The Main I/O connector is a DB15 female, and carries data, power, and Tally Inputs.
Pinouts are as follows:

Camera Control Interface
Camera Control is connected via various pins the MAIN I/O connector to your CopperHead
Base Station or directly to a camera. The OCU has four electrical control interfaces (RS422,
RS232, "Sony bi-di," and "Panasonic bi- di") which are automatically determined when each
emulation is selected. However, they can be changed via the "ENGr" menu if necessary for
type and sense (see
Power
The CHRCP2050A runs on DC power, which is supplied from the CopperHead Base Station
or directly from the camera, and is supplied via the MAIN I/O connector. If the
camera/camcorder does not have enough power to supply the OCU and/or TFT-LCD, an
optional connector and AC adaptor are available for powering the units externally.
Tally Inputs
Tally inputs are found on the MAIN I/O connector (DB15). Both Red and Green tally inputs
are available. These can be configured for either voltage or contact closure. Voltage must
be positive reference ground. Contact closure is also reference ground. An open collector
bipolar NPN transistor or open drain N channel FET may also drive the inputs. Configuration
is via the ENGr menu.
The panel tally LED is a bi-color Red/Green with the priority Red.
