Each readout electronics (24 total) will contain provisions for the following 7 monitors: 1 temperature of readout boards (thermistor), 1 summed voltage on readout electronics (voltage across resistor chain), and 5 currents (to be determined).
The proper functioning of the readout electronics requires temperature stability and stable input power.
Each readout electronics (24 total) will contain provisions to allow readout of the 34 monitors via Controls (HDLC).
Each readout electronics (24 total) interfaces to 3 ladders (6 carrier interfaces). 27 monitor signals are routed from the 6 carrier interfaces to each readout electronics. Since each readout electronics also contains 7 monitors, a total of 34 monitor signals must be multiplexed and readout through the HDLC Controls interface on each readout electronics.
Multiplexing of 34 analog channels to a 12 bit Analog-to-Digital (ADC) converter on each of the 24 Power and Timing Boards of the Readout Electronics.
