Jumpers and Switches

3.8.1 UART 2

UART2 (connector X1) is selected as LIN master at default setting. JP37 Select, if SIN2 is connected to RS-232- or LIN-transceiver JP44 Select, if SOT2 is connected to RS-232- or LIN-transceiver

JP46 Select, if RS-232- or LIN-transceiver is connected to X1 pin2 (shared pin) JP30 Some terminal programs needs a connection between CTS and RTS JP39 Selects, if DTR or RTS will be used for system reset generation

JP47 Enables the LIN transceiver

JP51 Selects, if UART2 will be LIN master or LIN slave

					Note:
					UART2 has to be selected with
					JP57, to generates a system reset
