The supplied SCL cable is both a communication and data cable in one jacket. It is used for both the static white BLANCA series and the RGB PARATA DMX series.
For operating the Blanca BSP715, only the 5-wires, black, white, green, grey, & violet, are used. The other two wires, orange and bare drain wire can be capped individually and not used. These additional wires are used when used with other modes of communication.
