Pro GenII sled tally system

[Tim Smith]

I just purchased a Pro GenII sled that has the cramped attic HD-SDI upgrade. I am trying to figure out a way to come up with a tally system through the sled. I have the one HD feed via bnc and the analog feed that was already there for program. Is there any of the power ports that are on the top stage that I could use for a tally system? If so, any ideas on how to do this? I know someone that has been using a Pro GenII has come up with a way to do this by now. I appreciate any input and ideas I can get.

If the sled is set to 12v power line, then the AUX power and AUX ground lines are not shared with any connection. I built a tally system for my PRO 2 sled and PRO 2 UJB/LJB. I took an old Proformer battery, wired it up to use the PTAP on the C/M battery position. When connected to the AUX battery position, it would send the signal up the centerpost to the AUX port, came out one pin to the photosensor, the return power (if light was present) came down the AUX ground line and back into the box. From there, I had two RCA style plugs with cables: 1 that connected to the connector on the Cinetronic Gen 2 tally input, and another that simply went to a bright RED LED that I velcroed to my monitor.

 

I recently got a CineLive sled and I'm using a Media Blackout tally system, but I still have the old tally system around for my PRO 2 setup in case I have two live gigs back to back.

Willliam, thank you for that info. That is exactly what I am looking to do. It sounds like it can be done with a little work. I have thought about using the Zalex tally system and repurposing the power and ground wires for the tally sensor. That way the system already has a power source and the only thing I have to worry about is the sensor wires.
