The pages listed here describe the work in electronics undertaken to support Silicon Photomultiplier (SiPM) based  readout of the Tagger Microscope for JLab Hall-D and the GlueX experiment in particular. The working design concept for the Tagger's readout involves an array of PCB boards with SiPMs and their amplifiers, summing circuits etc. suspended in a light-tight box out of the plane of incoming electrons. Each of these "amplifier" or "analog" boards are connected across a light-sealing bus board to a "control" or "digital" board. The latter set of boards principally contain bias voltage control circuitry and an architecture that allows Ethernet-based communication with a controlling PC. An added advantage of this two-tier design is the ease with which the tagger can be wired without introducing light leaks: the SiPM signals are passed into a chamber more tolerant of ambient light. (The coaxial cables can  then take the SiPM signals off digital boards.) The adjacent digram outlines this scheme.
