AVALON DEVICES

Currently all known Avalon devices come with their own operating system and
a preinstalled version of cgminer as part of the flash firmware, based on the
most current cgminer version so no configuration should be necessary. It is
possible to plug a USB cable from a PC into the Avalon device and mine using
cgminer as per any other device. It will autodetect and hotplug using default
options. You can customise the avalon behaviour by using the avalon-options
command, and adjust its fan control-temperature relationship with avalon-temp.
By default the avalon will also cut off when its temperature reaches 60
degrees.

Avalon commands:

--avalon-auto Adjust avalon overclock frequency dynamically for best hashrate
--avalon-cutoff <arg> Set avalon overheat cut off temperature (default: 60)
--avalon-fan <arg> Set fanspeed percentage for avalon, single value or range (default: 20-100)
--avalon-freq <arg> Set frequency range for avalon-auto, single value or range
--avalon-options <arg> Set avalon options baud:miners:asic:timeout:freq
--avalon-temp <arg> Set avalon target temperature (default: 50)


Avalon auto will enable dynamic overclocking gradually increasing and
decreasing the frequency till the highest hashrate that keeps hardware errors
under 2% is achieved. This WILL run your avalon beyond its normal specification
so the usual warnings apply. When avalon-auto is enabled, the avalon-options
for frequency and timeout are used as the starting point only.

eg:
--avalon-fan 50
--avalon-fan 40-80

By default the avalon fans will be adjusted to maintain a target temperature
over a range from 20 to 100% fanspeed. avalon-fan allows you to limit the
range of fanspeeds to a single value or a range of values.

eg:
--avalon-freq 300-350

In combination with the avalon-auto command, the avalon-freq command allows you
to limit the range of frequencies which auto will adjust to.

eg:
--avalon-temp 55

This will adjust fanspeed to keep the temperature at or slightly below 55.
If you wish the fans to run at maximum speed, setting the target temperature
very low such as 0 will achieve this. This option can be added to the "More
options" entry in the web interface if you do not have a direct way of setting
it.

eg:
--avalon-cutoff 65

This will cut off the avalon should it get up to 65 degrees and will then
re-enable it when it gets to the target temperature as specified by avalon-temp.
