Using the GPIO Port
Configuring the Control Port Outputs
To access Control port configuration, left-click on the
DCi DA Amp Rack
). Now, right click on the desired
DCi DA amp icon within the selected rack, and then select
Configure Control Ports
from the list. A new tab labeled “(amplifier name) – Control Ports” will open.
Key Control port output configuration points:
• The 2 Control port outputs support binary control only.
• There is a polarity control on each output so that it may function as active-high or active-low.
The Control port output configuration options can be found directly below those for the inputs. No parameters can be assigned to the outputs. Instead, there are three modes
available: Manual, Report Errors, and Report Online Status. Manual mode enables direct control over the selected output. In Report Errors mode, the output status will
change if any errors are reported to the network, such as clip errors, temperature errors, line voltage errors, etc. Finally, in Report Online Status mode, the output status will
change if no network communication is detected for at least 60 seconds. The Control port output does not turn off right away when reporting errors or online status. There
are several reasons for this. The online status does not change quickly; it can take up to 60 seconds to drop offline or to recover. In these modes, the output is intended to be
used with devices such as a backup amp switcher or an electro-mechanical system. Therefore, it is desirable to prevent this output from toggling on/off quickly. It may take
the output up to 90 seconds to recover (i.e., switch states) from an error or loss of connection.
Control Port Output Fields
Output
This fields identifies each output port, labeled 1 and 2.
Parameter Assignment
This field lists the parameters currently assigned to each control output.
Mode
This option determines the conditions under which the output status will change, with the following modes available:
•
Manual
– With this option selected, the output state can be manually controlled using a button in Audio Architect.
•
Report Errors
– With this option selected, the output state is active when any enabled error is reported. The indicator will stay on for up to 60 seconds after the
error is cleared. Errors include:
• Load Supervision
• AC Line Voltage is out of range
• Hardware Protection (faults)
• Over temperature (any channel or the power supply)
• Amp output clipping
• Processing output clipping (off by default)
• Analog Input clipping (off by default)
•
Report Online Status
– With this option selected, the output state is active when the HiQnet connection is lost. The length of time to wait for a time out is user
adjustable, with the default time being 60 seconds.
Output Polarity
This option enables selection between “Normal” and “Inverted” for each control output.
