ATA5570 Multifunction Read/Write Transponder with Sensor Input

The ATA5570 is derived from the T5557; however, it is enhanced by an additional sensor input. Depend-
ing on the connected sensor resistance, the uplink data is sent either in direct or inverse mode.

To promote the sensor functionality, a special application board is available, ATAB5570.

Even though the ATA5570 transponder has its own menu item (see

Figure 5-19

), the software routines

of the T5557 are used. Hence, to operate the ATA5570 refer to the instructions for the T5557/ATA5567,
see

Section 5.3.4 ”T5557/ATA5567 Multifunction Read/Write Transponder”

Figure 5-19. ATA5570 Mode Selection

Note:

To read out the traceability data, jumper J2 on the transponder board has to be replaced, and the Inverse
Data check box in the Configuration Setup menu must be selected. Do not execute the Transponder Config-
uration command.
