IP Configuration
1. Make sure the AT-OME-MH21 is powered
2. Press and hold the
IP MODE
button, on the rear of the unit, for approximately five seconds.
The AT-OME-MH21 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-MH21
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
.
