Host Software POR-Delay: In the default setting, the modulation starts after 192 clock cycles (1.5 ms at 125 kHz) are recognized. When actively selecting POR-Delay, the modulation delay measures 8382 clock cycles (67 ms at 125 kHz) Fast Write: When Fast Write is selected, the write times in the Write menu are reduced by half OTP: If OTP is set, all memory blocks are write-protected These configuration parameters are sent to the transponder when the Configure Transponder button is clicked.
Host Software 5.3.4.4.2 Traceability Data The Traceability Data button allows direct access to page 1, which contains the 64-bit traceability data as defined by ISO/IEC 15963-1. Refer to section Section 5.4.3 ”Readout Manufacturer (Traceability) Data” for further details. Exit Use the Cancel button to terminate T5557 operation. 5.3.4.5 Data Write Figure 5-17. T5557 Write Tab The Write tab has two sections; Write Setup and Write Timing .
Host Software 5.3.5 ATA5570 Multifunction Read/Write Transponder with Sensor Input The ATA5570 is derived from the T5557; however, it is enhanced by an additional sensor input. Depending on the connected sensor resistance, the uplink data is sent either in direct or inverse mode. Table 5-2. Data Mode Depending on Resistance Resistance Pin 4-5 Jumper J2 Sent Data > 140 kΩ Open Direct < 70 kΩ Closed Inverse To promote the sensor functionality, a special application board is available, ATAB5570.
Host Software 5.3.6 ATA5577 Enhanced Read/Write Transponder with AFE-Options When the ATA5577 transponder is selected, it can be operated in either Basic Mode (compatible with the T5557/ATA5567/TK5551) or in Extended Mode for enhanced functionality. Figure 5-20. ATA5577 Mode Selection 5.3.6.1 Basic Extended Mode Selection The ATA5577 user guide describes the software functionality using the Extended Mode. Functions that are not supported by Basic Mode are indicated.
Host Software The structure of the ATA5577 user interface differs from the other transponder types. In the Setup window, four tabs – Transp. Settings, Write, Read and ISO 11784 – and the Downlink section allow the configuration, reading, writing and programming and reading transponder according ISO 11784/85 standard. 5.3.6.2 Downlink Settings The Downlink section, above the tabs, indicates the current downlink mode from the reader to the transponder.
Host Software Not released in Basic Mode: Terminator: – Basic Mode Sequence Terminator – Extended Mode Sequence Start Marker Terminator Initial.
Host Software 5.3.6.4 Selecting Write tab Figure 5-22. ATA5577 Write Tab In the Extended Mode, the Fast Write check box in the Downlink section is released (This is the only difference to the Write tap in Basic Mode). However the Fast Write feature makes less sense for programming via resonating antenna coupling, due to the needed time duration determined by the gap time of the ON/OFF Keying (OOK). Nevertheless, the feature is performed by the software.
Host Software 5.3.6.5 Selecting Read tab Figure 5-23. ATA5577 Read Tab The Read menu displays the content of the data blocks 1-7. To read data from an unknown transponder, the configuration of the transponder must be first known and entered in the Bitrate, Coding, MaxBlock and Synchronization fields. The default Read Timing is derived from the Bitrate setting and normally suitable for most transponder applications. The synchronization of the transponder can be configured in the Synchronization area.
Host Software Figure 5-24. Direct ccess Dialog Box In the Read tab, an AOR button is displayed if AOR has been configured in the Transp. Settings tab (see Figure 5-21). The execution of the command initiates the Answer on Request procedure (Section 5.4.2 ”Answer On Request AOR Mode” ). Click the Reset Transponder button to initialize a reset. This initializes the standard Read Mode of the transponder. Transponder manufacturer data can be read by clicking the Traceability Data button (Section 5.
Host Software The ISO 11784 Setting tab allows the programming and reading of a transponder according to the ISO standard 11784/85 used for animal ID or waste logistics. Opening the ISO 11784 Settings tab, the reader automatically changes the field frequency from 125 kHz to 134.2 kHz as specified by standard. The ISO 11784 Settings tab has two sections: Program Transponder and Read Transponder.
Host Software 5.4 Operating Common Transponder Features 5.4.1 Password PWD Mode The transponder can be protected from unauthorized overwriting of memory data using passwords. If the transponder is configured in password mode, each block write command sent to the transponder has to be expanded by the expected password as specifed by the content of block7.
Host Software 5.4.2 Answer On Request AOR Mode The AOR feature is used to address an individual transponder, among others in a common field. For AOR mode to function, transponders must be also be configured for password mode. Each transponder has to be programmed with a unique password. If the reader sends an AOR wake-up sequence that matches a password of one transponder present in the field, the transponder starts to transmit its ID code continuously.
Host Software 5.4.3 Readout Manufacturer (Traceability) Data The Traceability Data button allows direct access to block 1 an 2 of page 1 which contain the 64-bit traceability data programmed and locked by Atmel during production.
