HDfury Diva macros: RS232 commands sent to your projector automatically
Macros let the Diva talk to your display for you. When the incoming signal changes, the Diva sends the RS232 commands you have chosen, so a projector switches to the right picture mode without anyone reaching for a remote.
A projector usually needs a different setup for different content. HDR10 wants one gamma and one lens memory, SDR BT.709 wants another, 3D wants something else again. Doing that by hand every time the disc or the streaming app changes is exactly the sort of job people give up on. The Diva already knows what is arriving, because it is decoding the infoframes and metadata to route and scale the signal, so it is in the right position to tell the display what to do about it.
Where it came from
The feature was built for and by the JVC projector owners community. Working with power users, HDfury developed a set of automatic and custom macros for JVC projectors, and the detailed instructions for that setup are posted by the community rather than reproduced in the manual.
Not only JVC
The Diva now allows each command to be edited individually, which is what takes the feature beyond one brand. If your display accepts RS232 commands, you can put its own command strings into the fields and the Diva will send those instead. What is sent is entirely up to you; the Diva only decides when to send it, based on the incoming signal type or a particular metadata value.
That covers the situations people usually automate: content arriving as 3D, as HDR10, as SDR BT.709, as SDR BT.2020, and more besides. Decide which RS232 command should go to the display for each of those, enable the ones you want, and the rest happens on its own.
Before you start
Get the serial link working first. Connect the supplied RS232 jack cable to the display as described on the jack connections page, then use the RS232 test tool in the CEC and RS232 section to send a single command by hand. When the display responds to a command you typed, it will respond to one the Diva sends on your behalf. The baud rate you set in that section, 19200 by default, is the one the macros use.
