Don't Update firmware while on DHCP

      Please do not do firmware update while the unit and the computer are in DHCP mode, especially if you connect directly between the computer and the Dugan unit.

      The problem is that the firmware update process requires rebooting of the unit. Once rebooted, the unit needs to wait for the DHCP server to issue IP address. If the DHCP server is slow to hand out IP, or the DHCP server hands out a new IP address, the Utility program would be confused and thinks that the unit is no longer on the network. The situation is made worse if you connect the computer directly to the Dugan unit. It that case, there is no DHCP server. When the unit reboots, the computer would lose Ethernet connection momentary. It would then proceed to go through the APIPA (autoIP) process to get a new IP in the range of 169.254.x.x. Same for the dugan unit. The APIPA process usually takes many seconds to complete.

       

      We have received multiple user reports saying that their unit no longer pass audio after they updated the firmware, especially with firmware update to 1.08 and beyond. The Utility would show the unit with “FW V1.09, FP V25.5” or something similar. If you see either FW or FP being 0.00 or 25.5, that means some firmware components were not updated correctly. Please check the “Firmware Update Revision Notes.pdf” for the correct FW and FP versions for your unit.

       

      Thanks.
