Example: An Activity Timer
The repeater and each receiver input has an activity timer available to cause a
macro to be triggered after activity on the repeater has ceased. But,
sometimes one activity timer is not enough. A
User Timer can be used to
implement one or more additional activity timers.
Three macros will be required to implement the activity timer: one is triggered
when the repeater is activated by a receiver, a second is triggered when all
receivers are inactive, and a third is triggered when the timer times out. Our
example triggers a macro that speaks a message, but any commands can be
executed at that time.
For this example, we’ll create macros 8711, 8712, and 8713. We’ll use timer
#8.
First, setup the timer and assign the macros.
; Setup
(PW) 49 08 03 3000 * ; Set Timer 300.0 seconds
(PW) 49 08 02 8713 * ; Set Timer Macro
(PW) 26 11 8711 *
; Set Any-Rx-Active Macro
(PW) 26 09 8712 * ; Set All-Rx-Inactive Macro
Enter the macro that is triggered when any receiver is active. This macro stops
the timer.
; Macro: Any-Rx-Active: Stop Timer
(PW) 20 8711 (PW) 49 08 00 *
; stop timer
Enter the macro that is triggered when all receivers are inactive. This macro
starts the timer.
; Macro: All-Rx-Inactive
(PW) 20 8712 (PW) 49 08 01 *
; start timer
Enter the macro that is triggered when the timer times out. This macro can
perform any operation, but in our example it speaks a message.
; Macro: Timer Timeout, speak 1-second-pause + “Net”
