OTG cabling
Posted: Thu Sep 08, 2016 12:57 am
I'm setting up a new Lenovo 7" tablet in my Mini/VTEC to serve as a cheap alternative to the X-dash. I'm trying to avoid wiring in a charger for the tablet so I'm considering OTG as a possible route. Main question is - does the DTA's 15 pin serial port have a pin with sufficient power to charge a tablet, even a trickle? If so I'll play round with OTG cabling to see if I can make it happen. Which could be tricky as I'll need 15 to 9 pin, then 9 pin to Micro-USB, or to USB and then to Micro-USB, all RS232. And yes, the tablet is OTG ready.
