Digital I/O Ports

The dual 4-pin Digital I/O ports monitor or drive TTL level digital signals. The ports consist of two banks of three I/Os with the fourth pin used as a ground, providing six ports total. The DSP Configurator software provides selection from a list of scripts, that can be loaded to the DMP 64. The scripts provide pre‑configured sets of functions.

From the main structure menu, click Tools>Configure Digital IO to access the scripts (see Digital I/O Ports on page 75).
