Connection Details

The KD-SW4x1 uses a serial connection. It can use a standard 9 wire cable or a minimalist 3 wire cable, since it really only uses send, received, and ground wires. The connection parameters are 4800, 8 data bits, 1 stop bit, no parity, and no flow control. The speed is low, but the amount of data is very trivial, so it's not a big issue.
