This unit was pulled from a working system that was upgraded and was in fine working order. We’ve included the DIN power supply, and although we erased the program and restored to factory defaults, with DHCP on, we decided to not update the firmware to the latest version being that the unit will probably be purchased by someone who is trying to keep an existing system working and rather than have you have to roll the firmware back, you can update it as needed to match your existing program.
