Voice Communications (Voice Comms) is a real-time audio communication feature that allows you to talk with other users connected to the same vehicle. Whether you’re coordinating between multiple operators, communicating with remote technicians, or managing a team during testing, voice comms provides clear, direct communication with built-in priority management.
Encrypted and secure voice transmission
Real-time voice calls with other connected users
Automatic speaker management - System intelligently prioritizes speakers
Push-to-Talk (PTT) mode - Control when you transmit using a keyboard shortcut
Text Communications is a real-time messaging feature that lets you communicate with other users who are connected to the same vehicle or session. Whether you’re using the desktop application or accessing the web interface, you can send and receive messages instantly.
Send and receive messages in real-time with other connected users
Automatic alerts/Quick Messages - Send quick messages automatically triggered by system events
Triggers - The display can be configured to act on certain text message commands.
View message history - See the last messages exchanged in your session
Multiple connection options - Access the feature via desktop app or web browser

Setup - ED7/ED7M/ED10M
Authentication
In Display Studio, the first thing to configure is the authentication settings, found in File → Telemetry Credentials.
Setting
Description
Region
Select the region closest to you for lower latency
Vehicle Name
Exact vehicle name entered during the activation step above
Password
The same password entered during the activation step above
Use SSL
Must be set to true when using official Emtron servers
Validate SSL Certificate
Optional: Verifies server authenticity.
Battery Backup Required for SSL Certificate Validation
If the device is wired without a battery backup, it will lose its system clock on every power cycle. An incorrect system time will cause SSL certificate validation to fail, and the device will be unable to connect to the telemetry server.
To avoid this, either:
Wire the device with a battery backup to preserve the system clock, or
Disable Validate SSL Certificate (reduces security but allows connection without a valid clock)
Ensure to click Save Telemetry Settings as these are stored independently of the config.
PC Client — EmStream
On the PC, use EmStream to subscribe to the live telemetry stream, monitor channels, and use voice and text chat. See the Getting Started guide for connection steps.
Telemetry Provider is the standard operating mode for most applications and is the subject of this help topic.
Telemetry Consumer is for advanced usage and should be DISABLED for a standard telemetry setup.
Setup: ED7/ED7M/ED10M
Assuming you have an active telemetry license and the authentication settings configured in Display Studio, you can now configure the telemetry function.
Settings
Telemetry data settings can be accessed from the main menu: Functions → Telemetry. Ensure the Telemetry Provider tab is selected.

Channel Configuration
Allocate channels you want to be sent in the appropriate group
Best practice: Only include channels you actually monitor. Unnecessary channels waste bandwidth.
Once configured, ‘Write’ the config.

Priority System
How It Works
The voice server manages multiple speakers using a priority system:
Your priority number is set in Voice Settings (0 = highest, 10 = lowest)
When multiple people try to speak:
Lower number = gets to speak first
Higher number = gets interrupted by lower numbers
System automatically manages silence between speakers
Practical Examples
Scenario 1: Small team (1-2 people)
Priority system is relaxed
Everyone can speak simultaneously
Useful for open discussion between two people
Scenario 2: Three or more people connected (3+ people)
Race Engineer (Priority 0) - Always gets to speak first
Driver (Priority 1) - Can speak if engineer is not speaking.
Technician (Priority 4) - Speaks only if both driver and engineer are silent
Priority system becomes strict
Only one person speaks at a time (based on priority)
Higher priority users can interrupt lower priority users
Prevents audio chaos in crowded rooms
Setting Your Priority
Use Case Guidelines:
