I found pinboard wires the best to connect the serial-USB adapter. They slot right into the PCB holes but wasn't able to get past the boot up screen. Despite this I had no joy so returned it to FOSCAM who replaced under warranty. The replacement bricked as well - same version firmware, same...
I have two new R4 and managed to brick one (BSOD during firmware update).
The dud I have a serial USB connector connected and all I see in PuTTY is the boot screen, I can't interrupt it or get any commands to the device.
