Connecting a USB Keyboard
You can connect a USB keyboard and use it to enter file names, comments, and other items.

You can use the following keyboards that conform to USB Human Interface Devices (HID) Class
Ver. 1.1.
• When the USB keyboard language is English:
104 keyboards

USB Ports for Peripherals
Connect a USB keyboard to the USB port for peripherals on the left side panel.
Connection Procedure
Connect a USB keyboard directly to the DL850/DL850V using a USB cable. You can connect or
remove the USB cable regardless of whether the DL850/DL850V power switch is turned on (hot-
plug support). Connect the type A connector of the USB cable to the DL850/DL850V, 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.
Note
• Only connect a compatible USB keyboard, mouse, printer, or storage device to the USB port for
peripherals.
• Do not connect multiple keyboards. You can connect one keyboard, one mouse, and one printer to the
DL850/DL850V.
• Do not connect and disconnect multiple USB devices repetitively. Wait for at least 10 seconds after you
connect or remove one USB device before you connect or remove another USB device.
• Do not remove USB cables during the time from when the DL850/DL850V is turned on until key operation
becomes available (approximately 20 to 30 seconds).
Entering File Names, Comments, and Other Items
When a keyboard is displayed on the screen, you can enter file names, comments, and other items

Entering Values
You can use a USB keyboard to enter the values of items with
123
marks on the menu screens by
pressing CTRL+N on the USB keyboard to put the DL850/DL850V in the NUM LOCK state.
