level warning is output.
The function can be deactivated by setting the threshold
value to zero.
Current Signal Quality
The current signal quality is displayed as a value between
0 and 100 in percent. If no valid signal quality is available,
the value is set to 255.
Signal Quality Bad
The status of the signal quality is displayed as a Boolean
value. If the value is TRUE, the signal quality is below the
threshold value; if the value is FALSE, the signal quality is
equal to or greater than the threshold value. This status is
visualized by an orange LED that illuminates if the value is
TRUE.

5.10.5 System Commands
Command Device Action
Value
0x81 (129) Application Reset – Sets the threshold
value with ISDU index 0xCE Low Signal
Quality Threshold to default 0. The
feature is thereby deactivated and the
evaluation of index 0xCF subindex 2
always results in FALSE.
0x82 (130) Restore Factory Settings – Sets the
threshold value with ISDU index 0xCE
Low Signal Quality Threshold to default
0. The feature is thereby deactivated
and the evaluation of index 0xCF
subindex 2 always results in FALSE.
