A customer asked me the following:
On which connections of the DMD-T665 Charging Base should I solder a USB-C charging cable with 5V+ and 5V- wires in order to power the Charging Base via USB-C?

The connections for 5V+ and GND are generally straightforward. Does the DMD-T665 charge in this way, or does the USB-C cable also need connections for DET and RS5V?

Is it already possible to connect the Remote 1 to a DMD-T665 via RX/TX connection?
Is the connection possible via the 12V voltage converter supplied with the DMD-T665?
In other words, can I wire the green (TX) of the Remote 1 to the purple (RX) of the 12V voltage converter and the yellow (RX) of the Remote 1 to the blue (TX) of the voltage converter and get a functioning RX/TX connection between the Remote 1 and the DMD-T665 via the voltage converter?
Is RX/TX from the voltage converter 12V to 5V IN routed through to the DMD-T665?
Is there already a pre-configured splitter that can be connected in the line between the voltage converter and the DMD-T665 or can the Remote 1 actually only be supplied with voltage from the motorbike and must be paired via Bluetooth?

Kind regards

Michael

Either I have not used the right search terms or there is actually no information on this topic in this forum?
I have received the T665 new and set it up. However, I am unable to enter my credit card details in Google Pay. The following error message appears:
“Mobile payment cannot be set up on this device.
Your device does not fulfil the security standards for contactless payment. It may be rooted or running uncertified software….”
Is it generally not possible to use Google Pay (NFC) on the T665 or are there alternatives to Google Pay with the same scope that can be run on it?
