7 Connection /commissioning (qualifiedpersonnel)HandscannerBCS 3600 ex series80 / 106 Subject to technical modificationsRevision A / 04/2019Explanation of the interfaces- USB HID (Human Interface Device)The digital scanner establishes a connection to the base station or PC / host via Bluetoothand functions like a keyboard.USB (Universal Serial Bus) is also a serial bus. The data transfer takes place via 2 lines (D+and D-). Two further lines serve the power supply of the connected devices.- USB SPP (Serial Port Profile)Der digitale Scanner stellt über Bluetooth eine Verbindung zur Basisstation oder Universal-Versorgungsmodul oder PC / Host her und fungiert als serielle Verbindung.- RS232 (Recommended Standard 232 – differential serial interface)The digital scanner establishes a connection to the base station or USM or PC / host viaBluetooth and functions as a serial connection.In automation technology, only three lines are usually used from the RS-232 interface.TxD (Transmit Data) for transmittingRxD (Receive Data) for receptionGND cable for the common reference potentialThere is no data transmission without connection of the GND line.The RS-232 interface is not bus-capable and can only be used for point-to-point connections.Functionally ranges up to 15m are possible.- RS422 (Recommended Standard 422 – symmetric serial interface)The digital scanner establishes a connection to the base station or universal power supplymodule or PC / host via Bluetooth and functions as a serial connection.Data transmission is via a four-wire line.All participants transmit via the data lines TxD+ and TxD- and receive via RxD+ and RxD-.The GND line is only to be used for large potential differences and should not be absolutelynecessary.The RS422 interface is less sensitive to interference than the RS232 interface. The reasonfor this is that the difference is always considered in the line levels. An electromagneticinterference would increase the potential on both lines to the same extent. Thus theinterference would have no influence on the differential signal. (For comparison: With theRS232 interface, the interference would only have an influence on the signal lines, but noton the reference potential).The RS422 interface is bus-capable.Functionally, ranges of up to 1000m are possible. It may also be possible to install repeatersin the bus for power amplification.
