Lincoln UART RS485 Example
From Manuals
Compatibility Lincoln 60, Lincoln 60E
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
