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 1900
Shown in the adjacent figure is the location of the cable connection and trigger
button of the scanner. The individual steps for installing the cable on the scanner
are described below.
1.To secure the interface cable to the scanner, proceed as follows:
Insert the RJ 41 connector into the socket on the bottom of the hand-held
scanner until the connector engages.
Connect the interface cable to the appropriate connection socket on the com-
puter.
2.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.
3.Connect the power supply unit to the power socket (not necessary if voltage
is supplied from the computer).
4.Check the operational readiness of the scanner by pointing the scanning sur-
face towards a flat surface and pulling the trigger. A red target line 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
necessary, the data are now passed on to the computer.
Configuration
The hand-held scanner can always be configured using bar codes. To do this, the barcode 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 RS232 interfaces with the aid of the EZ Config PC
program. You can download and install this program from our homepage at www.leuze.de.
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.
Further information on this can be found in the User's Guide for the IT 1900/1902.
The standard applications are described and summarised below.
Notice!
Additional information on the device and short instructions can be found on the Internet at www.leuze.de.

Resetting the IT 1900 to factory settings
To reset all parameters to factory settings, scan the adjacent
barcode.
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 IT 1900 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 IT 1900 is set to the following transmission parameters:
RS 232 transmission with 9,600 baud, 8 data bits, 1 stop bit, no parity,
prefix <STX>, terminators <CR><LF>.

1x 50114525 Power supply unit
Notice!
The KB 232-1 IT190x cable (part. no. 50114517) uses TTL level (0V…5V) for data transmission. Alternatively, the
KB 232-2 IT190x cable (part. no. 50115105) can be used which 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 IT 1900 as well as to the power supply unit (if
present).
3.Switch the PC back on.
4.Scan the adjacent barcode.
The IT 1900 is set to the following transmission parame-
ters:
RS 232 transmission with 115,200 baud, 8 data bits, 1
stop bit, no parity, terminators <CR><LF>.
5.If necessary, adjust the transmission parameters of the
used COM port to those of the IT 1900.
Attention!
We recommend connecting the IT 1900 directly to a PC or to the MA 21 or MA 41… connector units. If connecting to
other components, please note that the voltage level range is maintained on the data lines!
