Chapter 1 — About the SG20B Cordless Scanner
Connect the SG20B
The SG20B cordless scanner can be connected to a host either via a
SG20 Base Station or via the host Bluetooth interface (for example an
external Bluetooth USB adapter or an internal Bluetooth controller).
Connect as a System
In the first case, the "SG20B Scanner + SG20 Base Station" unit
works as a single system (it is called "system" throughout this
document). The base station acts as an interface between the scanner
and the host. A system can work only if the scanner is connected to
the base station via Bluetooth and if the base station is properly
powered and connected to the host using the appropriate interface
cables (USB, RS-232 or Keyboard wedge Y-cable). The system can then
be seen as a tethered scanner, except than you can walk freely holding
your scanner in your hand.
For more information on how to connect and configure a SG20B
scanner as a system, see
System” on page 27 and “Configure the Scanner and Base Station
as a System” on page 39.
“Connect the Scanner and Base Station as a
Direct Connection
A scanner is said to be connected to a host in direct connection when
it is connected to the host via a Bluetooth interface such as an
external Bluetooth USB adapter or an internal Bluetooth controller.
For more information on how to connect and configure a SG20B
scanner in direct connection, see
in Direct Connection to a Host” on page 51.
“Connecting the SG20B Scanner
Advantages of a Connection as a System
The advantages of using your scanner as a system as opposed to a
direct connection are the following:
• No need to know the Bluetooth address of the device to which to
connect the scanner and to create a Bluetooth association bar
code,
• No need to fit the host PC with a Bluetooth interface,
6 SG20B Cordless Scanner + Bluetooth Base Station User’s Guide
Page 19
• Several interfaces available: RS-232, USB VCP, USB HID, Keyboard
Wedge,
• More reliable and faster data transfer.
Scan Bar Codes
For the SG20BHP and SG20BHPHC do not look directly into the
window area or at a reflection of the laser framing beam while
scanning. Long-term exposure to the laser framing beam can
damage your vision.
The SG20B contains either a 1D linear imager (SG20B1D), a 2D
imager (SG20B2D or SG20B2DHC) or high performance 2D imager
(SG20BHP or SG20BHC) to scan bar code data. The type of scan
engine you are using and the type of bar code you are decoding
determines the way you scan the bar code.
When you unpack the SG20B, these bar code symbologies are
enabled:
• Code 39
Chapter 1 — About the SG20B Cordless Scanner
• Code 128 / GS1-128
• EAN/UPC
• PDF417 (all models except SG20B1D)
• DataMatrix (all models except SG20B1D)
If you are using bar code labels that are encoded in a different
symbology, you need to enable the symbology on your SG20B. Use
EasySet version 5.6.5.4 or later to enable and disable symbologies for
your scanner.
Note: Be sure your SG20B scanner has established a Bluetooth
connection with the SG20 Base Station (see “Connect the SG20B
Scanner to a SG20 Bluetooth Base Station” on page 34) or with
another Bluetooth device (see “Connecting the SG20B Scanner in
Direct Connection to a Host” on page 51). If your scanner is not
connected it will emit an error beep when scanning bar codes.

2 Connect your scanner to a SG20 Base Station or to another
Bluetooth device.
3 Point the scanner window at the bar code label and hold the
SG20B steady a few inches from the label.
4 Pull the trigger and use the laser framing to position the imager
over the bar code or area to capture.
Example: SG20THP Laser Framing
By default, when the SG20B successfully scans a bar code, the
SG20B beeps one time, the status light turns green for 2 seconds,
and the scanner lighting turns off.
Note: When bar code labels are printed close to each other, try to
frame only the bar code you want to read, to avoid reading the wrong
bar code.
5 Release the trigger.
Hands-Free Scanning
The SG20B is a handheld scanner however you can scan items
without having to hold your scanner in your hand. To do hands-free
scanning, you will need to change the triggering mode to Autostand.

Autostand Triggering Mode
Autostand mode is different depending on the scanner model. This
section explains the difference between:
• Autostand for or all models except SG20B1D and
• Autostand for SG20B1D
Autostand For All Models Except SG20B1D
Autostand is a mix of Level and Presentation triggering modes. When
the scanner is not in the Charge Base or Base station it is in Level
mode (pull the trigger to scan a bar code). When you place the scanner
in a Charge Base or Base Station it automatically switches to
Presentation mode. In this mode the scanner turns on automatically
when it detects movement in front of the scanner window. This allows
you to use your scanner for hands-free scanning. To return to Level
mode (handheld scanning) take the scanner out the of the base.
Autostand For SG20B1D
When using the 1D model Autostand is a mix of Level and Flashing
triggering modes (1D model does not support Presentation mode).
When the scanner is not in the Charge Base or Base station it is in
Level mode (pull the trigger to scan a bar code). When you place the
scanner in a Charge Base or Base Station it automatically switches to
Flashing mode. In this mode the scanner is flashing. This allows you
to use your scanner for hands-free scanning. To return to Level mode
(handheld scanning) take the scanner out the of the base.
Note: Autostand mode is not available when using the Desktop
Adjustable stand or the Flexible stand because it does not provide
automatic detection of the scanner. If you are using this stand with
the SG20B you must also enable the Ignore Stand Detect setting using
EasySet version 5.6.5.4 or later. In this case the scanner switches to
Presentation/Flashing mode after a configurable timeout and is not
dependent on the stand.

Chapter 3 — Connect the Scanner and Base Station as a System
The SG20 Bluetooth Base Station is successfully connected and
power is on when it emits 2 blue flashes.
5 If necessary, configure the serial parameters of your base station
using EasySet to match the host device (for more information on
serial parameters setup, see “RS-232 Interface Settings” on
page 43).
Keyboard Wedge Interface
For a keyboard wedge interface the keyboard wedge Y-cable is
connected to the 10-pin modular connector. If your host does not
provide enough power you can connect an external power supply to
the Y-cable. This will power your base station but will not provide
enough power to charge a scanner in the base. To charge a scanner
(fast charge) you must connect an external power supply to the DC
connector.
To connect with a keyboard wedge Y-cable
1 Turn off your host device.
Do not connect a keyboard wedge Y-cable to a host that is
turned on. You may damage your product.
2 Connect the Y-cable to the 10-pin modular connector of your base
station and to the host device (one end to the host and the other to
a PS2 keyboard).

Connect and Configure the SG20B
Scanner in Direct Connection
This chapter explains how to connect the SG20B scanner to a
host and how to set up the scanner in direct connection
configuration. This chapter covers these topics:
• Connect the SG20B in Direct Connection
• Configure the SG20B in Direct Connection
49
Page 62
Chapter 5 — Connect and Configure the SG20B Scanner in Direct Connection
Connect the SG20B in Direct Connection
The cordless SG20B scanner can communicate with a host device
through the Bluetooth communications Human Interface Device
Profile (HID) and Serial Port Profile (SPP). This is called a direct
connection as opposed to a connection as a system (which uses an
SG20 Bluetooth Base Station to interface with the host).
HID Bluetooth Device Connection
With the HID profile, your SG20B is recognized as a keyboard.
Connection information is stored, meaning that if the scanner loses
connection (out of range, low battery, etc.), it will try to reconnect as
soon as possible (back into range, charged battery, etc.). Moreover, no
specific software is needed in HID profile as opposed to SPP profile to
collect data.
Before trying to pair and connect your scanner, make sure:
• it is not already trying to establish a Bluetooth connection. If so,
the blue Intermec Ready-to-Work indicator blinks; read the
Bluetooth device disconnect bar code.
Bluetooth Device Disconnect
• it is not already paired with your Bluetooth device. If so, remove it
from your host’s Bluetooth devices list.
• your host is set to allow Bluetooth device connections.
Pair and Connect as an HID Bluetooth Device
This section describes how to pair and connect your scanner from
your host PC.
To pair and connect as an HID Bluetooth device
1 Turn on your scanner by pulling the trigger.

You pull the trigger, but
nothing happens.
You pull the trigger, the
red scanning beam (1D)
or laser framing (2D)
turns on, but you
cannot successfully scan
a bar code.
You scan a bar code and
the status light turns
on, but the SG20B does
not beep.
The SG20B is powered by a rechargeable lithiumion battery
discharged.
To recharge your SG20B scanner, dock it in a
properly powered SG20B Charge Bluetooth Base
or SG20 Bluetooth Base Station (see “SG20

Connections” on page 23).
Try these possible solutions:
. Make sure the battery is not fully
• Make sure that the SG20B is configured for the
symbology you are scanning.
• Make sure that the SG20B is at the appropriate
scanning distance from the bar code. Move the
SG20B closer and farther away to find the
appropriate distance.
• Make sure that the SG20B is configured for the
type (1D, 2D) of bar code you are scanning.
• Make sure the bar code you are trying to scan is
not poorly printed or too small. Scan a known
good bar code to make sure that the SG20B is
working properly.
For more information, see “Scan Bar Codes” on
page 7.
The beep duration, volume, frequency, and
number may be configured so the SG20B does not

You scan a
(configuration) bar code
and the SG20B beeps six
very fast beeps.
You scan a bar code, the
SG20B beeps once, and
the status light blinks
green once, but the data
is not transmitted to the
host computer.
You cannot establish a
direct Bluetooth
connection with your
scanner.
You cannot charge your
scanner or establish a
Bluetooth connection
with the SG20
Bluetooth Base Station.
Your scanner is
unresponsive.

Try these possible solutions:
• Make sure that your data collection application
is set up to receive data from the SG20B.
• If you are using an SG20 Bluetooth Base
Station connected to your host using an RS-232
cable, make sure that the serial parameters on
the SG20B match the serial parameters of the
host computer. The default serial parameters
for the SG20B are: 57600 baud, 8 data bits, no
parity, and 1 stop bit.
There might be a problem with your host
Bluetooth interface. Try disabling then enabling
your host Bluetooth radio from the Device
Manager.
There might be a problem with your Bluetooth
Base station connection. This is indicated by a
blinking of the SG20 Bluetooth Base Station blue
