The I/O Plus option for the Lincoln adds a RS485 tranceiver. In order to run this example you will need the following equipment:

* 1. Two Lincolns with the I/O Plus Option populated
* 2. Two COM ports on a computer
* 3. Two wires to connect the RS485 port

Please follow these steps to run the RS485 master and RS485 Slave example:

* 1. Compile the uart_rs485_master example.
* 2. Program one of the Lincolns with the binary and this will be the Lincoln used to transmit CAN messages
* 3. Compile the example with the "#define CAN_TRANSMIT" set to 0
* 4. Program the other Lincoln with the binary and this will be the Lincoln used to receive CAN messages
* 5. Disconnect the power to both boards
* 6. Connect the two boards together with the 2x5 to 2x5 ribbon cable on J13
* 7. Open a terminal window for each board set to 115200, 8 data bits, no parity, 1 stop bit, and no hardware handshaking
* 8. Connect a COM port to COM1 of each Lincoln board
* 8. Apply power to the Lincoln that will receive the CAN messages
* 9. Apply power to the Lincoln that will transmit the CAN messages
