Computerized Firing System Field Setup
Taking the above diagram as a reference, notice the general layout of the Pyrodigital firing setup. This is of course only a small example, but in general, most setups follow this type of structure. If you have an aerial setup, you will typically group your racks together such that there are 15 guns per group (each PD field module has 16 cues, and each rack typically comes with 5 guns). Once your racks are cleated into their appropriate groups, a PD field module is secured to each group by screwing it into one of the racks in that group. Each addressed device is then loaded and wired into the attached field module. You are now ready to run the XLR line from field module to field module and back to the field controller. Remembering the "female has the power", you need to make sure you run your XLR line from field module to field module in a fashion that is consistent with the female end coming from the power source, in this case the field controller. Otherwise you will have to re-wire your cabling when you realize you did it backwards.
