If communication is not successful, after about 30 seconds, a Communications Timeout Error dialog box appears. If
this happens, recheck your connections, and retry to establish CAN communications.
When CAN communications are functioning properly, the final step is to disable serial communications.
2.1.4 Disconnecting Serial 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 CAN link icons for the ION and axis.
CAN communication setup is now complete. You are ready to execute all Pro-Motion functions via CAN.
2.2 Activating Serial Communications
N-Series IONs of serial host interface type support RS232, RS422, and RS485 communications. For detailed
information on N-Series ION’s serial interfaces refer to the
ION/CME N-Series Digital Drive User Manual .
In the following sections we will detail how to connect from a PC to the N-Series ION’s serial connections using two
different connection schemes; RS232 and RS485.
2.2.1 RS232 Hardware Setup
Figure 2-2:
Hardware
Setup for
Communica-
tions via
RS232
For your PC to communicate via RS232 you will use the USB to DB9 serial converter cable (PMD P/N Cable-USB-
DB9) which is included with serial host N-Series ION DKs. As shown in
Figure 2-2 the DK interconnect board
directly accepts this cable at its J12 connector. Note that you should plug this cable into a USB port on your PC
different than the one already being used for the USB to 3-pin programming port cable that you used for setup and
first time verification.
In addition, the N-Series ION should be set to RS232 rather than RS485 communication. With a factory default
N-Series ION unit connected as shown in the figure above RS232 is automatically selected. If desired however, this
setting can be set and stored in the N-Series ION’s NVRAM. See
Section 2.2.6, “Setting Up the ION for RS485
Communications” for more information.
Although in this RS232 setup description we will only use Serial1, serial host N-Series IONs provide two RS232
interfaces, Serial1 and Serial2. PMD has available in its accessories library a cable that allows access to both of the serial
