RS485 module
This module can be used to export the UART pins linked to the UART peipherals on
the dsPIC by using signals which are compatible with the RS485 standard (see Figure
3.24).

The module has three jumpers named JP1, JP2, and JP3 which can be used for the
• (first RS485 line) JP1 in position 1-2 enables the transmission (TX) from the signal
• (second RS485 line) JP3 in position 1-2 enables the reception (RX) from the signal
• (second RS485 line) JP1 in position 1-2 enables the transmission (TX) from the
• JP1 controls the termination of the RS485 line;
• JP2 in position 1-2 enables the reception (RX) from the signal TXEN of the
TXEN of microcontroller (1 = ON); in position 2-3 enables the TX; if open disables
the TX.
TXEN of the microcontroller (0 = ON); in position 2-3 enables the reception; if
open disables the RX.
signal TXEN of microcontroller (1 = ON); in position 2-3 enables the TX; if open
disables the TX.
