Ok.
After changing the MXE3300 IPs, I set static IP for iPhone that work good. But ipconsol 5550, doesn't answer. I set it's IP static and register successfully, when run 5550 program, it try to configuring keypad, but can't. I connect the keypad straight to MXE LAN port, but it's LED is solid.
It try to configuring keypad.
The firewall is off, anti virus is unistal.
