Theoretical and practical realization of the JTAG testing system for the RPC Muon Trigger of the CMS experiment at the LHC accelerator at CERN laboratory (Geneva) is presented. The paper covers issues related to tests of connections of the printed circuit boards (PCB) of the RPC Trigger. Functionality test of devices and modules were performed. Special test were designed for large PLD FPGA. Testing environment for the JTAG model is discussed. The model is based on some existing and some newly developed testing algorithms. Practical system realization is presented. The system consists of the hardware interface and the software layer. Software was built using C++ object oriented language and databases. Exemplary test of the RPC Muon Trigger electronics was performed and the results were given.
