Rs-232 / Lin; Table 2-4 Fp4 (Uart) Jumpers; Table 2-5 Uartdn Signal Jumpers - NEC AB-050-FX3-U User Manual

To program the device via the UART interface the following jumpers must be closed:
For Flash programming using the PG-FP4 device power can either be supplied by the PG-FP4 or by the AB-050-
FX3.
a) For PG-FP4 power supply open JP2.
b) For AB-050-FJ3 power supply close JP2.
If the clock supply for PG-FP4 programming is not on board, close CN48 Pins 25-26 to supply the clock from PG-
FP4.

2.5 RS-232 / LIN

Close CN49 1 – 2 and 3 – 4 to supply power to RS-232 / LIN bus drivers.
For the LIN bus drivers additionally a VBAT voltage must be supplied. This voltage must be in a range of 5V to 12V.
For the exact specification refer to the Datasheet of the LIN Drivers.
To supply VBAT to the board use either of the two connections:
- Use TP1
- Close JP19 and use Cn16
Close the following jumpers on CN9 to physically connect the UARTD signals from the Electrical Area to the
Functional Area.
