Old M12 Chassis vs. the new NCS2015? No the power consumption and wiring of chassis is SIGNIFICIANTLY different. Also be aware, we got a number of NCS 2015 DC chassis where the power connectors were different form chassis to chassis. Some where + - + - + - + -, and some were + - - + + - - + If I remember correctly. So confirm the specific chassis in case your working with a MOP.
