Compatibility Lincoln 60, Lincoln 60E
The I/O Plus option for the Lincoln adds a RS485 tranceiver. In order to run the uart_rs485_master and uart_rs485_slave examples 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 as the RS485 master.
- 3. Compile the example uart_rs485_slave example.
- 4. Program the other Lincoln with the binary and this will be the Lincoln used as the RS485 slave.
- 5. Disconnect the power to both boards
- 6. Connect the two boards together with the two wires on the J14 screw terminals. NOTE: Make sure to connect the same side of the screw terminal to the same side of the second board.
- 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 is the RS485 slave.
- 9. Apply power to the Lincoln that is the RS485 master.
The following screen shot is of the RS485 examples in action.
