Using the USB Duplicator
Synchronous and Asynchronous
The 1:27 USB Copy Tower SA supports two copying methods:
• Synchronous Copying
• Asynchronous
Synchronous Copying
Synchronous Copying means that all flash drives begin copying together.
Synchronous Copying is used when the source data is larger than the system buffer
(120MB).
You can check the size of the data source drive by inserting the source drive into the
USB Duplicator and using the arrow keys to first select “Information”, then select
“USB Info”.
Plug in one source and up to 27 target USB flash drives. The display will read out the
number of USB flash drives that are ready for copying and the content size. When you
have finished loading the target drives use the arrow keys to select “Copy” and then
select OK.
Asynchronous Copying
Asynchronous Copying is used when the data files are the same as or less than the
systems buffer memory (120MB). If the source data content is less than the systems
buffer memory you can copy flash drives continuously by taking out the drive which has
finished copying, and replacing it with another blank. Asynchronous Copying will start
immediately after loading the first target drive.
When this process is used the source data is read into systems buffer first. You can
check the size of the data source USB flash drive by inserting it into the USB Duplicator
and using the arrow keys to first select “Information”, then select “USB Info”.
