How to Connect a USB Storage Device
When connecting a USB storage device to the instrument’s USB port, connect the USB cable 
directly as shown in the figure below. You can connect/disconnect a USB cable at any time 
regardless of whether the instrument is on or off (hot-plugging is supported). Connect the type A 
connector of the USB cable to the instrument, and connect the type B connector to the USB storage 
device. If you connect a USB storage device when the power switch is on, the device becomes 
available for use after the instrument identifies it.
The instrument has two USB ports: USB-0 and USB-1. The port numbers are not fixed. The port 
where the first detected USB storage device is connected to becomes USB-0. The second detected 
USB storage device becomes USB-1.
