You’ve installed all the hardware and have loaded the configuration settings into the HAL. You are almost finished. All that is left is to verify that everything is configured correctly and the audio is working properly, and then save the final system configuration to a file.
At this point, you have already viewed the RADs’ LEDs and DRs' LCD screens to verify that they are functioning properly and that the proper RAD and DR models were installed (if the HAL was pre-configured). Although the LEDs and LCD screens provide valuable information, you can glean even more information from within Halogen.
note: If you do not have a configuration file, you may want to create a simple verification configuration so you can test that the installed devices are working properly. See Task 7: Verify and Troubleshoot Installation for details.
note: It's possible that some of the ports on the HAL have been configured for devices that will be connected sporadically (for example, RAD or DR devices on a rolling A/V cart). In this case, you will see Device Missing messages on any configured port to which no device is currently connected. But in this situation, the condition is expected and no troubleshooting is needed.
tip: If you want to double-check which physical hardware device you are viewing within the software, try using the Locate feature. For details, see Locating a Device.
After verifying that the EXPs, RADs and DRs are configured correctly and working properly, you should perform an audio test. You can perform this test the old-fashioned way by wandering about and checking the actual audio, or you can perform your audio test from within the Halogen software. To do so, start the audio and then view the audio flow in the Processing Map (in the Processing Workspace). Open output block properties and view their meters in real time. Or, if needed, add a meter block where appropriate for verifying the audio. You can also, of course, view the Signal and Overload LEDs on the RADs, the HAL, and/or the EXPs to verify that the audio signal is flowing correctly.
We already delivered our lecture on the benefits of saving your configuration to a backup file – so we won’t do that again. Instead, we’ll just tell you how to do it.
Even if you do not have a pre-defined configuration file or the necessary information to create one for your system, you can still test that the installed devices can send and receive audio signals. Use Halogen to create a simple verification configuration. This procedure assumes that you have installed and connected the HAL and all the EXPs, RADs, and DRs, and have verified that the devices are communicating successfully (by viewing their LEDs or LCD screens.)
Configure the port to match the detected device. You can do so by dragging and dropping the correct EXP, RAD or DR from the hardware palette onto the port, or you can select the correct EXP, RAD or DR from the Model Picker (accessed by clicking the arrow on the right side of the port).
warning! If you have installed a pre-defined configuration file, you would rarely use this functionality. The Device Mismatch message serves as an alert that an EXP, RAD or DR was installed or configured incorrectly. Simply changing the model to match what is detected erases this alert, obscuring the fact that a mistake was made. And, most importantly, replacing a configured device with another model removes all instances of the original model from the Processing Map. The system designer would be rather unhappy, don't you think? In this case, however, when you’re simply creating a configuration to test the transmission of audio signals, adjusting the ports to match the devices that are installed makes your job much easier! We do recommend, however, that you check your EXP, RAD and DR installation against your drawings to confirm that they are in the correct locations. In addition, you can use the Locate functionality (see Locating a Device) for further verification.
