AFU or copy to USB

The Pearl-2 has USB 3.0 ports that you can use to copy recordings to external USB flash drives or hard drives. Use this to conveniently provide speakers with a copy of their presentation before they leave the presentation venue.

A USB port is available on the back and front panel of the Pearl-2.

The USB storage device must be formatted with one of the following file systems:

FAT16 FAT32 XFS
EXT2 EXT3 EXT4
NTFS exFAT

We recommend you only connect one USB device to a Pearl-2 at a time. Only one copy or move to USB operation is permitted at a time, even though the UI may appear to let you start a second one. Please wait until the first is complete before starting a new operation.

AFU to a USB storage device

Transfer recordings to a USB storage device automatically when you select an external USB device as the AFU protocol transfer type using the Admin panel.

Prerequisites

Configure AFU upload to a USB storage device using the Admin panel

The fix it link disables any other type of automatic file upload you have configured. When you are done with USB uploads, return to the **Automatic File Upload **configuration page and reconfigure your AFU settings.

Do a one-time move/copy all recordings to USB storage device

When one-time move/copy of files is configured, the Pearl-2 automatically starts copying files as soon as you connect a USB storage device to the USB port.

Newest recordings are copied first. Files continue copying over until one of the following events occur:

File that are currently recording do not transfer until recording ends.

The following table describes the options available for a one-time move/copy of recordings to a USB storage device.

Table 67 One-Time Move/Copy File Transfer Options

Name Description
create subfolder with serial number (<serial>) If checked, the transfer process creates a sub-folder with the system’s serial number on the USB drive. This is useful if you are using the same drive to collect recordings from multiple systems and want to know which system they came from.
create subfolder for each channel If checked, the transfer process creates a sub-folder for each channel and multi-track recorder (within the subfolder for the serial number, if that option is also selected). Files are copied to their respective folders.
remove after copying If checked, the file(s) are removed after being copied to the USB drive. Checking this box makes the transfer a move instead of a copy.
mark file as downloaded If checked, the files that are downloaded are marked with a downloaded icon when viewing file lists. This has no effect if remove after copying is checked.
ignore already downloaded files If checked, files that were previously downloaded or marked as downloaded are not included in subsequent downloads.

If your USB drive has no activity indicator to let you know when the transfer is complete, select the one-time move/copy option to remove after copying or mark the file as downloaded so that you know when the transfer has finished.

Prerequisites

Configure a one-time copy of all recorded files to a USB storage device using the Admin panel

If a conflict is reported regarding the Automatic file upload settings, click Fix it or go to the Automatic File Upload configuration page and either disable automatic file upload or switch to a non-USB based upload type.

Safely eject the USB storage device when you are satisfied all files have been copied, or if you notice the USB storage device is out of space.

Manually copy recordings to USB storage device

You can manually copy recordings to a USB storage device that is connected to Pearl-2. This procedure is separate from automatic file upload and does not need any pre-configuration in the automatic file upload page.

The following table describes the options available when manually copying recordings to a USB storage device.

Table 68 One-Time Move/Copy File Transfer Options

Name Description
create subfolder with serial number (<serial>) If checked, the transfer process creates a sub-folder with the system’s serial number on the USB drive. This is useful if you are using the same drive to collect recordings from multiple systems and want to know which system they came from.
create subfolder for each channel If checked, the transfer process creates a sub-folder for each channel and multi-track recorder (within the subfolder for the serial number, if that option is also selected). Files are copied to their respective folders.
File already exists Choose the action to take if a file with the same name already exists in the copy location: replace (default) skip rename

Manually copy recorded files to a USB device using the Admin panel

If a conflict is reported regarding the Automatic file upload, click Fix it or go to the Automatic File Upload configuration page and disable automatic file upload or switch to a non-USB based upload type.

In this example, the first file is currently recording and cannot be downloaded.

View file transfer status and cancel file copy to a USB device

During a file transfer to an External USB drive, you can monitor the file transfer progress and cancel the file transfer using the Admin panel. You can only cancel the transfer of a file while it is in progress.

View file transfer to USB device status and cancel using the Admin panel

View available USB storage space

When you insert a USB storage device into a USB port and select an **External USB Drive **action other than ignored (i.e. manual copy, automatic copy, etc), the total and free space are calculated and displayed in the Admin panel.

When you insert your USB storage device into an available USB port, an External storage usage information tab appears at the bottom of the menus panel in the Admin panel.

Safely eject the USB storage device

When you're done saving recordings to the USB storage device, you can safely eject it using the link at the bottom of the Admin panel page.

It's now safe to disconnect the USB storage device from Pearl-2.
