SLAC National Accelerator Laboratory is building the LCLS II facility. It is a 1MW superconducting Free Electron Laser (FEL) facility capable of producing soft and hard x-rays. There will be about 300 different kinds of Beam Position Monitors (BPM) installed at the LCLS II facility. We have come up with the conceptual design for stripline, button, L-band cavity, and X-band cavity BPM electronics. The BPM controls system will use the MicroTCA (Micro Telecommunication Computing Architecture) for physics platform that consists of a 125MSPS ADC module and 250MSPS ADC module. This paper will discuss the conceptual design of the RTM electronics, system architecture, and preliminary calculation results.
