This detector, composed by 3 layers of cylindrical triple GEM detectors, is the appointed upgrade for the BESIII inner tracker. BESIII is an electron-positron spectrometer based at Institute of High Energy Physics in Beijing, China. The electronic chain is composed by an ASIC, designed in Turin for the analog reading of the channels (called TIGER), an FPGA based read out card (called GEMROC) and a data collector module (called GEM-DC). During the last year I continued the work on the GEMROC firmware optimization, debugging it and reaching the design goal for the device. I was also very involved in the assembling and data acquisition of a planar GEM cosmic ray test setup in Ferrara. In such frame I finalized the acquisition software that I have already developed and carried on part of the analysis of the data acquired.
