Description
Description
A simple USB to serial and RS422 adapter for the DN2500F and DN2000 Denon remote controllers. Uses a FTDI 231XS for USB to UART, and a MAX485 (or one of its variants) for the RS422 signal adaptation. It has a mini DIN 8 output to connect directly to a Denon 2500F/2000 remote head unit. I'm also making a new PC library to control the unit using C and C# based on another open source library.
