Reading techniques and connection possibilities
Bar code - The bar code is a machine- readable code whose information is encrypted in bars of differing widths and gaps. Bar codes come in many different forms for varying applications.
2D-code - The 2D data matrix code (ECC 200) is able to store large substantially higher quantities of data in a minuscule space by means of elements arranged in a matrix. This code type benefits from “Reed Solo- mon” error correction, which permits partially destroyed codes to be successfully read.
Direct marked 2D code - As modern cameras with intelligent lighting are capable of decoding even poor contrasting codes, it is possible to apply codes directly onto objects. Depending on the inscription method used (printing, laser or needle), a data matrix code or dot matrix code is drawn. This process is particularly suitable as a method of ensuring part traceability.
RFID technology - This method of identification is not an optical technique but an inductive one, which uses transponders as data carriers. Benefits of RFID are its suitability for use in hostile or dirty industrial environments, system functionality even without a visual connection and the in-process updating of data (e. g. for process control purposes). Depending on the range HF (13,56 MHz) or
UHF (868 MHz) can be used.
RS 232 C interface - The RS 232 C interface is also known as V 24. Data transmission between the host (PLC/PC) and reading device takes place in the asynchronous mode.
PS2 keyboard interface - Looping a handheld scanner into the keyboard interface is a simple and convenient way of transmitting data to the PC using the same format as a keyboard.
USB port - Modern PCs and handheld scanners can interchange data directly via the USB port. This variant is compara- ble to the keyboard interface. Partially with COM port emulation available.
Bluetooth interface - Bluetooth is a wireless transmis- sion technology using ISM band (2.4 GHz). Class 2 permits a transmission range of up to 10 metres. Using Bluetooth version V 1.2 resp. 2.0, disturbance of WLAN networks is practically excluded.
