3.3 Mounting

Mount the LSR118 into a kiosk, gate or similar device, if required. Refer to Figure 4 for the

LSR118’s dimensions (in millimetres) and mounting points.

For optimum performance, do not position the LSR118 in direct sunlight.

NFC INSTALLATION WARNING

To optimise the performance, DO NOT install the LSR118 so that its NFC antenna is within 40 mm

of a large metal or electrically conductive component or structure.

Failure to observe this instruction may lead to the product’s NFC performance deteriorating or even

failing completely.

Figure 4. LSR118 dimensions and mounting points

Use three M3 screws (not provided) to mount the unit. Maximum insertion depth is 6 mm; minimum

recommended insertion depth is 2 mm.

3.4 Barcode interface options

3.4.1 Serial connection

Connect a serial LSR118 device using an RS232 interface directly into a COM port. You must

specify the baud rate, parity, data bits and stop bits.

Note: A serial LSR118 communicates directly with the COM port and does not require any

additional drivers to be loaded.

3.4.2 USB connection

Connect a USB LSR118 device using one of three possible options. These options are compatible

with all Linux and Windows operating systems from XP onwards.

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 HID reports –barcode only 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.

3.6 Barcode module installation (serial device)

A serial LSR118 communicates directly with the COM port and does not require any additional

drivers to be loaded. Serial connectors are labelled: CONN1 = Barcode , CONN2 = NFC module.

1. Switch off the computer.

2. Connect the serial cables to COM ports on the computer and finger-tighten the two thumbscrews

to secure the connectors to the port.

3. If using a USB power injector cable, plug the injector cable into the coaxial power connector on

the splitter cable and then plug the USB connector into a powered USB port on the computer.

If using an Access-supplied power supply, plug the power cable into the coaxial power

connector on the splitter cable and then connect the external power supply to an AC outlet.

4. Once the device is connected, switch on the computer.

3.7 Barcode module installation (USB device)

Note: If you intend to use the Access driver, ensure that you install the driver before you connect

the LSR118 to the computer.

3.7.1 Driverless keyboard output

There is no additional driver required for this mode. Connect the USB cable from the LSR118 to a

USB port on the computer.

3.7.2 CDC Windows driver

This method of USB installation uses the Windows CDC drivers.

For this method to operate, you must install the CDC drivers using the file, AccessISUSBCDC.inf,

which you can download from http://www.access-is.com/gettingstarted/.

The download (USB Driver for CDC Mode) includes full instructions for use.

Windows assigns a virtual COM port to the LSR118 device. You can find out the COM port number

in Device Manager. You will require the port number to configure the LSR118.

3.7.3 Custom HID

3.7.3.1 HID interface using the Access serial driver (Windows only)

The recommended method for using a USB LSR118 is to configure the device to operate in HID

mode. This allows the device to communicate with the Access driver.

For this method to operate, you must install first the Access driver (Access Serial Ports Service

(ASPS)). Download ASPS from http://www.access-is.com/gettingstarted/.

The download (ASPS Software) includes full instructions for use.

Ensure that you install the driver before connecting the LSR118 to the host.

3.7.3.2 HID interface without the Access driver

There is no additional driver required for this mode. Connect the USB cable from the LSR118 to a

USB port on the computer.

3.8 NFC module installation (serial device)

A serial LSR118 communicates directly with the COM port and does not require any additional

drivers to be loaded. Serial connectors are labelled: CONN1 = Barcode , CONN2 = NFC module.

Refer to Barcode module installation (serial device) on page 12 for installation instructions.

3.9

NFC module

installation

(USB device)

When you connect

a USB-connected

LSR118 device to the host, Windows

automatically detects the

hardware and installs the standard CCID smartcard reader drivers.

Some versions of Windows may

prompt you to search automatically for a driver.

The

NFC module

also exposes a HID interface for

configuration and control.

Refer to

NFC

management interface commands

on page

for the

command set and its responses.

In Device Manager, the smartcard reader and HID-compliant device represent the

NFC module. The

barcode

device appears under Ports (COM & LPT).

Figure 5. NFC module and barcode device in Device Manager (other device types not shown)

3.10 Test the device

Once you have connected the device and installed the relevant drivers, if applicable, you can test

the device. To do this, wave a piece of paper in front of the glass; the reader’s LEDs should

illuminate. If the device fails to respond when connected to the host, refer to the Troubleshooting

section in this document.

3.11 Barcode configuration software

Connect to, and configure, the LSR118 using your own configuration tool, a terminal emulation

program or the Access-IS configuration tool, which you can download from http://www.access-

is.com/gettingstarted/.

Refer to the Barcode command reference on page 21 for details of the barcode commands, which

you can use to configure the LSR118.

3.12 Communicate with the NFC module

Once the NFC module is enumerated, it registers itself with the Windows Smartcard Resource

Manager. Since the NFC module is Personal Computer/Smart Card (PC/SC) compatible, you can

use standard Windows smartcard functions to communicate with the module through the Windows

Smartcard Resource Manager API. Refer to the Microsoft website for more detailed information on

the Smartcard Resource Manager API.

For more information on the operation of the LSR118’s NFC reader, see page 31. Refer to page 39

for MIFARE media commands and responses and page 56 for NFC management interface

commands.

Problem

Solution

LSR118 not transmitting data to host

Check that all cable connections between the LSR118 and

host are secure.

Ensure that the unit has power.

LSR118 cannot scan barcode

Ensure that the unit is configured to read the barcode that

you are scanning.

If scanning a document, ensure that the print quality is good.

If scanning a barcode on a mobile phone, ensure that you

set the screen backlight on the phone to its brightest setting.

3.14 Maintenance

3.14.1 Cleaning

Clean the glass with a lint-free cloth. If the glass is dirty, wipe the glass with a lint-free cloth

moistened with isopropyl alcohol or use an alcohol wipe. Do not use abrasive cleaners.

3.14.2 Storage

Store the unit in its original box, at a temperature of -30°C to 70°C.

4. Barcode operating modes

The LSR118 operates in one of three ways, as defined by the AISOMD command. Refer to the

Barcode command reference on page 21 for a list of commands that you can send to configure the

LSR118.

4.1 Mode summary

4.1.1 Dumb mode

The LSR118 is a one-way communication device.

The device detects the media and activates the imager and illumination. When the LSR118 reads

the barcode, it sends the data to the host, activates the ‘Good Read’indicators, and disables the

imager and illumination. The imager and illumination do not reset until the LSR118 sensor fails to

detect any media for 0.5 seconds.

4.1.2 Host mode

The LSR118 is a two-way communication device that reads barcodes and waits for a host to accept

or reject the barcodes.

The device detects the media and activates the imager and illumination. When the device reads the

barcode, it sends the data to the host and disables the imager and illumination. The LSR118 waits

for a response from the host to accept or reject the data, which activates the ‘Good Read/Bad Read’

indicators on the device. The LSR118 waits for up to two seconds for an ‘Accept/Reject/Ignore’

command to activate indicators. The host sends an ‘Ignore’ command to reset the imager if no

response from the indicators is required. The imager and illumination do not reset until the LSR118

sensor fails to detect any media for 0.5 seconds.

The ‘Ignore’ command requires version 1.0.21 (or later) of the firmware.

4.1.3 Interactive mode

Note: This is not the recommended mode for new installations.

The LSR118 is a two-way communication device, controlled fully by a host.

The LSR118 detects the media and sends a command to the host with this information. If the media

is removed, a second command is sent telling the host that the media is no longer detected.

If the media is present, the host sends a command to activate the imager and illumination. When the

LSR118 reads the barcode, it sends data to the host. The imager and illumination are not disabled.

The LSR118 waits for a response from the host to accept or reject the data, which activates the

‘Good Read/Bad Read’indicators and disables the imager and illumination. An ‘Ignore’ command

may also be used, although untriggering the unit is more useful in most cases.

At any time, the host can send ‘Good Read’ or Bad Read’ commands activate or deactivate the

imager and illumination.
