Specifications Manual
1. Abstract
This manual provides specifications for the PX-20 portable 2D barcode data collector.
2. Overview
The PX-20 is a very compact data collector with a built-in 2D barcode scanner. Due to its
compact size and its Bluetooth capabilities, the PX-20 is the ideal companion scanner for
mobile devices like the iPhone/iPad and Android telephones and tablets. The supported
Bluetooth profiles are HID (keyboard emulation) and SPP (serial port emulation) Special
support is added for iOS devices that allows for the use of the on-screen keyboard, while
the PX-20 is connected. Additional to the Bluetooth wireless capabilities, the PX-20 also has
a 1MByte storage space for off-line use. The USB interface can then be used to download
the data. This is then again either as HID (keyboard emulation) or VCP (serial port
emulation). The PX-20 is fully programmable, using Opticon’s easy to use development
tools that are available for free.

connected to the host system Master or Slave mode
Security mode As per the Bluetooth 2.1 specification. The settings for this can be
configured in the user application.
Encryption Encryption is linked to the authentication setting and cannot be
enabled or disabled separately.
Communication range 3) Approximately 10 meters
Frequency 4) 2400 MHz to 2483.5 MHz
Transmission power 2.5mW (4dBm) or less
Baud rate 115.2 kbps
Antenna 5) Built in
Notes
1. This product complies with the Bluetooth 2.1 standard. The device that
communicates with this product must support either SPP or HID as well. For
other Bluetooth devices with other profiles we cannot guarantee a connection
before the products have been tested.
2. The communication speed and range of the product may vary due to obstacles
and radio wave conditions between this product and the device to which it is
connected. Conditions on the host device may also affect the communication
speed and communication range of the scanner.
3. The prospective distance may vary based on environmental characteristics.
Also note the following frequency description.
4. The frequency band of the electromagnetic radiation (2.4 GHz) used by this
product is shared by various other devices. Therefore, baudrate and
communication distance may be negatively impacted by other devices.
Baudrate and communication distance are affected by obstacles, wave
conditions, or a device at the other end.
5. This product is equipped with an antenna. Bringing this product too close to a
metallic object may degrade performance.
