+= Ephiphan Broadcaster operation
+== Settings
+The best working settings depended on hardware generation, see [[hardware:epiphan-broadcaster]]
+The Admin-UI can be accessed by appending /admin to the URL (ie http://grabber3/admin).
+Login is in the Keepass.
+== Operational notes
+Some projector setups require a custom resolution on the Broadcaster configuration to work properly.
+Typical howto:
+ * Generate a EDID file by connecting the mixer laptop (or another linux box) to the projector and run make-edid.pl.
+ * cat/copy output to file on a machine with an web browser (currently not the mixer laptops, due to florolf ;-)
+ * open http://grabberX.lan.c3voc.de/admin/
+ * goto framegrabber settings
+ * upload edid file via upload form
+ * After replacing the EDID file, the Broadcaster does not need to be restarted. Dis- and reconnecting the cable from the computer's display port is sufficient.
+ * If you see "Cannot update EDID. Please verify integrity and authenticity of the EDID file. E1011-3", this is usually resolved by dis- and reconnecting the cable leading towards the projector.
+How to get a EDID file:
+ * Preferred way: Script by Florolf that will create EDID files for the projector/display connected at a given machine: https://github.com/voc/scripts/blob/master/vgabroadcaster/make-edid.pl
+If you want to force a special resolution, or subset of resolutions (e.g. prefer 16:9, no 16:10 only fallback 4:3)
+ * http://www.epiphan.com/support/vgadvi-broadcaster-drivers-documentation/ -> Downloads -> EDID
+   * see also https://github.com/voc/scripts/tree/master/vgabroadcaster/edid-files
+ * FIXME how to allow multiple resolutions at once? Concatenate EDID Files?
+   * Rumor has it https://ez.analog.com/docs/DOC-2143 will make it work. Otherwise, request the required data from Ephipan support via the support chat on their website {{hardware:edid:customedid_16-9.edid}}
+   * mithro of timvideos pointed us towards http://edid.tv/ und https://github.com/timvideos/edid.tv/tree/master/edid_parser.
+Framegrabber settings: The Web admin interface contains most of the information that you need to make image adjustments including a brief description of the effect of each adjustment and the adjustment range.
+To make an adjustment, add a value to one or more fields and select Apply.
+**To clear any adjustments, delete the value from one or more fields and select Apply. To have changes take effect, you must reboot the VGA Broadcaster Lite device.** You can make more than one change before selecting Apply and rebooting.

+The broadcasters are available via 192.168.255.250, no matter which IP is configured on the web interface. To reach it, set up your computer with IP address 192.168.255.249 using 255.255.255.252 as netmask.

+The integrated 4 GB USB stick fits 3-4 hours of video at 1280x720 (H264, incl. Audio). The broadcaster can be configured such that it doesn't record anything if there is no input signal (VGA/DVI).
