vrf Difficulty extracing alternate data values from text file

Question asked by VRFuser on Mar 18, 2008
Hi,


I have some USB to Serial Converters to use as an additional COM port.

Because you can communicate with the equipment via hyperterminal (USB to Serial interface ), the interface seems to be properly installed.

1) Open your VEE program and check its Interface Properties.
   Check the address of the serial interface.

2) Open Agilent IO libraries and find RS-232 serial interface
  (COM*) available on your computer.

  Its Logical unit number must coincide with VEE program's
  address of the serial interface.

  If different, change the Logical unit number after clicking
  "Change Properties". You might check communication with the equipment
  using Interactive IO.

May this information help you.


Regards,
FUKUI Yutaka
