Laser safety notices

ATTENTION, LASER RADIATION – LASER CLASS 2

Never look directly into the beam!

The device fulfills the IEC 60825-1:2007 and IEC 60825-1:2014 (EN 60825-1:2007 and EN 60825-1:2014) safety regulations for a prod-

uct in laser class 2 as well as the U.S. 21 CFR 1040.10 regulations with deviations corresponding to "Laser Notice No. 50" from June

24th, 2007.

Never look directly into the laser beam or in the direction of reflecting laser beams!

If you look into the beam path over a longer time period, there is a risk of injury to the retina.

Do not point the laser beam of the device at persons!

Interrupt the laser beam using a non-transparent, non-reflective object if the laser beam is accidentally directed towards a person.

When mounting and aligning the device, avoid reflections of the laser beam off reflective surfaces!

CAUTION! Use of controls or adjustments or performance of procedures other than specified herein may result in hazardous light

exposure.

Observe the applicable statutory and local laser protection regulations.

The device must not be tampered with and must not be changed in any way.

There are no user-serviceable parts inside the device.

Switching off the computer

Information on switching off and shutting down the connected computer - which must always be performed before connecting

peripheral devices, such as a scanner - can be found in the appropriate operating instructions for your computer.

Connecting the IT 1920i

The adjacent figure shows the position of the cable connection on the scanner. The

individual steps for installing the cable on the scanner are described in the following.

1.To secure the interface cable to the scanner, proceed as follows:

Loosen the Phillips screw on the cable interlock on the bottom of the hand-held

scanner and, to open, push the cable interlock in the direction of the arrow to the

end position (). Insert the RJ 41 connector into the socket on the bottom of the

hand-held scanner until the connector engages.

2.To close, push the cable interlock back and secure the cable interlock by tightening

the Phillips screw ().

3.Connect the interface cable to the appropriate connection socket on the computer.

4.You may need a power supply unit for supplying voltage; alternatively, you can use

a cable which supplies voltage from the computer system. Use the pin assignments

(see "Electrical connection" on page 1) to select the appropriate cable for your

application.

5.Connect the power supply unit to the power socket (not necessary if voltage is sup-

plied from the computer).

6.Check the operational readiness of the scanner by pointing the scanning surface

towards a flat surface and pulling the trigger. A red target pattern as well as the red

illumination should now be visible. Now scan a sample label.

The scanner emits an audible signal to confirm that the label has been read; if nec-

essary, the data are now passed on to the computer.

Parameterization

The hand-held scanner can always be configured using bar codes. To do this, the bar code must first be selected on the package

insert and then the trigger actuated in order to read the code. The configuration is then immediately accepted and executed.

Several of the most important configurations are listed in the following.

A second option is to configure the hand-held scanner with the USB and RS 232 interfaces with the aid of the EZ Config PC

program. You can download and install this program from our homepage at www.leuze.com.

The program can be used to make settings and transfer them to the hand-held scanner. The configuration can also be stored so

that it can be reused at a later time.

More information can also be found in the user's guide.

The standard applications are described and summarized below.

Notice!

Additional information on the device and short instructions can be found on the Internet at www.leuze.com.

Resetting the IT 1920i to factory settings

To reset all parameters to factory settings, scan the adjacent

bar code.

Attention!

All settings are lost!!!

Trigger

To activate the read process, a trigger signal is to be sent via the serial RS 232 interface or USB interface (COM port emulation

only). The command is to be sent at the set baud rate, parity, and data and stop bits.

The command for activation is: SYN T CR ASCII decimal values: 022; 084; 013

To cancel read readiness, send a deactivation.

The command for deactivation is: SYN U CR ASCII decimal values: 022; 085; 013

Following a successful read operation, the hand-held scanner deactivates itself.

The second option is activation via the built-in trigger button.

Configuration for the Leuze standard protocol

Scan the adjacent 2D-code. The hand-held scanner is set to the following trans-

mission parameters:

RS 232 transmission with 9,600 baud, 8 data bits, 1 stop bit, no parity,

prefix <STX>, postfixes <CR><LF>.

Connecting the IT 1920i to the serial PC interface

Voltage supply via power supply unit with RS232 cable (part no. 50114517)

Required parts:

1x IT 1920i DPM-3

1x 50114517 KB 232-1 IT190x

1x 50114525 Power supply unit

Notice!

Cable KB 232-1 IT190x (part no. 50114517) uses TTL-level

(0V…5V) for data transmission. As an alternative to this,

cable KB 232-2 IT190x (part no. 50115105) can be used.

This cable works with the regular RS232 level (-12V…+12V)

and therefore features a higher interference rejection. Both

cables are connection compatible.

Procedure:

1.Switch off the PC.

2.Connect the interface cable to a free COM port (RS 232) on the computer, to the hand-held scanner as well as to the power

supply unit (if present).

3.Switch the PC back on.

4.Scan the adjacent bar code. The hand-held scanner is

set to the following transmission parameters:

RS 232 transmission with 115,200 baud, 8 data bits, 1

stop bit, no parity, postfixes <CR><LF>.

5.If necessary, adjust the transmission parameters of the

used COM port to those of the hand-held scanner.

Attention!

We recommend connecting the hand-held scanner directly to a PC or to the MA 21 or MA 41… connection units. If

connecting to other components, please note that a voltage level range is maintained on the data lines!

Connecting the IT 1920i to the USB interface (COM port emulation)

The operation of the hand-held scanner as a serial interface on a USB port is described in this chapter. With this operating mode,

a COM interface is emulated. The read data are sent to a new COM interface. The drivers with which this COM interface is emu-

lated can be downloaded from our homepage at www.leuze.com. Thus, the data can be processed further in programs which

expect data via COM interfaces.

Required parts:

(current version available at www.leuze.com).

2.Plug the hand-held scanner into a free USB port.

3.The scanner acknowledges this connection with a

beep.

4.Scan the adjacent 2D code.

5.Open a terminal program or your program for the

serial interface, select the new COM port, and

make the following settings: baud rate 115,200, 8

data bits, 1 stop bit, no parity, postfix <CR>.

Settings for reading directly marked Codes (DPM)

Automatic cycle illumination

This is the factory default setting for the IT 1920i DPM device. This setting

cycles automatically through the direct illumination modes Top and Bot-

tom and the indirect illumination mode. It is best used when there is a mix

of codes to be scanned.

Low contrast codes

This setting is recommended when reading low contrast codes. This set-

ting cycles automatically through the illumination modes with multiple

exposure settings.

Direct illumination - Top and Bottom

This setting enables the direct illumination with the upper and lower LED

bar (Top and Bottom). It is recommend when reading printed label codes

and DPMs on highly reflective surfaces.
