LabView

  • Test_Byte_Bit_50.vi: This example outputs a digital byte on bank 1 of a L4450 card and reads the result as input on bank 2. A single bit of the output is then changed and the result is read and examined to verify the correct response. The examples assumes there is a cable connecting the two banks.
  • TestSeq_50.vi: This example shows how to create, use, and delete sequences. It happens to use an L4450 card, but sequence operations can be used on any L4400 series card.
  • Test_StaticIO_50.vi: This example shows how to do static digital output and input on the L4450 card. The example assumes a cable is connected between bank 1 and bank 2 of the card. The digital operations shown would also work on an L4452 card, once the channel numbers were modified to correspond to those of an L4452.
  • Transfer_50.vi: This example shows how to create a pattern in memory on bank 1 of an L4450. It then configures bank 2 to receive a pattern and transmits the pattern from bank 1 and receives it on bank 2. The example assumes a cable is connected between bank 1 and bank 2 of the L4450 module.
  • TestOper_45.vi: This example sets up default configurations on a L4445A and then closes some of the switches.
