Connect the TLC-8 Controller to CCUs that require a contact closure input for tally.
The RU-2 connects just like one of our tally lights but rather than LEDs has two contact closure outputs (on a 3.5mm jack).
The RU-2 includes a twelve inch RJ-45 cable to connect to the controller and a two and a half foot pigtail with a right angle 3.5mm connector at one end and bare tinned leads at the other. Simply add a connector that matches your CCU's tally port.
