2 Installation
2.1.1 Switching off the PC
NOTICE
Make sure that the PC is switched off before connecting the scanner.
2.2 Connecting the base station
Shown in the figure below are the locations for installing the cable on the base station.
Connection for interface cable
2.2.1 Connecting to base station IT 1911i
1. To secure the connection cable to the base station, proceed as follows: Insert the RJ 41 connector into
the socket on the bottom of the base station until the cable clicks into place.
2. Connect the other end of the connection cable to the appropriate connection socket on the PC.
3. You may need a power supply unit for voltage supply if you would like to charge the hand-held scanner at
the base station or if you use an RS 232 interface. Use the pin assignments (see page 8) to select the
appropriate cable for your application.
4. Connect the power supply unit to the power socket.
5. Configure the hand-held scanner using the codes for the corresponding application; see chapter
"5 Configuration" or the external document "User’s Guide IT 1910i/1911i".
Leuze electronic IT1911i 6
6. Check the operational readiness of the scanner by pointing the scanning surface towards a flat surface
and pulling the trigger. A green 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 PC.
2.3 How do I scan codes?
This section explains the best way to scan codes:
The scanner must be held at a slight angle to the
bar code. (Do not hold the scanner at a right angle
to the bar code.)
The green LED line which serves as an alignment
aid should be positioned at the center of the code.
This ensures that the center point of the camera is
aligned with the code.
(The scanner will not be able to detect the label
correctly if it is not fully captured by the camera.)
The green LED line is smaller and narrower if the
scanner is held closer to the code. Small codes
should be read at a smaller reading distance. With
larger codes, the reading distance must be large
enough so that the camera can capture the
complete code.
2.3.1 Testing the scanner
The adjacent bar code can be used for testing the scanner, the module
size is 0.5 mm (20 mil)

5.7 Activating the read process
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.
To cancel read readiness, send a deactivation.
Following a successful read operation, the IT 1911i deactivates itself.
The second option is to use the trigger button to establish read readiness.

5.9 Troubleshooting
For problem detection and troubleshooting, examine your scanner as follows:
1. If the scanner is supplied with power via the connection cable, the scanner and PC must be connected to
each other before the scanner is commissioned. The PC must supply the scanner with 5 V DC. Check the
manual for your PC to ensure that the power supply is adequate for connecting your scanner.
2. Make certain that the connection cable is securely connected to the PC. You can find information on
properly connecting the scanner in the manual for your PC. Support is also available from your technical
staff.
3. If your system operates with an external voltage supply, make certain that the power supply unit is
properly connected to the scanner.
4. Check that the connection cable is securely connected to the base station. At the base station, please
loosen the cable using a small pin: the connector is unlocked.
5. If, even after performing all of these measures, the scanner is not ready for operation, replace the power
supply unit with a different recommended power supply unit which you are certain functions properly.
6. Make certain that your scanner's interface is compatible with the PC. Further information on this topic can
be found in the manual for your PC. Also check whether the scanner has been configured for the desired
application. This information is given in the User’s Guide IT 1910i/1911i.
7. Check whether the bar code labels which you would like to scan are of suitable quality and that the used
bar code type is recognized by your scanner. Damaged bar code labels (crinkled, torn or soiled) may be
recognized poorly or not at all by the scanner. If you suspect that the problem lies with the quality of the
label, check the read readiness with a label of relatively good quality.
8. If the problems are still not corrected, please contact the Leuze electronic hotline (see chapter 8).
