Hi Team,

Datasheet shown that  pin19/20 as TX and pin22/23 as RX, if customer want to use the function, does the PIN12/11 and PIN8/9 need swap it?

    Hi Yadong,

    The connections are as follows:

    if RX2 is connected to the USB conn, then the TX2 signal will connect to RX of host.

    If TX1 is connected to the USB conn, then the RX1 will be connected to the TX of host.

    Host ->   1002A ->    conn

    TX ->     RX->TX       -> TX

    RX ->     TX->RX       -> RX
