I'm trying to apply a tally light system: a Panasonic video switcher that sends a signal, and I want a couple of LEDs to turn on 150ft. away whenever that signal is on. That's it.
Whether I'm building it myself or not, I need to understand what the switcher does and doesn't handle, so I don't overload any of the Panasonic's components - it's a $11,000 device. Here's the information I have about its (D-sub15) control output:
Is it designed to drive LEDs directly, or would you recommend a relay? What should also be in there to protect the unit (diodes)?
The signal has to go through 150 ft. of 26 AWG (7x34) Stranded TC wire, rated at 38.5 ohm/Mft.
I might be able to use an off-the-shelf tally system - Datavideo TB5
Given the right cable, should I be able to connect the TB5 to the Panasonic directly and suppose everything will work fine, or not necessarily?
