19.2  Using the DLM4000 as a USB Storage Device
This section explains the setting that enables you to use the DLM4000 as a USB storage device 
through a USB connection made between the USB port on the DLM4000 rear panel and a PC.
► “USB Communication (USB Function)” in the Features Guide
UTILITY System Configuration Menu
Press UTILITY and then press the System Configuration soft key to display the following menu.
 
Set USB Function to Mass Storage.
Note
•   From a PC, you can access the DLM4000 internal memory as a storage device. You cannot access the 
DLM4000 network drives or the storage media connected to the DLM4000 USB ports.
•   When USB communication is set to Mass Storage, a connected PC can use the DLM4000 as a read-only 
storage device.
•  If you operate the files from the DLM4000, the DLM4000 will temporarily disconnect the connection from 
the PC so that the screen displayed on the PC can be refreshed.
When using a DLM4000 with firmware version earlier than 2.00 as a USB storage device
On models with firmware version earlier than 2.00, the mass storage feature for Windows XP and Windows 
Vista PCs is different from that for Windows 7. On models with firmware version earlier than 2.00, if the 
DLM4000 is accessed from a Windows XP or Windows Vista PC, the files on the DLM4000 internal memory 
can be read, deleted, and saved.
