Just bought a CIH 1200, it has the Early Riser II monitor. It has 2 smaller screens. Will it show planted population? I have the Early Riser with big screen for my CIH 900 planter. Will that work on the 1200 planter as is with the same harness?

Or will the later model Early Riser IV that came with some CIH 1200 planter work on the same Harness as the Black Box Monitors?

Thank You!
