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

Overview

The DaqMux sub-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 words (i.e. Frame count) is sent to software with or without a header. Single Finally, single many-times-acquisition is just a sub-case of single acquisitions, however; auto re-arm is enabled, and everytime every time there is a trigger, a number of configured bytes words (i.e. Frame count) is sent to software with or without a header.

The Graphical user interface of a DaqMux is shown in Figure 2. The main graphical user interface for configuring the DaqMux is quite simple and masks a lot of the DaqMux configurations. It only allows the user to perform the following:

• Choose the source of each of the 4 streams of each DaqMux
• Stimulate a software trigger in any of the two DaqMuxes (in case trigger mode is chosen)
• Open complete DaqMux settings
• View the AMC Up Converter and Down Converter card front panel image
