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 base station
Shown in the adjacent figure are the locations for installing the cables on
the base station. The individual installation steps are described in the fol-
lowing.
1.To secure the interface cable to the base station, proceed as follows:
plug the RJ 41 connector into the socket on the bottom of the base sta-
tion until the cable clicks into place.
2.Connect the interface cable to the appropriate connection socket on
the computer.
3.You may need a power supply unit for supplying voltage if you would
like to charge the hand-held scanner via the base station or use an
RS 232 interface. Use the pin assignments (see "Electrical connection"
on page 1) to select the appropriate cable for your application.
4.Connect the power supply unit to the power socket.
5.Use the code for the respective application to configure the hand-held
scanner, see chapter "Parameterization".
6.Check the operational readiness of the scanner by pointing the scan-
ning surface towards a flat surface and pulling the trigger. A red laser
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 necessary, the data are now passed on to the computer.
Notice!
To charge the hand-held scanner, the power supply unit must be plugged in
and the hand-held scanner placed in the base station.
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 1911i / IT 1981i to factory settings
To reset all parameters to factory settings, scan the adjacent
bar code.
Attention!
All settings are lost!!!
Return the hand-held scanner to the base station to apply the settings. This procedure is concluded with audible confirmation
signals.
You may then continue making settings or operation of the device.
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 transmission parameters:
RS 232 transmission with 9,600 baud, 8 data bits, 1 stop bit, no parity, prefix <STX>,
postfixes <CR><LF>.
Return the hand-held scanner to the base station to apply the settings. This procedure
is concluded with audible confirmation signals.
Notice!
To charge the hand-held scanner, the power supply unit must be plugged in
and the hand-held scanner placed in the base station.

Connecting the IT 1911i / IT 1981i to the serial PC interface
With TTL-RS232 cable (part no. 50114517)
Required parts:
1x IT 1911i ER-3 or IT 1981i FR-3
1x 50122431 Base for IT 19x1i
1x 50114517 KB 232-1 IT 190x
1x 50123862 Power supply unit for Base for
IT 19x1i
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 con-
nection compatible.
Procedure:
1.Switch off the PC.
2.Connect the interface cable to a free COM port
(RS 232) on the computer and to the base station.
3.Plug one end of the power supply unit cable into the
base station and the other end into a free power
socket.
4.Switch the PC back on.
5.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>.
6.Return the hand-held scanner to the base station to apply the settings. This procedure is concluded with optical confirmation
signals (green LED on the base station).
7.If necessary, adjust the transmission parameters of the used COM port to those of the hand-held scanner.
Attention!
We recommend connecting the base station directly to a PC or to the MA 21 or MA 41… connection units. If connect-
ing to other components, please note that a voltage level range of 0 … +5V (TTL level) is maintained on the data lines!
Notice!
To charge the hand-held scanner, the power supply unit must be plugged in
and the hand-held scanner placed in the base station.
