1 Click the Connect toolbar button.
2 Select RS232 and then click OK.
3 Enter the same serial port settings as were programmed into the ION previously.
4 When complete, click OK.
If RS232 communication is successful, an additional set of graphical icons representing your N-Series ION and axis
will be loaded into the Project window. If communication is not successful, after about 2 seconds, a Communications
Timeout Error dialog box appears. If this happens, recheck your connections, and retry to establish RS232
communications.
When RS232 communications are functioning properly, the final step is to disable serial communications to the ION’s
Serial3 programming port connection
2.2.4 Disconnecting Serial3 Programming Port
Communications
The last step is to disconnect the programming port serial connection. To accomplish this:
1 Select the serial link version of the ION in the Project window.
2 Click the Disconnect toolbar button. A dialog box appears asking if you are sure you want to disconnect.
3 Click OK. You will notice that the serial ION icon and axes graphical icons in the Project box disappear,
leaving only the Serial1 RS232 link icons for the ION and axis.
RS232 communication setup is now complete. You are ready to execute all Pro-Motion functions via RS232.

RS485
In addition to RS232 communications at Serial1 and Serial2, N-Series IONs support RS422 and RS485
communications via the Serial1 interface. Communicating by RS485 is typically less of a 'plug and play' process than
communicating by RS232 however, and requires the user to create their own cables.
RS422 is essentially a subset of RS485 which uses a similar differential electrical interface but has only a single node
connection. We will therefore focus on RS485 and show how to wire a network of RS485-connected N-Series IONs.
