The AT-HDR-CAT-4ED 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-HDR-CAT-4ED
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/16
. If this occurs, refer to the AT-HDR-CAT-4ED
User Manual for more information.
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.
IP Configuration
Switching the IP mode using the Front Panel
1. Make sure the AT-HDR-CAT-4ED is powered.
2. Connect an Ethernet cable between the LAN port of the AT-HDR-CAT-4ED and the Local
Area Network (LAN).
3. Press and hold the POWER button for approximately 15 seconds. Release the POWER
button once all the front-panel LED indicators begin to flash. The number of flashes will
indicate the currently selected IP mode. Refer to the table, below.
