The digital lines can be configured as input or output. Each channel includes an RC filter, protection circuitry, and a programmable pull resistor. When an NI ELVIS III application board is detected, they are all automatically configured as pull-up resistors. The following table shows the channel mapping.
|Application Board Terminals||Signals|
|Bank A||A/DIO0, ..., A/DIO19||DIO 0, ..., DIO 19|
|Bank B||B/DIO0, ..., B/DIO19||DIO 0, ..., DIO 19|
You can use the NI ELVIS III Prototyping Board to access these signals. The following diagram shows the NI ELVIS III with the digital I/O terminals highlighted.
