Plus-X IIU Installation Guide Rev B

Network Settings
Each Plus-X IIU must be assigned a static IP address for communication with the ARC Plus
remote control system. However, using a dynamic IP address assigned by Dynamic Host
Configuration Protocol (DHCP) is an easy way to do initial setup of the Plus-X IIU. This
document describes the procedure for establishing initial communications with a Plus-X IIU in a
network that supports DHCP and in a network that does not.
The table below lists the firmware version in which DHCP functionality was introduced for the
Plus-X IIU. The table also specifies the default hostname that must be used for initial connection
to the Plus-X IIU when it is installed on a network that supports DHCP.

Initial Connection Using DHCP
Connect the Plus-X IIU to your LAN and apply power. If this is the first power-up for a new unit
or the first network connection after execution of a master-initialization, the Plus-X IIU will issue
a DHCP request for an IP address. If the network supports DHCP functionality, a dynamic IP
address will be assigned to the unit. To access the unit, launch a web browser and enter the
h
ostname from the table above in the browser’s address field, followed by the forward-slash
symbol as follows: PLUSXIIU/
The login screen shown below will be displayed.
Select and confirm a password for the admin account and click the Save button.
Note: If the page above is not displayed or the browser indicates that the page cannot be found, it is
possible the connected network does not support DHCP. In this case follow the steps outlined in
“Initial Connection Without DHCP”. Otherwise,
log in as shown below and
continue to “Set a Static IP
Address”.
