One computer runs it all

The server runs on a single computer. Choose a switcher, add cameras and assign inputs in the browser console. Changes take effect at once on every screen.

The Switcher page of the iTally console: TSL UMD V3.1 on a UDP port, with the inputs received and their cameras

11 switchers and protocols
Including vMix, Blackmagic Design ATEM, OBS Studio and TSL UMD.
One switcher at a time
Settings are saved for each switcher type, so you never set up twice.
Unknown is never Off
When iTally detects a lost connection or missing data, every screen shows yellow Unknown, never Off.
Read-only
iTally only subscribes and queries. It never sends switching or control commands.
Stays on your network
No internet, no account. Your data never leaves the venue.
Protected remote access
The console is local by default. To use it from another computer, turn on Other computers in the launcher and enter the access code.

Supported switchers

One at a time. iTally only subscribes and queries; it never sends switching or control commands.

Switcher	Models	Connection
vMix		Via TCP 8099 subscription; inputs bound by GUID, so reordering or renaming never shifts a camera
Blackmagic Design ATEM	Including multi-M/E models	Via UDP 9910; follows the M/E 1 program output, so cameras in nested M/Es, keys and SuperSource light too
OBS Studio	30 or later	Via obs-websocket 5.x; reads the visible sources in the program and preview scenes
TSL UMD V3.1 / V5.0	Pushed by the switcher	Via a UDP or TCP port this computer listens on; receives only, never sends
Datavideo DVIP	SE-650, SE-700, SE-1200MU, HS-1300	Via read-only queries of the PGM / PST buses
Panasonic AV-HS410	With the HS410_IF plug-in	Via TCP 60040, polling the PGM / PVW buses
Roland Smart Tally	V-60HD, V-160HD and others	Via HTTP queries of each channel's state
Roland VR Series	VR-50HD MK II and others	Via the LAN control port, TCP 8023; the protocol reports PGM only
Vizrt TriCaster		Via TCP 5951, receiving the Program / Preview the TriCaster pushes
Grass Valley	Kalypso, Zodiak, Ross Vision	Via the Contribution Tally protocol, pushed by the switcher to this computer

Over UDP, TSL UMD cannot detect a switcher going offline; see the docs. Each protocol follows the vendor's documentation and has been tested with simulated devices. On-site testing with real switchers is under way.

Get iTally

Install the server on one computer, then connect the screens you need. Every screen uses the same colours: red Program, green Preview, black Off, yellow Unknown.

Desktop: server and console

Reads the switcher, hosts the console and delivers tally to every screen. The launcher in the menu bar or system tray installs, starts and stops the service and can start it at login. Closing the browser or the launcher does not interrupt any screen.
