This manual serves as an end-user manual to configure and use the DaqMux in softwarethrough the IOC. 

Overview

The DaqMux system is shown in Figure 1. The DaqMux component of the FPGA in the application board of the ATCA allows the user to choose to stream up to four streams to the software (IOC) of the input streams routed to the DaqMux. All ATCA projects are configured to have two DaqMuxes, one associated with each AMC daughter board, summing a total of 8 streams routed to software. Each of the two DaqMux has 20 streams of data routed to its input. Acquisition can be either continuous, single, or single many times. In all three cases a trigger is needed. In the continuous case (i.e. continuous mode), at every trigger, the DaqMux acquires a number of configured bytes (i.e. Frame count) and sends them up to software. In single acquisition (trigger mode), the DaqMux is armed only once, and a number of configured bytes (i.e. Frame count) is sent to software with or without a header. Single many times acquisition is just a sub-case of single acquisitions, however; auto re-arm is enabled, and everytime there is a trigger a number of configured bytes (i.e. Frame count) is sent to software with or without a header.
