25-Seven Program Delay Manager Version 2.3 Manual April 2013 55
If you want to control it from a computer or dumb terminal, you’ll need a DB-25 null
modem or a cable that reverses pins 2 and 3 (data), pins 4 and 5 (flow control). Since
PDM uses standard pin configurations, you should be able to use an easily available
DB-25 to DB-9 adapter to connect more common 9 pin cables.
RS-232 can be used either for control, or to delay data. In the case of delays, data gets
sent on the same RS-232 connector as it’s received, so if you have one device generating
data and another one listening, you’ll need a
Y
cable to split the TX and RX signals.
RS-485
There are also two independent RS-485 differential data lines on this connector. Each is
independently controlled and programmable as input, output, or bi-directional.

Axia / Livewire setup
Introduction
PDM’s optional Livewire version lets you connect your profanity delay system directly
to a Livewire network. Once configured, you can:
••
Feed PDM with any signal available on your system
••
Send its full-quality output to any available input (or multiple inputs at the
same time)
••
Control PDM directly from selected Axia consoles
