Once the LED stop this fast flashing (about 5 minutes) power off cycle encoder 5. remove USB 6. power on 7. go to 192.168.0.171 8. Local S/W version Antrica.340.01(2019.09.02-11:37:14) 9. for decoder repeat steps 1 thru' 6. In step 2 no adaptor is required 10. go to 192.168.0.172 11. Local S/W version Antrica.340.01(2019.09.02-11:37:14)
