9. Configuration Web Page
9.1. Description
The P139-HD has two levels of configuration:
At the factory each unit is set up to the customers’ specific hardware configuration: Number of headsets
and radio ports in use, intercom setup, number and type of control panels and function of each control
and PTT keyline.
In the field, users may adjust volume levels and features of each enabled radio and headset port through
a Configuration Web Page in the unit. The Configuration Web Page is accessed by connecting a laptop to
the audio router via the Ethernet port, J6. No special software is required and the web page should work
with most recent web browsers.
9.2. Network Requirements
The P139-HD acts as a DHCP server at address 192.168.0.1. The laptop being connected must be set
up that it receives its IP address via DHCP (i.e. not a static IP address) and must not be connected to
another network e.g. via WiFi.
The Configuration Web Page supports Internet Explorer 6 and higher, Firefox 2 and higher, Safari and
Opera.
NOTE: The web server in the P139-HD may take about 5 seconds to open each page. In most web
browsers, there will be a progress indicator in the address bar or status bar showing the page is loading.
Only refresh the page or click on the menu to change pages if the loading indicator shows that the page
failed, or it will start the process over and take longer.
9.3. Accessing the Web Page
The web page is stored on the MMC card inserted into J7. If the MMC card is not inserted, the audio
system will run normally, but the web page will not be available.
NOTE: Do not insert or remove the MMC card or Ethernet cable while the Audio
System is powered up.
To start the web server running on the Audio System:
1. Power down the audio system.
2. Ensure the MMC card is inserted fully into J7 in the correct orientation (label side towards the D-
50 connectors)
3. Connect a laptop to J6 via the Ethernet cable. The laptop must be powered on and booted before
connecting to J6.
4. Power on the audio system. The audio system will detect the MMC card and Ethernet connection
and start booting the web server. If either of these is not present the audio system will go into
normal mode and the A LED will start flashing within 15 seconds of power up.
5. After about 5 minutes, the A LED will start flashing and the audio system will be operating as
normal. Due to the extra load of running the web page, both the flashing of the LED and the
response of the control panels will be slower than normal.
6. Open a web browser and enter the address http://192.168.0.1. After a few seconds the
Configuration Web Page will load and display the System Status screen.
On the P139-HD (T) audio system, the Ethernet port is J8 and the MMC card slot is J9. See Table 3.
