Firmware Installation & Update

TALLY-NODE firmware is installed and updated via a USB-C cable and the web flasher. For the detailed flashing procedure, follow the Firmware Installation page. This document covers the overview, simultaneous both-end update precautions, factory reset, and troubleshooting.

Firmware Overview & Version#

Item	Value
Current firmware version	3.0.0 (may vary depending on development state)
Wire Protocol version	v12 (must match on both Master and Receiver)
Flash method	USB-C web flasher (OTA not supported)

How to check the version#

Device	Where to check
Master	OLED boot screen page / Web UI Dashboard (see Web UI Guide)
Receiver	OLED boot screen page (see Receiver Operation)

Version match required

The Master and Receiver must run the same firmware version. If versions differ (especially the Wire Protocol), they cannot communicate.

Firmware flash (web flasher)#

Prerequisites#

A USB-C cable that supports data communication (charge-only cables will not work)
A PC (with a browser supported by the flash guide page installed)
The device ON/OFF switch set to ON

Browser permission

The browser must be able to access the device (serial port). Use the browser recommended on the guide page.

Firmware flash procedure#

1
Connect USB-C
Connect the PC and device with a USB-C cable
2
Open the guide page
tally-node.com/flash firmware installation page
3
Select the device role
Select the firmware matching the device role (Master / Receiver)
4
Run the flash
Follow the guide; the browser recognizes the device and runs the flash
5
Reboot
When the completion message appears, reboot the device

Caution during flashing

Do not unplug the USB-C cable until flashing completes. Interrupting it may corrupt the firmware.
Do not operate the device ON/OFF switch during flashing.

Device unresponsive symptom

If a problem during flashing leaves the device unresponsive, press the front button and the reboot button to enter download mode.
You can then flash the firmware again using the web flasher.

Post-flash verification#

Verify the OLED boot progress reaches the end (Master 12 steps / Receiver 8 steps)
Verify the version updated on the Web UI Dashboard or OLED System Info

Simultaneous both-end update (key precaution)#

The most important rule

The Master and Receiver firmware versions (especially the Wire Protocol) must match for communication to work. Updating only one side will stop tally from working.

Update checklist#

Prepare both the Master and Receiver
Flash both ends to the same firmware version
Verify both ends boot normally (OLED progress completes)
Verify the Receiver is recognized in the Master Web UI Devices (see Web UI Guide)

Update procedure#

1
Flash the Master firmware
Follow the flash procedure above
2
Flash the Receiver firmware
Follow the same procedure, selecting the Receiver firmware
3
Verify reboot on both ends
After both reboot, verify they boot normally
4
Check the Devices page
Verify the Receiver shows Online on the Master Web UI Devices page
5
Verify tally display
Verify the tally display works normally (see Receiver Operation)

Version mismatch symptoms#

Symptom	Cause
Receiver does not receive (RSSI normal but tally not working)	Master firmware version ≠ Receiver

Solution: re-flash both ends to the same version (see Troubleshooting)

Factory Reset#

Factory Reset method#

Factory Reset is only available from the Master Web UI.

1
Click the Factory Reset button
Click the Factory Reset button at the bottom of the Master Web UI sidebar (see Web UI Guide)
2
Confirm
Approve in the confirmation dialog
3
Reboot
All settings are reset and the Master reboots

Scope of impact#

Device	Impact
Master	All settings (network/switcher/RF/license key) reset, then reboot
Receiver	No impact — the Receiver's own NVS (camera_id, brightness, off-mode) is retained

The RESET button is NOT a factory reset

The bottom RESET button only reboots and retains settings. For a factory reset, always use the Web UI.

Reconfigure after Factory Reset#

Network Connection — reconnect to the Master Web UI
Switcher Integration — reconnect ATEM/vMix/OBS/OSEE
Reactivate the license — re-enter the license key

Troubleshooting#

Flash failure#

Symptom	Cause	Solution
Browser does not recognize the device	Charge-only cable	Replace with a USB-C cable that supports data
Browser does not recognize the device	Port/driver issue	Try a different USB port and the recommended browser
Flash interrupted/failed	Poor cable contact	Replace cable/port and retry
Repeated auto-reboot after boot	Corrupt firmware	Re-flash the firmware

Boot log check (advanced)#

To analyze boot problems, you can check boot messages over a USB-C serial connection. See the boot diagnostics in Troubleshooting.

Version mismatch resolution#

If a version mismatch warning appears in the Web UI, re-flash both ends to the same version. (See Simultaneous both-end update.)
