5   Opticon PX-20 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.

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.
