1. A tester for printed circuit boards (PCBs), comprising:
a test fixture having a plurality of electrical contacts for contacting the PCB s that are units under test (UUTs), wherein the test fixture carries:
a remote test peripheral master (RTPM) module, and
a plurality of remote test peripheral slave (RTPS) modules, wherein the RTPM module and the RTPS modules are connected through a remote test peripheral (RTP) serial bus to form a master/slave chain, and wherein the RTPM module is configured for communicating with the UUTs exclusively through the plurality of the RTPS modules of the master/slave chain, and wherein the plurality of RTPS modules are configured to communicate through the RTP serial bus with the RTPM module of their master/slave chain only.
