3.4.2.1 Keyboard interface
Virtual keyboard using Windows or Linux drivers
This option allows the device to operate without additional drivers, with the LSR118 emulating a
keyboard. This is one-way communication; it is not possible to control the device directly in this
mode. This mode will be slower than the other options as it adds an inter-character delay when
typing the barcode data.
3.4.2.2 CDC interface
Virtual serial mode using the Windows CDC driver
This option assigns a COM port and the device communicates as a virtual serial device. Due to the
nature of CDC serial port drivers, the COM port disappears if the unit is unplugged.
3.4.2.3 HID interface
Access-IS recommend the use of the HID interface for reliability. A HID interface recovers properly
in the event of accidental disconnects or system power fluctuations; a CDC interface may not
recover in these situations.
HID interface using the Access driver (Windows only)
The Access Serial Ports Service driver is fully configurable and outputs data in virtual serial or
virtual keyboard. The output can be parsed and reformatted. The serial port is permanent and does
not disappear if you unplug or hot swap the unit. This is one-way communication and the only
command that you can send to the device is
AIS_BO
to enable or disable barcode reading. Refer
to page 27 for more information.
HID interface without the Access driver
This method is only suitable is you are familiar with HID programming.
It is possible to communicate directly with the LSR118 using the operating system
’s built-in HID
drivers. In this instance, HID reports, exactly 64 bytes in length, are sent between the host and the
LSR118.
The implementation of this driver and the method of interaction will depend on the version of the
host operating system. You should refer to the HID programming guide for the operating system you
are using.
Refer to
on page 67 for the details of the HID reports used with the
LSR118.
3.5 NFC interface options
3.5.1 Serial connection
Connect the NFC module using an RS232 interface directly into a COM port.
Note: A serial LSR118 communicates directly with the COM port and does not require any
additional drivers to be loaded.
3.5.2 USB connection
The NFC module enumerates as a standard chip card interface device (CCID) smartcard reader.
When you connect the device to the host, the NFC module uses the default Windows CCID drivers.
It is not necessary to install custom drivers when running Windows XP and above.
