Node Pro is TelemetryOS's dedicated digital signage hardware platform. For complete hardware specifications and features, see What is Node Pro?

Hardware Architecture

System Components

Node Pro includes the main computing unit, power supply, HDMI/USB-C connectivity cable, and VESA-compatible mounting hardware. Installation configurations include VESA bracket mounting, behind-screen placement, and surface mounting.

Display Connectivity

The platform features dual HDMI ports and a USB-C port with DisplayPort alternate mode for multi-display configurations:

Port	Resolution	Use Case
HDMI 1 (Primary)	4K @ 60fps	Main display, video walls
HDMI 2 (Secondary)	4K @ 60fps	Dual-screen, extended displays
USB-C DisplayPort	4K @ 60fps	Modern displays, daisy-chaining

Each port supports 4K content playback independently, allowing single-device operation of complex display arrangements including video walls, dual-screen presentations, and multi-zone content delivery.

📘
Multi-display configurations utilize the secondary HDMI port and USB-C DisplayPort output. The device drives 4K resolution across all connected displays simultaneously, supporting coordinated content presentation across multiple screens.

Power and Peripheral Architecture

The device operates on standard AC power (100-240V, 50-60Hz) through the included adapter:

Power specifications:

Input: 100-240V AC, 50-60Hz
Output: 12V DC
Typical consumption: 15-25W
Peak consumption: 35W

Configuration Interface

Node Pro includes an onboard settings interface for network configuration, display parameters, and device-specific customization:

Configuration categories:

Network: WiFi, Ethernet, static IP, proxy settings
Display: Resolution, orientation, scaling, overscan
Audio: Output selection, volume, testing
System: Time zone, device name, updates

The settings interface remains accessible throughout device operation for configuration adjustments and troubleshooting.

Network connectivity:

Ethernet: Immediate connectivity (DHCP automatic, static IP optional)
WiFi: Credential configuration required through settings interface

Device-to-Account Linking

Pairing Architecture

Node Pro supports two account linking methods:

Method	Process	Use Case
Code Pairing	Enter 6-digit code in dashboard	Testing, small deployments (< 10 devices)
Provisioning Tokens	USB token pre-configuration	Bulk deployments (10+ devices), zero-touch setup

Each device generates a unique 6-digit pairing code accessible through the onboard interface:

Code pairing workflow:

Device displays 6-digit code after network connection
Enter code in TelemetryOS console (Devices > Add Device > Pairing Code)
Device registers to account
Playlist assignment and content delivery begins

📘
Provisioning represents the recommended deployment method for Node Pro at scale. Provisioning tokens enable automated device-to-account linking with offline resilience, particularly valuable for deployments of 10 or more devices. Code-based pairing serves testing environments and small-scale deployments where manual claiming is acceptable.

Fleet Management Integration

TelemetryOS console manages device registration through device serial numbers (found on packaging labels):

Registration process:

Device serial number entry in console
Organization hierarchy assignment (location, group)
Targeted content deployment configuration
Bulk device management enablement

Organization hierarchy supports:

Location-based grouping (building, floor, room)
Department/function categorization
Content targeting and filtering
Bulk configuration updates

TelemetryOS Console Management

Device Profile Configuration

Device profiles define operational parameters:

Setting Category	Configuration Options	Purpose
Screen Orientation	Landscape, portrait, 90°/180°/270° rotation	Display mounting alignment
Display Resolution	Auto-detect, manual override	Content scaling and clarity
Time Zone	Geographic location-based	Scheduling accuracy
Content Schedules	Time-of-day, day-of-week rules	Content presentation timing

Profile settings apply immediately upon synchronization between console and device (typically within 30 seconds for connected devices).

Display and Audio Configuration

Display Parameter Management

Display configuration encompasses resolution management, orientation adjustment, and pixel scaling:

Display Setting	Options	Impact
Resolution	Auto-detect, manual selection (up to 4K)	Content clarity and performance
Orientation	0°, 90°, 180°, 270°	Physical mounting alignment
Scaling	100%-200%	Text legibility and content sizing
Overscan	Enabled/Disabled	Edge content visibility

Resolution auto-detection matches display capabilities automatically. Manual override supports specific deployment requirements (custom resolutions, video walls).

Console interface verifies display settings through live preview capabilities and remote configuration adjustment without physical device access.

Audio Output Architecture

Audio routing supports both HDMI digital audio and 3.5mm analog connections:

Output Type	Characteristics	Use Case
HDMI Audio	Digital audio through display	Standard installations, display speakers
3.5mm Analog	Stereo analog output	External speakers, audio distribution

Audio configuration:

Volume control (0-100%)
Output selection (HDMI or analog)
Audio testing (test tones for verification)

Content with audio tracks plays automatically when audio output is configured.

Deployment Architecture

Reliability and Testing Considerations

Enterprise deployments benefit from validation testing before production rollout:

Testing checklist:

Test Type	Duration	Validation
24-hour stress test	24 hours continuous	Stability under sustained operation
Network resilience	Multiple connectivity interruptions	Recovery from network failures
Content playback	All media formats and playlists	Rendering correctness
Temperature monitoring	Full operational cycle	Adequate cooling in installation environment

Extended operational testing identifies potential stability issues, network configuration problems, or content rendering challenges under real-world conditions.

Fleet Monitoring Capabilities

TelemetryOS console health monitoring:

Monitoring Category	Metrics Tracked	Alert Capabilities
Uptime	Device online status, reboot history	Offline device notifications
Content Delivery	Playlist synchronization status	Sync failure alerts
System Health	CPU temperature, storage capacity	Threshold-based warnings
Network Status	Connection type, signal strength, bandwidth	Connectivity issue detection

Alert configuration supports proactive notification through:

Email notifications
