Struggling with initial setup (RaceDAC)

Can anyone shed light on how to set up the logging on the racedac?
How do tell it analogue channel 6 is a tps that is 0.75 volts at 0% throttle and 4.25 volts at 100%? How do I tell it it's %?
I have got the laptop and racedac paired, and the hyperterminal working, but it's just pages and pages of numbers.
We put CMD in which stopped the scrolling and tried several of the commands from the instructions, but between 4 of us, we can't work any of it out.
Any help is greatly appreciated.
John

    RaceDAC guys follow this forum, but maybe worth sending them link to this thread to get faster answer

    Thank you for the reply aol.
    I have emailed them now, and await their input.
    Any advice from anyone with experience of setting this up is appreciated.

    Throttle position sensor output is 0.75-4.2 V (from idle throttle opening to full throttle opening).
    TPS-sensor connected to analogchannel6 input.
    With default settings RaceDAC output is (output reading by default is millivolts):
    0-5 V -> 0-5000
    0.75-4.2 V -> 750-4200

    User sets analogchannel6 user offset to 750, command:
    UOW6,750
    750-4200 mV with offset 750 -> 0 - 3450

    User sets analogchannel6 user divider to 34, command:
    UDW6,34
    0-3450 mV with user divider 34 -> 0-100

    Now user has analogchannel6 input value from TPS-sensor 0.75-4.2 V and corresponding analogchannel6 final output value from RaceDAC is 0-100 "%"

    RaceDAC, thank you for getting back to me on here and by email.
    Me and the wife will be in the garage this evening trying it out :)
