We're using two etherants:
- etherant G on the profile tower
- connected to hub in profile data system
- serves profile, downwind1 and pressure1 data systems
- etherant G on the downwind tower # 10
- connected to hub in downwind2
- serves downwind2, upwind and pressure2
Currently seeing about 25 dB of signal from both antennas. signal -65 dBm, noise -90 dBm.
These etherants are served from wlan2-Ext-Ant on the AP24.

To prevent the AP24 from serving addresses to the vipers, I entered these commands:
ip dhcp-server lease add mac-address 00:80:66:10:43:96 block-access=yes add mac-address 00:80:66:10:43:8C block-access=yes add mac-address 00:80:66:10:43:92 block-access=yes add mac-address 00:80:66:10:43:8D block-access=yes add mac-address 00:80:66:10:43:C5 block-access=yes add mac-address 00:80:66:10:42:A6 block-access=yes add mac-address 00:80:66:10:43:96 block-access=yes
We have 6 pocketecs for local storage. (Originally we had 8, one died, and one is at Marshall I believe)
Let's use the pocketecs for the 4 sonic adams.
The pressure adams will generate about 290 Mbyte/day (24 bytes/sample, 10 samples/sec, 14 channels). So for the pressure systems, let's use 4 Gbyte usb pen drives.
6/4/08 Adams up and running for checkout.
One of the power supplies running 3 adams died. It suffered from thermal shutdown and dropped its output to 4vdc killing the adams. It's rating is 12Ain and was operating in the wind tunnel: not encouraging given prospects in central valley. After letting it cool, we restarted and measured the following currents and measured the profile adam running on a second supply:

We put a 3rd supply to split the larger load.
