Using The Usb Interface - Denso AT10Q-SM User Manual

3.2 Using the USB Interface

The scanner receives and sends data from/to the host computer through the USB-COM interface or USB keyboard
interface. You need to set up the device driver designed for the interface to be used.
Notes for connecting the USB interface cable
To use the USB-COM interface, you need to install the serial port driver to the host computer before connection of
the USB interface cable. For details, refer to Section 3.2.1.
When connecting the USB interface cable to the host computer, fit the ferrite clamp (that comes with the scanner)
on the cable in the direction of the arrows at a location shown below until it snaps into place.
When plugging and unplugging the USB connector, put an interval of at least 10 seconds between those actions
since Windows may take several to 10 seconds to add or delete the USB device.
Hot plugging/unplugging is allowed for USB devices. However, do not plug or unplug the USB connector when:
- The computer is on standby (in suspend mode) or
- The COM port is open with the USB-COM interface being used. (Hot plugging/unplugging under this condition
will lose data.)
When the host computer is processing the scanner connection, do not plug or unplug any other USB device cables.
Directly connect the scanner to the USB port on the host computer or to the self-powered hub. The scanner may not
be connected to some types of hubs. If the operation of the hub-connected scanner is unstable, connect it directly to
any USB port on the host computer.
Do not use any extension cord.
