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 4820
Shown in the figure to the right are the locations for installing the cable on
the base station. The individual installation steps are described in the fol-
lowing.
1.To secure the interface cable to the scanner, 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 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 "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 "Configuration".
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
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 RS 232 interfaces with the aid of the VisualMenu 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 4820.
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 4820 to factory settings
To reset all parameters to factory settings, scan the adjacent
barcode.
Attention!
All settings are lost!!!
Return the IT 4820 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 IT 4820 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 4820 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>.

(RS 232) on the computer (3) and to the base station
(2).
3.Plug one end of the power supply unit cable into the
base station (4) and the other end into a free power
socket (5).
4.Switch the PC back on.
5.Scan the adjacent barcode.

RS 232 transmission with 115,200 baud, 8 data bits, 1 stop bit, no parity, terminators <CR><LF>.
6.Return the IT 4820 to the base station to apply the settings. This procedure is concluded with optical confirmation signals (green
LED on the ST 2020).
7.If necessary, adjust the transmission parameters of the used COM port to those of the IT 4820.
Attention!
We recommend connecting the IT 4820 directly to a PC or to the MA 21 or MA 41… connector units. If connecting to
other components, please note that a voltage level range of -14 … +14V is maintained on the data lines!
