Replacing an existing RAD or DR with the same RAD or DR model:
1. Remove the old RAD/DR by detaching the Decora plate, unscrewing the RAD/DR from
the switchbox, and unplugging the CAT 5 cable.
2. Connect the CAT 5 cable to the replacement RAD or DR.
3. Verify that the device is functioning correctly (as explained earlier in this section).
4. Attach the RAD or DR to the switchbox.
NOTE
:
When replacing a RAD or DR with the same model, HAL automatically sends con-
figuration data to the RAD/DR. You don’t have to do a thing except verify that the
RAD/DR is working properly. This makes the process of replacing a RAD or DR as simple
as using a screwdriver! Pop the old RAD or DR out, put the new one in, check for green
lights or the proper display on the LCD screen, and you’re finished.
Replacing an existing RAD or DR with a different model:
1. Follow steps 1 through 4 above.
2. Using Halogen, view the configuration for the HAL. Because you have installed a dif-
ferent RAD or DR model than was there before, you will see a Device Mismatch error for
the port on which this RAD or DR is connected. You can either load a new con-
figuration file that contains the new RAD/DR or manually change the configuration of
the port to reflect the new model that you just installed.
3. If you have made changes to the existing configuration, save the configuration to a file
(for safekeeping).
Task 6: Installing and Connecting Analog Devices
This task needs little explanation and is here simply to suggest where in the workflow we recommend
the installation and connection of analog devices. The HAL provides you with analog inputs and out-
puts. You know what to do with them!
Task 7: Verify and Troubleshoot Installation
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 work-
ing properly, and then save the final system configuration to a file.
