Having problems with WPQ864 board

  1. 7 months ago

    Hi. I just received my WPQ864 from compex, and was looking forward to doing some tests with it.
    However, my board fails to turn on with 12VDC of power being applied to its DC input jack
    The full model number is WPQ864 6A01PR32F512R-TE
    While looking at the hardware guide, the guide mentioned LV and HV versions of this board. which would be the case for me?
    Also, is the DC power jack on this board center tap positive?
    I tried to reach for help via e-mail, but there was no answer :(
    Also, I am guessing that this answer would not be able to be answered in public, but anyone able to send me the root access password for when I succeed in turning this board on?

    Thanks!

    Hi Djji,

    For the early models of the WPQ864 embedded board, it may not have been written whether it is the low voltage (LV) or high voltage (HV) version. Current production units are all HV version.

    The following is a guide to differentiate between the two versions.

    Here is the front view of the WPQ864 LV board:

    This is the back view of the WPQ864 LV board:

    Next, three photos of the WPQ864 HV board are given with the differences in red boxes.

    The PR3, PR4, and PR5 connections are present on the front of the HV board:

    The PR69 and PR70 connections are absent on the front of the HV board:

    The PR67 and PR1147 connections are present on the back of the HV board:

    Yes.

    There is no password required. You can directly enter the shell by pressing 'Enter'.

    Best,
