Controls how markers are generated when using either the START button or a device connected through the Trigger Port. 

(First) Marker Number

Each marker is generated with a number which is stored as the transponder code in the passing record, this can be up to 7 digits

This is the first number used if Increase Marker Number is set to Yes. 

Increase Marker Number

If set to YES then the marker number used will increase with each subsequent marker set. 

Dead Time

Dead time sets the minimum time for which the system will wait before accepting a subsequent impulse in milliseconds (default 50ms).

This should only be necessary to adjust if your impulse device creates multiple successive impulses which may cause problems for timing. 

Trigger In

If using external inputs to create triggers then an offset can be subtracted from the time the impulse is received. This can be used to offset any delays in transmission of impulses from third-party devices.
