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!

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.
