i-MOD UART i-MOD standard

The i-MOD UART connector is a standard connector defined by Keith&Koep to allow customers to easily add functions to a baseboard.
Keith & Koep offers different extension boards ranging from a simple breakout board to RS232/RS485/RS422 transceiver boards.
Customers may design their own peripherals which can be connected through a 10pol FFC cable.

This is the pinning of the connector on the baseboard.
Extension boards use the opposite numbering scheme.
Inputs and outputs are in respect to the baseboard. i.e. the TXD output of the baseboard is an input to the extension board.

Pin	Signal	Function
1	UART1_RI	RI input
2	UART1_DCD	DCD Input
3	UART1_DSR	DSR input
4	GND	Power
5	+3V3	Power
6	UART1_RTS	RTS output
7	UART1_CTS	CTS input
8	UART1_TXD	TXD output
9	UART1_RXD	RXD input
10	UART1_DTR	DTR output
