4 Software Configuration
INTRODUCTION
The following provides details on the software configuration of the NEXUS Series hardware. Please follow the
steps contained within this section for proper setup and configuration.
TOOLS REQUIRED
The following tools will be required for proper configuration of the system:
•PC/Laptop
•Ethernet cross-over cable, or other network connection to your NEXUS Series device
•Standard web-browser such as Windows Edge, Mozilla Firefox, Apple Safari, or other.
•NEXUS Series License filepre-installed
•24 V AC power source
CONNECTING TO A NEXUS SERIES DEVICE
The NEXUS Series device is shipped with a default IP address ( 192.168.1.251 ) and subnet mask ( 255.255.255.0 )
on the primary Ethernet Port. Your laptop’s network card must be configured in a manner where it may access
this IP network setting. Refer to your operating system documentation for details on how to configure your
network card.
See Ethernet Settings on page 30 for details on how to reconfigure NEXUS Series device IP Address.
Note: The secondary Ethernet Port (marked “Port D”) is configured with a default IP address ( 192.168.1.250 ) and
subnet mask ( 255.255.255.0 ), so that if connectivity is lost on the primary LAN port, you can use the secondary
port to gain access to the NEXUS Series controller as described below and reset it.
Primary and Recovery ports should not be both connected at the same time –unplug the primary port when
connecting your laptop to the recovery port.
To use the recovery port:
•Depending on your Operating System, set your Network Adaptor to the 192.168.1.0/24 IP network. e.g.
in Windows, in Settings > Network & Internet set the IP address to 192.168.1.1 and Subnet Mask to 255.255.255.0 (i.e.
the default value).
•You should now be able to reach http://192.168.1.250/ in a browser on your PC and proceed from
there. (If you have HTTPS enabled, you can reach the target at https://192.168.1.250/ instead.)
•Once recovery is complete, the NEXUS Series device must be rebooted.

PROJECT INSTANCES
Two instances are available within the NEXUS Series device. This provides the capability to host up to two
projects within the target. Each instance runs its own Aspect Control Engine allowing service to be performed
on separate instances. Within Instance 1 and Instance 2, the same options exist for the following:
•Calendar Configuration
•Users and Groups
•Mobile
•Instance Services
•Project Source
•Project Removal
•Aspect Control Engine Logs
•License Item Status
•Project Thread Status
CALENDAR CONFIGURATION
The Calendar Configuration area is used to configure iCalendar integration variables of the NEXUS Series
device. Within this section there are two pages:
•Calendar File
•Calendar User
Calendar File
Calendar File can be used to browse and modify what calendars have been previously published to the instance,
as well as allow users to manually upload iCalendar files (files with .ics extensions) to the device.
•To upload a saved calendar file, simply select the Browse/Choose File button and locate the iCalendar file
on your computer. Once located, click the Upload button.
•To delete a previously published calendar, place a check mark next to the corresponding file and select the
Delete button.

Calendar User
Calendar User provides the ability to change the default username and password credentials that are required
to allow iCalendar-based tools to publish data to the NEXUS Series device. By default, the username ( calendar )
and password ( user ) can be changed to any desired credential set. When referencing Calendars in Aspect
Studio, these credentials must be specified in order to properly access the file.
USERS AND GROUPS
Users and Groups are included within each instance in the NEXUS Series device. This provides the ability to
manage users in the Aspect control instance it serves.
