  The silicon pixel sensor is the core component of the vertex detector for the
Circular Electron Positron Collider~(CEPC). The JadePix3 is a full-function
large-size CMOS chip designed for the CEPC vertex detector. To test all the
functions and the performance of this chip, we designed a test system based on
the IPbus framework. The test system controls the parameters and monitors the
status of the pixel chip. By integrating the jumbo frame feature into the IPbus
suite, the block read/write speed is further extended in order to meet the
specifications of the JadePix3. The robustness, scalability, and portability of
this system have been verified by pulse test, cosmic test and laser test in the
laboratory. This paper summarizes the DAQ and control system of the JadePix3
and presents the first results of the tests.
