User Guide
- Connect your laptop to the eithernet port of the Avalon
- Setup your laptop IP address 192.168.0.101
- Open http://192.168.0.100
- Make sure WR703N can access Internet, Configure WiFi: Network -> WIFI -> Scan(select your WIFI network) -> Join Network -> WPA passphrase -> Submit -> Save & Apply for connect to WIFI Internet
- setup your mining worker: Status -> Cgminer Configuration.
- Stop then Start the cgminer service (Restart not working. it's a known bug): System -> Startup,
- Check your avalon status: Status -> Cgminer Status
- Setup password/using ssh
ssh root@192.168.0.100 # Once you setup the password the telnet service will be stop. use ssh instead.
Cgminer option
--avalon-options 115200:24:10:45:282. this is the default avalon option. here is the details:
115200: the serial baud. this have to match the controller baud. 24: the miner count.(there are 3 modulars in avalon. each modular have 8 miners), if your avalon have 4 modulars. change it to 32 10: the chip count pre miner. 45: the controller timeout parameter. base on the chip clock. 50 for 256, 45 for 282. better don't touch those number unless you understand the whole protocol 282: the chip clock. the valid number: 256, 270, 282, 300.
Reflash TP-LINK TL-WR703N
System -> Backup / Flash Firmware -> Flash new firmware image (make sure Keep settings is checked), Avalon 703n images is here.

Connect to PC
Notice if you want to plug the USB to a computer instead of 703N, you must remove a Jumper on the controller board. the jumper's lable is P5, next to the USB port.
