ProductSettings Description

ActiveMeasureAreaWidthInMeter

Width of the measuring area in which shots are calculated [m]

The active measuring area is the range in which the detection system should calculate and send shots to the AthleteMonitor.

The active measuring range is a rectangle, the width of which is defined with this parameter.

In the pictures below, the red rectangles are examples for active measurement areas of an open and a closed detection system:

CalibrationOffsetXInM

Device-specific X-coordinate calibration value [m]

Under construction

Device-specific horizontal correction value of calculated coordinates in meters. This setting is intended to correct target inaccuracies e.g. from inexactly mounted target pictures. This value is usually determined by measuring the deviation of multiple calibration shots.

Remark: The correction is always horizontal and a positive value is a correction to the right, independent of other settings like MountingFlipXZ or MountingRotZInDegree.

Example: value = 0.01

A shot with coordinates (X: 0.045 m / Y: -0.2 m) will be corrected and counted as (X: 0.055 m / Y: -0.2 m).
This value should be used when the target picture is mounted 1 cm right of the nominal position.

Default value: 0

 

CalibrationOffsetYInM

Device-specific Y-coordinate calibration value [m]

Under construction

Device-specific vertical correction value of calculated coordinates in meters. This setting is intended to correct target inaccuracies e.g. from inexactly mounted target pictures. This value is usually determined by measuring the deviation of multiple calibration shots.

Remark: The correction is always horizontal and a positive value is a correction to the right, independent of other settings like MountingFlipXZ or MountingRotZInDegree.

Example: value = 0.01

A shot with coordinates (X: 0.045 m / Y: -0.2 m) will be corrected and counted as (X: 0.045 m / Y: -0.19 m).
This value should be used when the target picture is mounted 1 cm above the nominal position.

Default value: 0

 

InternalRefTranslatXInM

Default value: 0

 

InternalRefTranslatYInM

MaxCadence

Sets the device into maximum cadence mode to support higher rates of fire

When activating this mode, the use of Shotsensors for crossfire detection is no longer supported!

During normal operation, the coordinates are calculated after the shot, which takes a maximum of 50 ms. Therefore, the system cannot detect faster than 1200 shots per minute. (For some products the maximum rate of fire is even lower, due to other reasons – see table below)

In “MaxCadence” mode, raw data is stored in a buffer for max. 40 shots. As soon as no shot is registered for 0.5 seconds, the shots are calculated and the system is inactive for several seconds.

See the table below for maximum accessible rates of fire.

Device	Maximum Rate of Fire (Normal Mode)	Maximum Rate of Fire (MaxCadence Mode)
ACB01	1200 RPM (50ms)	1875 RPM (32ms)
ACB02	1200 RPM (50ms)	1875 RPM (32ms)
ACB03	1200 RPM (50ms)	1875 RPM (32ms)
ACE01	1200 RPM (50ms)	2400 RPM (25ms)
ACF01	180 RPM (333ms)	1875 RPM (32ms)
S101G3	180 RPM (333ms)	1875 RPM (32ms)

MountingFlipXZ

Specifies whether the target is mounted back-side-front

Not supported for AcousticEye

This setting must be set when the target is mounted back-side-front (e.g. behind the wall). In this case the X-coordinates must be mirrored around the measurement system’s reference point (e.g. center for AousticBar)

Example: value = 1

A shot’s coordinates (X: 0.045 m / Y: -0.2 m) will be corrected to (X: 0.055 m / Y: +0.2 m) because the bullet hits the measurement system from its back side.

Device	Default Value
ACB01	0
ACB02	0
ACB03	0
ACE01	Not supported
ACF01	0

 

MountingRefKind

Specifies the targets used reference point for mounting target pictures

Depending on which kind of target picture has to be mounted on the measurement system, this setting has to be set accordingly:

To mount a target picture with a center reference, the measurement system must be set to MountingRefKind = CenterReference.

To mount a target picture with an edge reference, the measurement system must be set to MountingRefKind = EdgeReference

Device	Default Value
ACB01	Center Reference
ACB02	Center Reference
ACB03	Center Reference
ACE01	Edge Reference
ACF01	Center Reference
S101G3	Center Reference

MountingRotZInDegree

Reflects the mounting type of the target (e.g. roof) as an angel [°]

In the event that the measuring system is mounted rotated (e.g. wall or roof), the mounting angle (in degree) must be applied to this setting to ensure that the coordinates are calculated correctly.

Examples:

Default: 0

 

OverrideMicAmplification

Override the used microphone amplification

If a value other than “Inactive” is selected, the microphone gain is set to the corresponding value.

Default is Inactive

SaTriggeredInternally

Trigger SignalAnalyzer internally instead of from TimeDifferenceRecorder (SaChannelThreshold)

 

Default: false

SaChannelThreshold

Threshold when SignalAnalyzer internally triggered (50 ≙ 1V)

 

Setting only applies when SaTriggeredInternally set true, otherwise SignalAnalyzer is always triggered from TimeDifferenceRecorder.

SaConversionSpeed

SignalAnalyzer’s conversion speed divider value for calculating sampling frequency

 

The set value is a register value, which is a divider that can be used to derive the sampling frequency from the clock frequency.

 

Default value: 8 (≙500 kS/s @ 50 MHz clock frequency)

SaPreMeasurements

Number of recorded measurements before trigger by SignalAnalyzer

 

Device	Default Value
ACB01	32
ACB02	32
ACB03	32
ACE01	32
ACF01	128
S101G3	128

SaMeasurements

Total number of recorded measurements by SignalAnalyzer (including SaPreMeasurements)

 

When MaxCadence mode is active, the maximum supported value is 64.

 

Device	Default Value
ACB01	64
ACB02	64
ACB03	64
ACE01	64
ACF01	256
S101G3	256

TdrCounterOverflow

TimeDifferenceRecorder’s overflow value for channels which do not trigger

 

Device	Default Value
ACB01	650000 (≈ 2.23m)
ACB02	650000 (≈ 2.23m)
ACB03	650000 (≈ 2.23m)
ACE01	650000 (≈ 2.23m)
ACF01	650000 (≈ 2.23m)
S101G3	650000 (≈ 2.23m)

OverrideMicTrigger

Override the used microphone voltage threshold to trigger shot detections

If a value other than 0 is set, the trigger levels are calculated based on this setting.

The two TriggerLevels are: 2.5V +- OverrideMicTrigger

Default is 0

 

SettlingDelayInMilliseconds

Prevents the target from detecting shots for the specified duration after a shot [ms]

After a shot is detected, the measuring system ignores any sensor signals for the next specified delay time. Any shot within this delay time will not be detected.

This setting can be useful if shots can cause unwanted interference signals, such as noise or objects flying through the measurement system (e.g. caused by a bad bullet catcher or walls reflecting shot noise in an indoor shooting range).

The maximum shot cadence will be reduced when increasing this setting.

Examples:

0 = deactivated: detect new shots as fast as possible

100 = 100 ms delay time / maximum shot cadence of 10 shots per second / 600 shots per minute.

Device	Default Value [ms]	Maximum Rate of Fire (Normal Mode)	Maximum Rate of Fire (MaxCadence Mode)
ACB01	25	1200 RPM (50ms)	1875 RPM (32ms)
ACB02	25	1200 RPM (50ms)	1875 RPM (32ms)
ACB03	25	1200 RPM (50ms)	1875 RPM (32ms)
ACE01	45	1200 RPM (50ms)	2400 RPM (25ms)
ACF01	300	180 RPM (333ms)	1875 RPM (32ms)
S101G3	300	180 RPM (333ms)	1875 RPM (32ms)

 

ShotThemeliaLifetimeInS

How long shots remain stored on the server [s]

Detected shots, including their raw data, are stored on a server in the rack to allow later reconstruction of an incident. After the specified time, shots will be permanently removed from the server.

Example: value = 604800

Registered shots will be permanently removed from the server after 7 days
