Overview
The basic functions of Pixelator are implemented on the NI PCI6602 Counter/Timer card. (In future, other options will be implemented that avoid NI cards altogether.)
The NI PCI6602 card provides the clock that governs the measurement dwell time and triggers detectors, often referred to as the "pixel clock". These are constructed from the first 3 subdevices (of 8 total) using the following external connections (pins grouped into the same function are connected).
| Function | NI PCI6602 Pin | Name |
| Clock Switch? | 3 | C0 Gate |
| 32 | C2 Out |
| Line Time | 5 | C0 Out |
| 8 | C1 Gate |
| Pixel Clock | 9 | C1 Out |
