Configure USB Device Port 
 
The setting, “USB device port” in the Utility 
menu determines whether the internal storage 
is seen as an internal or external drive. When 
set to Disk Drive, the internal storage can be 
accessed via a USB connection to a PC or via a 
USB OTG cable on a smart phone. When the 
USB device port is set to Communication, the 
unit can be used for remote control. 
When connected to a PC via the Mini-B USB port, 
the USB device port must be set to 
Communication in order to save files. See page 
124. 
From the Utility menu, press USB device port 
and select the USB interface type.

A Note about USB OTG: 
  USB OTG functionality is only supported 
on some smartphones/tablets running 
the android operating system.  
  If your smartphone/tablet supports USB 
OTG, a file manager that supports USB 
OTG as well as a USB OTG cable are also 
needed.  
  To use USB OTG, connect the GTL-253 
Type A - Mini-B USB cable to the USB 
OTG cable. Connect the OTG cable to the 
smart phone. The GDS-200/300 should 
now be visible on the smartphone’s file 
manager.
