1. Introduction
The PCIe-AIO15 is an analog input, digital input / output PCI Express (x1) board that supports 16-
to 24-bit analog to digital converter (ADC) 4 channels and digital I / O 4 channels. All of the board's
controls are designed as Field Programmable Gate Arrays (FPGAs), so they can be freely changed or
supplemented and easily upgraded to meet your needs. The board also supports various ADC input
ranges (+ 5V, + 10V, ± 5V, ± 10V).

3.3.4 Board Address Setup
If mounting works in one system that a lot of I/O ports are required, several AIO series
boards are classified according to each board address.
Distribution of each board sets it up through 4 pin DIP switch (SW5). A system is
designed of maximum four boards at the same time so as usable.

6. Conversion Time Setup
Inside AD Converter have a digital filter. The filter characteristic by filter word (FW) is different. Have
a good noise characteristic and effective bit that had better use a lot of FW, but time to get outside data
is required very much. You can use to setup a proper conversion time as refer to table 3.
