  • Page 5: Information About This Manual

    – the manual: „ADbasic“, which contains all instructions for the compiler ADbasic. With this easy-to-learn real-time development tool you can initialize your ADwin-Gold optimally for your control processes or for your control or measurement tasks. Please pay attention to the following information Please pay attention to the information given in this documentation and in other mentioned manuals so that the ADwin system works appropriately.

  • Page 6: Adwin System Features

    Distinctive features The ADwin-Gold system is equipped with analog and digital inputs and outputs, a fast processor (32 bit floating point signal processor) and a local RAM. The processor is responsible for the whole real-time processing in the system. The applications are running independent of the PC and its workload.

    These two outputs are optionally converted by a 12-bit or 16-bit analog-to-digital converter (ADC), (see Figure: Bock diagram ADwin-Gold ). With the 12-bit ADCs it is possible to sample very fast with the 16-bit ADCs highly accurately.

  • Page 10: Operating Environment

    The ADwin-Gold is operated with a protection low voltage of 10 to 18 Volts and is not life-threatening. For operation with an external power supply, the instructions of the manufacturer applies.

    4. Initialization of the Hardware 4. Initialization of the Hardware If you start initializing do not connect any cables to the ADwin-Gold before you have executed the following steps: – carry out the driver installation at the PC or notebook (see manual „ADwin Driver Installation“).

  • Page 12: Inputs And Outputs

    All inputs and outputs may only be operated according to the specifications given (s. annex A-1 „Technical Data“). In case of doubt, ask the manufacturer of the device, to which you want to connect the ADwin-Gold system. Please avoid connecting and operating at the analog inputs when the ADwin- Gold system is switched off.

    +9...18V Figure 5-2: Power supply connector (male) If you operate the ADwin-Gold together with a PC, the system can get its power supply by using the power-connector of the link adapter. For using the system with an external power supply unit you need the subminia- ture connector described above of the series 712, with the article number: 2 99-0406-00-03.

  • Page 14: Analog Inputs And Outputs

    The power supply from the ADlink or ADlink-PCI board also connects the earth of the ADwin-Gold with the earth of the PC. If you do not operate the PC and the ADwin-Gold system in the same place, you should not use the power supplied by the PC but an external power supply unit which if fully earth-free, in order to avoid influences by different ground reference potentials.

    At „single ended“ inputs all outer conductors of the BNC sockets are connected via jumper Jx with the common ground (GND-connection). The ADwin-Gold is delivered with the jumper setting for differential inputs, that Jumper (Jx) means the jumpers (Jx) are only plugged into one of the two pins. For the „single-ended“...

    Trigger input (EVENT) The ADwin-Gold is equipped with an external trigger input (EVENT). With this trigger input processes are triggered by an external signal (trigger) with rising edge and can completely and immediately be processed. (see ADbasic manual, chapter „Structure of an ADbasic-Program“).
