  • Page 7: Introduction

    Using the GEN series Master/Slave option, multiple mainframes can be interconnected to provide a synchronized multi-mainframe test system with hundreds of channels. The Master/ Slave option for the GEN series Data Acquisition System enables up to nine mainframes to be fully synchronized.

  • Page 8: How To Use This Manual

    1.1.1 How to use this manual This manual has been written to help you to benefit as fast as possible from the Master/Slave option and to get maximum results from its usage. Many people read their user manual only as a last resort. If you are one of those, the next paragraphs tell you where to find information when you need it.

  • Page 9: Requirements

    In this manual it is also assumed that you have a working knowledge of data acquisition and the Perception software. For details regarding the connection of your GEN series Data Acquisition System with your PC, please refer to the GEN series Data Acquisition System user manual.

    Installation Installing and removing the Master/Slave board The Master/Slave board is easily inserted into the GEN series mainframe and is automatically recognized by the Perception software. The board is removed and installed in the same way as all the acquisition boards.
  • Page 19 Installing the Master/Slave board To install the Master/Slave board proceed as follows: Shut down the GEN series and remove the power input cable. Ensure that the ejector levers are in the outermost position, tilting away from the board. Slide the board into its guide rails until the ejectors contact the perforated metal strips at top and bottom.
  • Page 20 Press both ejectors inwards to seat the board. They act as levers to gently push the board into its backplane sockets. Figure 2-7: Press ejectors inwards Fasten the small set screw on both ejectors on the board. Figure 2-8: Ejector set screw The Master/Slave board is installed.
  • Page 21 Removing the Master/Slave board To remove the Master/Slave board: Shut down the GEN series and remove the power input cable. Loosen the small set screw on both ejectors on the board. Figure 2-9: Ejector set screw Press the inner grey button on each ejector to release the catch.

  • Page 31: Verification

    Verification Initial check-out For an initial check-out of your Master/Slave configuration, verify as follows: Is the mainframe installed properly: fuses, power selection, power cord connected? Is the Master/Slave board installed properly? Is the fiber-optic cable between the Master/Slave boards in the mainframes connected properly? Has the Master/Slave operating mode of the mainframe been set in the Perception software?

  • Page 32: Verification Procedure

    3.2.1 Hardware set-up Set-up two GEN series mainframes with each a Master/Slave board installed and with each at least one recorder board installed. Connect a TTL level, 1 Hertz signal to the top input of the first recorder board of the master mainframe and to the top input of the first recorder board of the slave mainframe.
  • Page 33 In the Settings sheet, go to the Trigger group in the task pane and select Channel. 10 In the Trigger mode column, set all triggers to Off. Figure 3-3: Trigger mode list 11 Select the input with the connected TTL level, 1 Hertz signal on the master mainframe and set the trigger of this channel to Basic.
