Studio 1-3 Control Port Connection Details

Each studio can be controlled externally via the optional RB-OA3R rack control system or, if
the studio uses the Sonifex S2 mixer, the S2-MTBS panel which can be connected to the unit
via these control ports. Each control panel enables control of the Offer, Accept and Sustain
functions as well as Dump and Delay.
There is a pin for each function which needs to be pulled low to activate the function.
There is also a pin that becomes grounded once that function is selected. This is so that an
indicator such as a tally LED can be used. There is also a Digital Ground and 15V supply.
The connectors are 15 pin Female D-types.
