Why does my Blackmagic Design URSA camera not see LTC from my :minitrx+ or UltraSync ONE?

The URSA has a dual function LTC IN /GENLOCK port. Rather than being a standard high impedance LTC input, it is a 75ohm input instead because of the Genlock functionality. This means that the TCS LTC output may not have enough current to produce a high enough LTC signal for the 75ohm load camera input.

There is a workaround however, simply use the SYNC output of the :minitrx+ or UltraSync ONE instead and select in the menu LTC out instead of Work Clock or Genlock. Select HIGH output level. The port is designed to drive a 75ohm load, so the LTC will be a healthy strong level.
