PCL-711

Updated: April 19, 2023

The PCL-711 card is the most versatile of the three. It has 16 digital inputs and 16 digital outputs (these are simple; you just read or write an I/O port). It has one analog output (this too is fairly simple; you just write the 12-bit value to an I/O port). It also has 8 analog inputs (these function like the ISO-813's analog input ports). There is no configuration for the digital I/O; they're fixed. The configuration of the analog input is the same as the ISO-813 card—mainly the selection of the gain.

Note: Note that for both the ISO-813 and the PCL-711 cards, there are jumpers on the card to control the input range and whether the input is single-ended or differential. We're not going to discuss these jumpers further, because they have no impact on the software design.
