Strobe LED
Strobe Number and Interval
There are two parameters available for configuring the Apollo-X
’s flasher
; the interval and the
pulse count. At default settings, the Apollo-X
’s LED will flash twice every
fifteen seconds, each
LED pulse lasts for 50 milliseconds.
Note:
The strobe command will impact LED operation for all timer modes simultaneously,
except low battery mode
. To configure the strobe to run while in that mode, the
$timer
command with the
STB
task must be used.
The interval setting determines the number of seconds between flashes, while the pulse count
determines the number of pulses with each flash. Both parameters are set using the following
command:
$strobe
[number of pulses]
[interval in seconds]
The number of pulses can be up to 4, while the period is limited to a maximum 60 seconds. The
number of flashes is consistent between all timer modes and would also be implemented for
Low Battery mode. This command is written as:
$strobe
X
Y
Example
Command
Pulse Number
Strobe Interval
1
$strobe
1
20
2
$strobe
2
50
Sending the commands in Example 1 would set the flasher to pulse once every twenty seconds.
Example 2 would set the flasher to pulse two times every fifty seconds. The device responds
with the new setting when commanded.
Strobe Disabling
Some users may prefer to disable the Apollo-X
’s strobe regardless of environment. To disable
the regular operation of the strobe, issue the following command:
$switch B 0
To re-enable the strobe, issue:
$switch B 1
With this feature, the strobe will not pulse according to its settings according to the
$strobe
command. The strobe will only illuminate if the magnetic reed switch is acted upon, as the LED
is the visual aid used to indi
cate the Apollo’s power status.
Using the $switch method to disable the strobe is saved in memory. This means the strobe will
remain in a disabled state through resets unless commanded otherwise.
