Upload Status box
Used to display the steps being undertaken during the programming and verification
process. As the upload process proceeds, the user is informed of progress.
Verification of upload is done once the file has been uploaded into DRAM. Thereafter
the data is loaded into ‘Application Flash’. The latest version is uploaded into one ½ of
the flash device. The other half maintains the old version. In this way, there is an
option to revert to the old version should there be an upload problem.

6.6.1.1 Loopback Controls
These controls allow you to set the loopbacks on the payload data.
• OU Baseband Loopback - Used to loopback the data at baseband processor
level in the Outdoor Unit so that incoming user payload data is sent back to the
user via the IU/OU interconnection data cable.
• OU RF Loopback - All RF data sent out of the Local Indoor Unit to the Outdoor
Unit is looped back at the output stage of the Outdoor Unit and returned to the
Indoor Unit.
Perform a loopback as follows:
1. Select the Loopback Type by choice of arrows on the OU being tested.
2. Select the Loopback Timeout Time (in seconds). If enabled, the Loopback state
will cancel after Time seconds and the unit will return to normal operation.
