USB2ANY: Discrepancies between user guide and device

Part Number: USB2ANY
Other Parts Discussed in Thread: BQ25120A, EV2400

Hello there,

I am writing to bring to your notice some inconsistencies with the USB2ANY device and the documentation and software. It was sent to me along with the the BQ25120A EVM instead of the EV2400. I was trying to make connections using jumpers and I ran into these issues.

1. The diagram for the connection shown in the image is the opposite of what I am able to do on my physical device (see image):

2. As a result of (1), the connections shown in the user guide is different from what shows up as assignments in the USB2ANY software (see image):

As a result, I am not able to connect the BQ25120A EVM to the PC, I keep getting the "Device ACK Error" on the Battery Management Studio.

Thanks,

Ashwati

    Hi Ashwati,

    The connection of USB2 IDC cable should be connected to the middle of J4 connector, see the image below. The IDC connector's key (10pin) on the enclosure defined the orientation of the connector. Also, red line indicates pin1 of the ribbon cable and triangle on the IDC connector indicates the position of pin1. So the USB2ANY pin connection is correct. 

    In addition, USB2ANY GUI only works with Windows 32bit OS. You have to use Window 7, 8 in 32-bit or Windows 10 32-bit (rarely used by customer). 

    Our team (Precision Op Amp Application)  does not support BQ25120A product. I am going to forward you to power team.The 10-pin IDC cable connector seems to be correct from the I2C software image above, see green rectangular. Cable Pin1 and Pin2 are SDA and SDL I2C connection on the USB2ANY device. I do not know where pin9 and pin10 are from. Maybe it is connected to other side BQ25120A's I2C interface. 

    Best,

    Raymond

    Hello Raymond,

    Thank you for the clarification - based on the red wire, yes, pin 1 makes sense, it looks like the wire was mounted the other way around in my piece. I am aware that J4 needs to be used, my image circle got shifted by mistake. 

    I am using a 64-bit system, so does that mean that the USB2ANY cannot be used with the EVM to communicate with I2C. 

    The USB2ANY was shipped along with the EVM, and the board isn't even designed for that connector, so thank you for forwarding my query to them, because I am not able to communicate with it right now. Let me know how I can follow up.

    Thanks,

    Ashwati

    Hi Ashwati,

    The USB2ANY is not the right interface board and you will need EV2400 along with Battery Management Studio to get up and running. 

    I will reach out to you privately to see what we can work out for your design.
