TallyCCU Pro
TallyCCU Pro is an open-source hardware/software solution that enables full CCU (Camera Control Unit) control of Blackmagic Design cameras via SDI, along with tally light integration with vMix.
This Companion module connects to the TallyCCU Pro Arduino device over your local network, allowing you to control up to 8 Blackmagic cameras directly from your Companion buttons.
| Setting | Description |
|---|---|
| IP Address | The IP address of your TallyCCU Pro device (e.g., 192.168.1.100) |
| Default Camera | Camera ID (1-8) used when no specific camera is selected |
Full control of all Blackmagic CCU parameters organized by category:
Each parameter has actions for:
The module provides feedbacks for button style changes:
| Feedback | Description |
|---|---|
| Connection Status | Green when connected to TallyCCU Pro |
| Active Preset | Highlights when specific preset is active |
| OIS Enabled | Shows OIS state |
| Phantom Power | Shows phantom power state |
| Dynamic Range Mode | Matches specific dynamic range mode |
| Parameter Value Compare | Match any parameter to a specific value |
| Parameter Above Threshold | Trigger when parameter exceeds threshold |
The module provides variables for use in button text:
| Variable | Description |
|---|---|
cam[1-8]_active_preset_name | Active preset name for each camera |
cam[1-8]_active_preset_id | Active preset ID for each camera |
cam[1-8]_preset[0-4]_name | Name of each preset slot |
cam[1-8]_param_[key] | Current value of any parameter |
The module maintains a persistent TCP connection (port 8098) with TallyCCU Pro for real-time bidirectional synchronization. Changes made via the web interface or other clients are automatically reflected in Companion variables and feedbacks.
| Issue | Solution |
|---|---|
| "Connection error" | Check IP address and network connectivity |
| Parameters not updating | Verify TallyCCU Pro firmware is V3.0+ |
| Tally not working | Check vMix IP configuration in TallyCCU Pro web interface |
