Property	Description
Is Device	Specifies whether the resource is a device. NI defines a device as 'a singular hardware product that monitors, measures, outputs, interprets or processes signals.' A resource can be both a device and chassis. In general, if the Serial Number property is not an empty string and a resource supports diagnostic functionality, this property is TRUE. Note that those features can exist without requiring this property to be TRUE. Note  Each device is not necessarily a separate field-replaceable unit. One controller or chassis may report multiple embedded devices if each resource has distinct configuration properties and information about how other devices connect to it. For example, an embedded PXI controller would return one resource for the controller itself, another for its GPIB controller (if present), and another for its Serial port (if present). See the table below for a detailed example.
Is Chassis	Specifies whether the resource is a chassis. A chassis has numbered slots and an enclosure that modules or devices plug into. A resource can be both a device and chassis. If this resource has only an external connector for a cable or accessory, this property will be FALSE. For example, for the resource corresponding to a GPIB controller or Serial port, this property will be FALSE because those devices are connected via an external cable. See the table below for a detailed example.
Service Type	Specifies the resource's type. Not all resources have a service. Valid values include: (0) NI Network Resource, (1) NI Real-Time, (2) NI System Configuration, (3) NI Web Interface, (4) Local System, (5) Local Net Interface, (6) Local Time Keeper, (7) Local Time Reference and (8) LXI Instrument.
Startup Settings:Disable FPGA Startup App	Specifies to disable any FPGA application the next time the target is restarted.
Startup Settings:User Directed Safe Mode	Specifies to boot into safe mode the next time the target is restarted. If you set this property to FALSE, the target may still boot into safe mode if an error occurred or there is no software installed.
Startup Settings:Enable Console Out	Specifies to enable the console output the next time the target is restarted.
Startup Settings:IP Reset	Specifies to reset the network configuration to the factory default the next time the target is restarted.
Startup Settings:Enable Secure Shell Server (sshd)	Specifies to enable sshd on the target. Starting sshd enables logins over SSH, an encrypted communication protocol. NI recommends setting a password for the controller before logging in over SSH or serial connection.
Startup Settings:Disable RT Startup App	Specifies to disable any LabVIEW startup application the next time the target is restarted.
Startup Settings:Enable UI Desktop Environment	Specifies to enable the desktop environment the next time the target is restarted.
