CREATING MACROS • MACRO EXAMPLES
7 Beaver Brook Road, Littleton, MA 01460 • 978-486-0086 • www.burk.com
Self-Directed Startup
This example shows some more of the
versatility of the macro language. Here, a
status channel triggered Macro #10 to run.
The macro first tests to find out if the
REMOTE/LOCAL button on the front panel
is in LOCAL mode. If it is, the macro ends
immediately.
If the unit is in REMOTE mode, then the
macro proceeds. The unit MUTES the
status channel that starts the macro.
Meter Channel 1 is then turned off along
with the muting of Meter Channels 2, 3,
and 4. The Calibration Constants of Meter
Channels 2, 3, and 4 are adjusted for the
new power output levels of the backup
transmitter. The displayed value viewed by
monitoring software of Meter Channel 1 is
equated to the product of Meter Channels
5 and 6.
Since other macros could have made
changes to various meter or status input
channels, Status Channel 4 and Meter
Channel 10 are tested to make sure they
are active or unmuted. Then Macro #20 on
this unit is started, which is the full power-
up routine. This macro waits 2 minutes for
Macro #20 to finish. Status Channel 3 is
unmuted. An alarm is generated, notifying
the dial-out connections and any full-time
direct connect stations that the backup
transmitter is now going on-air. A capture
is made to show the current state of all
inputs and outputs for database use as
needed. Just in case any other macros
dealing with the backup transmitter are
running, they are terminated to stop any
interference. The macro then ends
normally.
