Table 10. ThinOS system variables (continued)
Variable Description
$SN Serial number or Service tag
$VN Version number
Right($xx, i) or and Left($xx, i) Specifies that the variable is to be read from left or right. The $xx is any of above
parameters and the parameter i specifies the digits for the offset of right or left.
Relationship between INI and Wyse Management
Suite group based configurations
This section describes the relationship between INI file parameter–based configurations, and Wyse Management Suite group
based configurations. Both INI files and Wyse Management Suite configuration processes have similar functionality. However,
the implementation differs. Understanding this concept should greatly reduce the number of redundant configurations and help
migrating devices from a file server with INI files to Wyse Management Suite.

Configuration ThinOS 8.6 with INI ThinOS 9.1 with Wyse
Management Suite
Global configurations applied at boot to all clients—When
using Wyse Management Suite, client configuration policies
that applies to all devices should be defined using a Wyse
Management Suite Device Policy Parent Group. This is similar
to wnos.ini configurations when using a file Server.

Device Policy Parent Group
Configurations applied at boot to a group of clients—When
using Wyse Management Suite, client configuration policies that
apply to a group of device should be defined using Wyse
Management Suite Device Policy Child Groups. This is similar
to an INCLUDE file statement with part of a system variable
that enables more than one client device to obtain the defined
configurations. The advantage of Wyse Management Suite is
that it enables multiple Child Group levels, hence allowing
nesting of configurations.

Device Policy Child Groups
Configurations applied at boot to a single client device
—When using Wyse Management Suite, client configuration
policies that apply to a specific device can be completed using
Wyse Management Suite Device Exceptions. This is similar to an
INCLUDE file statement using a full system variable that allows
only the selected client to obtain the defined configurations.
NOTE: Device exceptions must be used when required
and should be kept to a minimal number of configurations.
Excessive use of Device Exceptions or Device Exception
configurations can affect performance and manageability.

Device configurations dynamically selected from the
ThinOS Login menu—The Select Group feature in ThinOS
enables you to dynamically select and load configurations and
is often used to access multiple virtual environments. In Wyse
Management Suite 2.0, this feature is supported only on ThinOS
9 devices.
The Select Group feature can be enabled under Wyse
Management Suite PRO Groups & Configs Device Policy
Group when creating a Parent Group. Select Group feature
is not supported by Wyse Management Suite Device Policy Child
Groups.
