Digital I/O Ports

The DMP 64 provides six digital I/O ports that can trigger external events from DMP 64 actions, or allow external events to trigger DMP 64 actions. The DSP Configurator software provides pre-configured scripts with a fixed set of common trigger and event combinations. When selected, the script is compiled and placed onto the File Management system of the device. For more advanced or custom scripts, contact an Extron Electronics Applications Engineer.

When no scripts are active, the digital I/O ports default to DI (digital input) and inactive (‘Logic Hi’ ≈ +5 VDC). The DI detects a Logic Hi as +5 VDC and Logic Low (active) as less than +1 VDC.

A DO (digital output) sends a Logic Lo as less than +1 VDC and a Logic Hi as +5 VDC. For every script that involves a DO, two versions are available to provide either a Logic Hi or a Logic Lo response to any action. The alternate script is designated as Reverse DO.

To build a script and place it into the DMP 64 File Management system:

1.From the tools menu, click Configure Digital I/O>Build Digital I/O Configuration.

2.This brings up a dialog that allows selection from a list of pre-configured scripts.

3.Select a script from the Select a Digital I/O Configuration section. The event description section describes the script and how the digital I/O ports act while the script is running. Highlight the desired script, then click OK.

4.A dialog box appears, verifying the file has been successfully uploaded to the device.

NOTE: When performing this procedure in Emulate mode, the connection dialog appears between step 3 and step 4. DSP Configurator connects and then disconnects during the procedure, returning to Emulate mode when the Digital I/O has been configured.
