50 25-Seven Program Delay Manager Version 2.3 Manual April 2013
Two drop down menus lets you choose the stream inputs.
••
Select
Disabled
,
RS-232 port
,
Local network port 5445
(for Stream A) or
5446
(for Stream B) or
Remote Machine
.
••
If you’ve selected
Remote machine
, supply the IP address and port number of
that machine in the
address
field below.
Outputs have the same choices, except they use
Local network port 5447
for Stream A
and
5448
for Stream B.
If you choose
RS-232 port
for delayed data, remember that it’s bi-directional. Data will
be sent on the same RS-232 connector as it’s received: if you have one device generating
data and another one listening, you’ll need a
Y
cable to split the TX and RX signals. This
also applies if you’ve set RS-232 for data.
RS-232 can support only one function at a time. If you choose it for a data stream input,
don’t enable it for the other data stream’s input… unless you want to carry the same
data to different outputs. And if you’re using it for a data stream, don’t enable it for re-
mote control.
Installation
PDM fits a standard 19" equipment rack, 1 unit high by 12" deep (allow additional
depth for the connectors).
While PDM doesn’t generate much heat, we recommend at least one unit of blank or
perforated rack panel separating it from any heat-generating devices above or below it.
Do not block the fan or intake vents on the rear of the unit.
••
You can check PDM’s internal temperature using front panel menus (page 30),
or via web interface (page 43). As a general guideline, PDM should be within
20° Fahrenheit (about 7° C) of ambient room temperature
••
PDM’s cooling fan is its only moving part, and must move freely to keep PDM
in normal operating range. If temperature readings appear high, check the fan
and air intake vent immediately.
••
We recommend you check the cooling fan annually, to make sure it’s moving
freely and that dust hasn’t built up.
The internal power supply will self-adapt to any voltage between 100 – 240 v 50/60 Hz.
It consumes 1.8 A maximum; typical draw is about 32 watt @ 120VAC.
We recommend that PDM be connected to a UPS (uninterruptible power supply), to
prevent loss of audio in case of a power disruption. This is good advice for any mission-
critical electrical device.
XLR versions of PDM are normally fed by the Program output of a talk studio. Their
output gets sent to the air chain, master control, or network as appropriate. The talent
and producer should listen to the console’s Program output, rather than the delayed
