Page 117 The pDDL can support a second serial port by utilizing a FT234XD USB to serial UART interfaced to the USB lines of the pDDL. The sample circuit below shows how this is done. Drawing App-D: FTDI USB to Basic UART © Microhard Systems Inc.
Page 118 Answer: In addition to the basic serial port settings, the IP Protocol Config has to be configured. Refer to the COM0/1 Configuration pages for a description of the different options. ___________________________________________________________________ Additional topics will be added in future releases. © Microhard Systems Inc.
