  During the ATLAS phase II upgrade, the tracking system of the ATLAS
experiment will be replaced by an all-silicon detector called the inner tracker
(ITK) with a pixel detector as the most inner part. The monitoring data of the
new system will be aggregated from an on-detector ASIC called Monitoring Of
Pixel System (MOPS) and sent to the Detector Control System(DCS) using a new
interface called MOPS-HUB. The hardware components of the MOPS-HUB, firmware
specifications for the FPGA of MOPS-HUB and its integration plan will be
presented. In addition, an irradiation plan for the new system will be
introduced.
