Blackmagicdesign ATEM Production Studio 4K Installation And Operation Manual page 172

If you want to choose a different static IP address, you can set it to anything you like
that's in the same range as the ATEM switcher, so long as it's not already in use by
another device on your network. Default IP addresses for ATEM products are best
avoided for this reason, including: 192.168.10.1, 192.168.10.2, 192.168.10.3, 192.168.10.10,
192.168.10.50 and 192.168.10.240.
If your ATEM switcher connects via an existing Ethernet network switch, you may wish
to choose "Configure Address Using DHCP" as this setting automatically obtains the IP
Address, Subnet Mask and Gateway information from your DHCP server.
5 Type in the IP address of your ATEM switcher in the "Switcher Address" field. Your
ATEM switcher defaults to a fixed IP address of 192.168.10.240 when shipped and this is
the number you should type in this field unless you have changed it.
6 "Set tally outputs" should be set to "Switcher Inputs 1-8" unless you are configuring
a second unit to provide tally outputs for switcher inputs 9-16 of an ATEM 2 M/E
Production Switcher.
7 Click "Apply". The white LED to the right of the USB port should stop flashing and
remain on to indicate it has successfully found the ATEM switcher. The GPI and Tally
Interface is now ready.
8 Close Blackmagic ATEM Setup and disconnect your USB cable.
