IP Configuration
The AT-OME-ST31A is shipped with DHCP enabled. Once connected to a network, the DHCP
server (if available), will automatically assign an IP address to the unit. If the AT-OME-ST31A
is unable to detect a DHCP server within 15 seconds, then the unit will use a self-assigned IP
address within the range of 169.254.xxx.xxx.
Use an IP scanner, along with the MAC address on the bottom of the unit, to identify the unit on
the network. If a static IP address is desired, the unit can be switched to static IP mode.
The default static IP address is 192.168.1.254.

Press and hold the IP MODE button, on the rear of the unit, for approximately five seconds.
