It is possible to plug a USB cable from a PC into the Avalon device and use the --avalon-options copying the command as used by the internal router used by the -Avalon. However since the Avalon code still currently uses the old serial usb -interface and is being rewritten to use direct USB, it is prudent to not be -dependent on this command long term, assuming it will go away. +Avalon. eg: + +--avalon-options 115200:24:10:45:282 + +The values are baud : miners : asic count : timeout : frequency. + +Baud: +The device is pretty much hard coded to emulate 115200 baud so you shouldn't +change this. + +Miners: +Most Avalons are 3 module devices, which come to 24 miners. 4 module devices +would use 32 here. + +Asic count: +Virtually all have 10, so don't change this. + +Timeout: +This is how long the device will work on a work item before accepting new work +to replace it. It should be changed according to the frequency (last setting). +It is possible to set this a little lower if you are trying to tune for short +block mining (eg p2pool) but much lower and the device will start creating +duplicate shares. + +Sample settings for different frequencies (last 2 values): +43:300 +45:282 +47:270 +50:256 + +Frequency: +This is the clock speed of the devices. Only specific values work, 256, 270, +282 (default) and 300. + +If you use the full curses based interface with Avalons you will get this +information: +AVA 0: 22/ 46C 60%/2400R + +The values are: +ambient temp / highest device temp set fan % / lowest detected fan RPM. + +Use the API for more detailed information than this. ---
