    Default Problems communicating with laptop and Datalink 4.1.1

    Hello.

    I am having issues trying to connect the laptop to the racepak IQ3 dash.

    I have the correct cable, serial to 3.5mm and have also made a new cable with the pinouts that Ric Shaw gave me, as he was tuning the car.

    I tried on my laptop with the Datalink 4.1.1 software, and tried 2 different USB to Serial converters.
    When you try and connect via the scan ports option, it finds the port, but says 'transmit error'.

    If you set the com port manually and try and do a vnet read, it errors with a transmit error also.

    Ric tried 2 different laptops, one with USB to Serial, and one with serial only, and had same result.

    If you have any ideas that would be great.

    Dash works fine, was using car in weekend.

    Here are some screen shots of the issues also, to help you try and work out what is going on!

    IQ1 shows that the USB-Serial is set up for COM4.
    IQ2 shows the result of the COM scan. COM 4 is opened, but h as a receive error.
    IQ3 shows the preferences screen where I selected COM4.
    IQ4 shows the result of a READ VNET, with the reveive error also.
