Connection Procedure
Connect a USB keyboard directly to the instrument using a USB cable. You can connect or remove
the USB cable regardless of whether the instrument’s power switch 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 keyboard. When the power switch is on, the keyboard is detected and enabled
approximately 6 seconds after it is connected.

peripherals.
• Do not connect multiple keyboards. You can connect one keyboard, one mouse, and one printer.

connect or remove one USB device before you connect or remove another USB device.

becomes available (approximately 20 seconds).
Entering File Names, Comments, and Other Items
