Select COR Pulse-Triggered Macro
Select Pulse Parameters
Selects macro to be executed when a user keys the microphone
PTT button several times in succession.
Sets required characteristics of received pulses.
The controller can execute a macro when a user keys his microphone PTT
button several times in succession. Two commands are used to set up this
feature: One command selects the macro to be executed, and the other sets
the parameters of the pulse string. For the Select COR Pulse-Triggered Macro
command:
• Macro Name is the macro to be executed.
• The macro will be executed on the falling edge of the last pulse.
• The macro will not be executed if any Pulse Parameters are not met.
Three variables affect the setting of Pulse Parameters:
• Pulse Count is the number of pulses that occur within the Minimum
Duration and Window Time parameters to trigger execution of the macro.
The range is 0 to 9 pulses.
• Minimum Duration (sometimes called Width) is the required duration of a
pulse, measured in 10mS counts. The range is 0001 to 9999 counts, or
00.01 (10mS) to 99.99 seconds. By requiring a certain minimum duration,
the controller can discriminate against narrow noise pulses. Use four digits.
• Window Time (sometimes called Window) is the overall time allowed for all
the pulses to be counted and is measured in 10mS increments. The range
is 0001 to 9999 counts, or 00.01 (10mS) to 99.99 seconds. Use four digits.
