# DanceDongle - A USB to FTDI to RS-485 + Next for the Disco Dance Floor
A simple little PCB with two main components, an FTDI USB to ttl-232 converter
(FT232RL) and a ttl-232 to RS-485 converter (ISL81487 8-SOIC), and the RJ-45
connector wired for the DiscoDanceFloor project.
## Connected channels
##### FTDI PWREN - 485 Read Enable
Enabled the 485 receiver when the FTDI is on
##### FTDI TXDEN - 485 Drive Enable
Enable the 485 transmitter whenever bytes are sent
##### FTDI RTS(out) - RJ-45 Next (P3)
Use RTS to assert (hold low) the Next line
##### FTDI CTS(in) - RJ-45 Next (P3)
Use CTS to detect asserted line
##### FTDI DSR/DCD - RJ-45 Detect (P4)
If a slave is connected to the RJ-45, it will pull these lines low.
