25-Seven Program Delay Manager Version 2.3 Manual April 2013 29
† — There are multiple outputs for some PDM functions:
••
If an output setting ends with
Trig
, PDM generates a single 250 ms output
pulse when that state is reached. This can be handy for interfacing with auto-
mation systems.
••
If an output setting ends with
Lamp
, PDM’s GPIO output mimics the front
panel button’s lamp. It stays low when the lamp is on, high when the lamp is
off, and cycles when the lamp is flashing. This can be handy for building cus-
tom remotes for talent and producers.
••
Building
,
Exiting
,
DelayFull
,
DumpReady
,
DelayEmpty
, and
Muted
indicate PDM’s current operational state, and are held low for as long as these
states exist.
••
DumpReady
indicates when the Dump Size (page 20) has been reached, and a
single dump is now possible. It can be connected to your phone system or
console to absolutely block incoming calls until they are safe.
••
DelayFull
can be used to tell talent or producers that the maximum delay has
been reached. In most setups, this will mean that multiple or extended dumps are
also possible.
¶ — “Cue” and “Flag” let you automatically delay the signals from satellites,
automation systems, and producers’ control panels. This keeps the signals in
sync with appropriate program audio at all times.
Connect this kind of contact closure or logic pulse to any PDM GPIO input that
you’ve designated as a
Cue
or
Flag
: when a signal is received, it’s linked to the
incoming audio sample. It stays with this sample, no matter how much time ma-
nipulation is being applied. You can then pass the mark to other devices by as-
signing an appropriate GPIO output.
Cues and Flags usually indicate important programming events such as com-
mercials or news breakaways. PDM preserves their timing as much as possible,
even if the audio that originally carried them has been dumped.
If you dump audio that contained a Cue or Flag, PDM will send the appropriate
signal during the “splice” between older and newer material in its output stream.
••
Cue marks generate a 250 ms trigger when they’re reached.
••
For example, if the network provides a contact closure when it’s time for a local
break, connect it to an input that has
Cue1
assigned. No matter how much delay is
applied, PDM will generate a
Cue1
output when that sample is reached… which
you can use to trigger other equipment to play the break.
••
Flag marks record a continuous logic input. Their output reflects that logic
state when the appropriate audio sample reaches PDM’s output.
••
For example, you can use a Flag to activate a skimmer or logging recorder.
Connect a mic’s tally signal to the input, and use its output to keep the recorder
on whenever the mic is on the air… regardless of how much delay is in use.
