Tally (Roxanne): Difference between revisions

The power connector is fairly obvious, anything doing more than about 7V should suffice, the 12V ones (cameras inc. Skycam) will do perfectly and it has an internal regulator. Maximum is around 24V - DO NOT use [[Howard]]'s power supply. The RJ-45 connector goes to a length of Cat-5 cable running to the splitter in the studio, and the male DB-9 connector (like a monitor connector) goes to the GPI port on [[Magic DaVE]]. This has a slightly special cable, it's shown in the picture, but is a purple cable with a block plug on one end and a yellow on the other, should be easy to spot. Finally the female DB-9 connector can be run to a PC for serial communication. This means even when vision mixer input channels are reassigned and moved around on account of have 5 or more sources, the correct brick lights up when a camera is mixed to.

At power-on, the system should default to each vision mixer input channel, 1-4 mapping to tally channels 1-4. A computer can connect using a serial link at 9600 baud to the control unit. Using [[YVP_Protocol|YVP Protocol]] the computer can remap which vision mixer input each tally output follows. Ideally, this should be handled by the software controlling the mux that feeds the vision mixer, so that when a command is sent to the mux to assign a camera to a vision mixer channel, the corresponding command also goes to the tally system. At the time of writing, the only known example of this is the OB Director Control software used for Woodstock 2012, which might be in the Software drive, and is definitely in the YSTV Git repository. The software running on the control unit microcontroller is also with this OB Director software.
