The PAx is a microprocessor based
multi-input, multi-output, audio and announcement controller.
The integrated 16x16 audio switch matrix is capable of switching any of sixteen
inputs to any of 16 outputs.
Multiple inputs and outputs can be used
concurrently or in a multi-zone broadcast manner.
|PAx Multi-Zone Audio and
The PAx can switch 16 audio inputs to 16 audio outputs, with multiple
paths in use simultaneously.
A typical passenger terminal or station installation consists of a single PAx providing
multi-zone paging and ADA compliant visual messaging. Supporting interfaces would be local
control microphones, telephone interface for remote paging access, pre-recorded messaging
for repeat announcement or automated information, one or more amplifiers per zone, and
Visual Message Signs for ADA compliance.
- Interoperability Controller:
The PAx has optional interface cards for Radio, Dial-up telephone, and direct circuit
connection. Utilizing the 16x16 audio matrix on the backplane, radio-radio,
radio-office, radio-telephone connections can be setup from the field. In addition, by adding a
Control Console communicating to the PAx via Ethernet, the PAx becomes a the core of a dispatching
- Onboard Transit Vehicle:
A typical onboard vehicle
installation consists of a single PAx unit, an operatorís microphone, one
or more vehicle microphones, one or more emergency phones,
amplifiers, speakers, and Visual Display Signs. The PAx can automatically generate
pre-recorded audio and visual station stop messages based on contact closure
inputs or data
received via the onboard Ethernet or serial channels. Manually initiated pre-recorded
arrival and departure messages can be generated from a keypad or terminal on the
operators control panel.
- Remote Control Paging and Visual Messaging:
Audio input switching
may be controlled remotely via the PAxís onboard 10BaseT Ethernet port
or one of the three configurable asynchronous serial channels. The
remote application sends a command to the PAx to connect an input(s) to
an output(s). The PAx confirms the action by sending the
appropriate data response. When the remote message is delivered, it will
be heard over the selected zone(s). Likewise, the PAx can digitally
receive a remote message for display on local ADA compliant Variable
- Features Continued
- Priority Management:
To prevent announcement collisions or contention, each PAx audio input is configured with
a priority assignment. If more than one input attempts to announce over the same output,
the PAx prevents talk over by switching only the input with the highest
priority to the output zone(s).
- Supervisory Control of Audio Components:
Using onboard Ethernet, serial communications, and I/O, the PAx can communicate directly
with several manufacturers' audio, video and control components to provide remote
supervision, device management, announcement verification, and error reporting. The PAx
will interrogate the devices and report all relevant or pre-configured data to the remote
- Local and Remote PAx Configuration Management:
Communicator software installed in a laptop or computer, connected
through the PAx primary serial port or the Ethernet allows local
configuration of the PAx.
- Remote Configuration Management:
The PAx can be re-configured and altered remotely via Ethernet or
serial port using the PAx Communicator software or a control system application that uses the PAx
software application interface commands (API). This allows the altering of priorities,
volume settings, and default parameters of the PAx as required for the location.
- Integrated Passenger Information System:
Multiple PAx Controllers can be integrated into a complete multi-terminal, multi-station
Passenger Information System by using Pentas WavWriter Suite of PIS applications or
through 3rd Party Control applications taking advantage of the PAxs easy to use API
and data command interface. (Contact Penta for information and documentation on the PAx
- The PAx occupies only 2 units of rack-space and consumes less than
20 Watts of power.
