Following the directions very closely to update the firmware in our FA50 due to the rollover issue. Network is correctly configured, IP of both the PC and FA50 are correct, and I can ping the FA50 from the PC. All that said, the install batch program hangs on the display of “>>my IPaddress=172.31.1.1” and proceeds no further. I’ve tried a dozen variations of running the .BAT with the power of the FA50 off (it waits for the IP address so the .EXE seems to be working), to with it on, to running the .BAT in administrator mode. This is on a PC with latest Windows. Could it be a firewall issue? Please advise, and thanks as our AIS xmit is inop.
