This cable is used for connecting the RS-232 interface to a PC or other serial device.
“HDK UART” Data Packet Structure
Data packets sent as byte-aligned frames over the asynchronous RS-232 UART Serial interface. This
helps maintains compatibility with asynchronous 8N1 framing and synchronization if channel errors
exist.
The packet is the same structure as described in the AMBE-3000™ Vocoder chip Users Manual.
