Examples of automated vehicles using transponder systems Figure 1 The 2-dimensional Antenna HG G-98830ZA utilizes a concept, which has a large read- ing area with a constant linear transponder positioning function. As soon as a tran- sponder is underneath the active antenna area its code as well as its deviation from the antenna center in X and Y direction is output.

In order to set the positioning threshold correctly (refer to section 5.2.2.3 on page 37), it is useful to record a complete test run over the set track. The serial interface of the antenna HG G-98830ZA may be used accordingly (refer to sec- English, Revision 01, Date: 06.12.2016...
Commissioning HG G-98830ZA tion 4.2.4 on page 28). For this function Antenna HG G-98830ZA offers the use of the serial interface (refer to section 4.2.3.1 on page 16) or the CAN bus mes- sage object 3 (see section Table 9 on page 24). Afterwards adjust the position- ing thresholds so that a safe positioning is possible but that is not triggered by side lobes.
Commissioning HG G-98830ZA This means that if there are high interference voltages in the 64 kHz area the antenna will not read a new transponder code after leaving the reception range of a transpon- der for the period of 2 ms * Level to Noise Error. In case a new transponder enters the reception range during this period the NOISE counter is reset but the old code is held.

Annex HG G-98830ZA Annex Procedure 3964R For the computer interconnection between antenna <—> SPS a 3964R-Protocol may be used. As the antenna outputs data cyclical, this results in some simplifications during implementation of the 3964R. The following diagrams describe the procedure.
Annex HG G-98830ZA Data direction PLC -> Antenna In this direction commands are transmitted only when required (by now the command for starting the monitor program is implemented; see section 4.2.3.1.2 page 19). In or- der to be visible between the frequent cyclical data output of the antenna, the 3964R of the antenna has a lower priority (see Figure 23).
Annex HG G-98830ZA Data direction PLC -> antenna Commands are transmitted into this direction if necessary. Each command must start with a „=“-character (hex 0x3d). The format of the commands is described in 4.2.3.1.2 on page 19. The telegram is to be finished with a 8 bit check sum over all characters.
