access PDM’s GPIO system directly within a console, or at standalone nodes
anywhere on the network.
All this is carried over a single Ethernet cable, from PDM’s back panel to the closest
Livewire network switch. No additional PDM wiring is needed; in fact, Axia-equipped
PDMs don’t even have active analog or AES/EBU audio ports.
All controls, and most of the menus, are identical to PDM’s front panel. Operators won’t
have to learn anything new. Installation and setup is almost the same, with a few impor-
tant exceptions.
For that reason, read the rest of this manual first. Then use this section to understand
Livewire-specific setups.
If you have an analog | AES/EBU version of PDM and wish to convert it to run as a Live-
wire device, please contact the factory.
Network Setup
Since PDM-Livewire uses network connections instead of standard analog or digital
audio wiring, it won’t operate until it’s been properly configured for your network.
PDM’s output audio is broadcast to the network as a single
Livewire Source Channel,
identified by a number between 1 and 32,767. This number should be unique on your
network, and not be assigned to any other source channel.
PDM’s input is fed by specifying a
Livewire Destination Channel
number. This is the
Source Channel number of some other device on the network. It’s often the output of a
console, but it can be a network or remote, or any other signal source.
PDM’s Livewire GPIO system provides multiple sets of inputs and outputs, in four
groups of five i/o each. Each group is assigned a unique address.
•
Any of the 20 inputs can be assigned any Input function from PDM’s GPIO list
(page 27). The same function may be set to trigger from multiple inputs.
•
Any of the 20 outputs can carry any Output state from the GPIO list. A state
may be assigned to multiple outputs.
•
Inputs and outputs don’t have matching functions (that is, from the same row
on the list), or match their assignment in other groups. You are free to assign
them any way you want

.
•
PDM’s hardware GPIO is independent of Livewire. You can assign totally dif-
ferent functions from PDM’s front panel (page 27).
If you are controlling your network with
Pathfinder
routing and control software, you
have to register PDM in Pathfinder’s configuration controls. If Pathfinder doesn’t know

Axia has recommendations for using PDM’s GPIO with Element consoles, to make the operator experi-
ence as seamless as possible. Contact them for instructions.
