Default Factory Wired Ethernet Configuration
- Modifying the Settings -
AirAura requires
two
IP addresses – one serves the main DSP board and the
other serves the microcontroller that operates the front panel. Ethernet was used
for the DSP to front panel communications interface because of its speed over,
for instance, a serial connection, a tremendous benefit when calculating and
displaying the high resolution graphics required by the AirAura’s front panel.
The AirAura is configured at the factory to the following:
Main DSP board IP address
192.168.1.200
Front panel controller IP address 192.168.1.201
Gateway
192.168.1.1
Subnet
Mask
255.255.255.0
Changing the AirAura’s wired Ethernet interface is a simple process; however
two considerations must be kept in mind when doing so.
1. The Main DSP board and the front panel
must
be on the same network
subnet. In other words, if the Main DSP board has been assigned an IP
address of 109.16.77.200, then the front panel must also have an IP
address assigned to it that is in the range
between
109.16.77.1 and
109.16.77.254 in order to enable communications between them.
2. The two rear panel RJ-45 connectors share the wired side of the wireless
interface which is connected to the same internal Ethernet switch as the
Main DSP board and the front panel. Therefore, if the Main DSP board
and front panel IP addresses are changed, the wired side of the wireless
interface must also be reconfigured in order for wireless to work. Please
see
Appendix D
for the procedure for reconfiguring the wireless interface.
Changing AirAura’s Network Configuration
To change the IP address and network configuration of the AirAura’s Main DSP
board and front panel interface the features built into the front panel may be
used. Using the front panel trackpad place the cursor in the lower left quadrant of
the left display. Then using the rightmost illuminated “V” button, click the button
to bring up the View/Hardware dialog.
