Using a USB Mouse
You can connect a USB mouse and use it to perform the same operations that you can perform with
the DL850E/DL850EV keys. Also, by clicking a menu item, you can perform the same operation that
you can perform by pressing the menu item’s soft key or selecting the menu item and pressing the
SET key.
USB Ports for Peripherals
Connect a USB mouse to a USB port for peripherals on the left side panel of the DL850E/DL850EV.
Usable USB Mouse Devices
You can use mouse devices (with wheels) that are compliant with USB HID Class Version 1.1.
Note
• For USB mouse devices that have been tested for compatibility, contact your nearest YOKOGAWA dealer.
• Some settings cannot be configured by a mouse without a wheel.
Connection Procedure
To connect a USB mouse to the DL850E/DL850EV, use one of the USB ports for peripherals. You
can connect or disconnect the USB mouse at any time regardless of whether the DL850E/DL850EV
is on or off (hot-plugging is supported). When the power switch is on, the mouse is detected
approximately 6 seconds after it is connected, and the mouse pointer (
) appears.
Note
• Only connect a compatible USB keyboard, mouse, printer, or storage device to the USB port for
peripherals.
• Even though there are two USB ports for peripherals, do not connect two mouse devices to the DL850E/
DL850EV.
