  • Page 5: Introduction

    Introduction HG G-98760-C Introduction The described antenna is especially suited for vehicles in outdoor areas, as the elec- tronic units are sealed within the antenna case. It is possible to adjust all important set- tings and values after manufacturingoftware as well as proceeding software updates via a serial interface.

  • Page 6: 1.3 Positioning

    Introduction HG G-98760-C Further, different characteristics of the antenna, like for example current consumption and supply voltage, can be measured and added to the output protocol. The serial output signal is a non-isolated RS 232 or RS 422. The positioning pulse is also galvanically isolated +24 V (20 mA) switched output.

  • Page 7: Mounting

    Mounting HG G-98760-C Mounting Inside the casing are four drill holes for four M5 screws. Make sure that the antenna is mounted correctly!

    Installation / Commissioning HG G-98760-C Installation / Commissioning NOTE! Check the operating voltage before connecting! Although the RS 422 interface reacts largely insensitive to interferences, the cable should not lie directly beside power supply cables. Establish all required connections. For the next commissioning steps connect a laptop with the antenna via a RS 422 to RS 232 interface (not in the scope of supply).
  • Page 9 Installation / Commissioning HG G-98760-C The following diagrams show examples for protocolled data: Low interference Diagram: commissioning protocol / low interference; sum voltage over the Figure 3 track In the diagram the sum voltage over the track is shown. Noise (inference) is located at 50 sampels, the signal at 950.
  • Page 10 Installation / Commissioning HG G-98760-C Whenever a transponder is crossed, initially the sum voltage will increase. Once the Threshold for Decoding has been reached, the bit TRANS_IN_FIELD is being set. It takes 4 x 8 ms (= 4 datapoints) for the transponder code to be decoded. The duration depends on the setting of Number of Equal Codes in menu Time &...
  • Page 11 Installation / Commissioning HG G-98760-C Interfered Decoding (function still existing) Diagram: Commissioning protocol / interfered decoding (function still exist- Figure 6 ing) The following diagram shows a case in which false POSI-Pulses may be generated through wrongly set parameters for Threshold for Decoding and/or Threshold for Positioning.
  • Page 12 Installation / Commissioning HG G-98760-C For this example, the thresholds are set to 100 samples. The bit TRANS_IN_FIELD is permanently set. Following a successful transponder decoding, initially a correct POSI-Pulse is generated. However, as the software does not realize that the tran- sponder leaves the antenna field (the noise is higher than the set 100 samples for the thresholds), each zero crossing of the difference voltage (not shown in the diagram) will generate another POSI-Pulse.
