The AT-JUNO-451 is shipped with DHCP enabled. Once connected to a network, the DHCP server (if available),
will automatically assign an IP address to the unit. Use an IP scanner, along with the MAC address on the back of
the unit, to identify both the unit and its IP address on the network. If a static IP address is desired, the unit can be
switched to static IP mode. Use one of the following procedures to switch between DHCP and static IP mode.
The default static IP address of the AT-JUNO-451 is 192.168.1.254.
If the AT-JUNO-451 is unable to detect a DHCP server within 15 seconds, then the unit will set all IP settings to zero.
Setting the IP Mode
1. Make sure the AT-JUNO-451 is powered.
2. Connect an Ethernet cable between the LAN port of the AT-JUNO-451 and the Local Area Network (LAN).
