Black goes to Input 1, green/blue goes to Ground, and red/brown goes to any of the +5 terminals (only needed for an accessory like a probe). These can be hooked to the terminal blocks by loosening the screw with a small flat head screwdriver, inserting the stripped wire end, and tightening the screw back down. Make sure there is a good connection to the wire (don?t insert the wire far enough for the screw to clamp down on the plastic insulation).
