Chapter 4: Operation 4.4 Configuring the SmartController Configuring Serial Ports The SmartController EX motion controller has four serial I/O ports: l RS-232/Term l RS-422/485 l RS-232-1 l RS-232-2 See Connectors and Indicators on page 25 for the connector locations. To configure a serial port, use the eV+ FSET program instruction, for example: FSET (lun.num) "/BYTE_LENGTH 8 /STOP_BITS 1 /FLOW XON_XOFF /PARITY NONE /SPEED 57600" Refer to the eV+ Language User's Guide for more information on FSET. This applies to all of the SmartController EX motion controller's serial ports. RS-232 Connectors All three types of RS-232 connectors are 9-pin DB9 male (standard PC) connectors.
The user- supplied cable to connect to the RS-232 connectors should be a DB9, F/F, null-modem data- transfer cable. The pin assignments are the same for all three connectors and are shown in the following table. Table 4-3. RS-232 Connector Pin Assignments These ports support the RTS and CTS signals used for hardware handshaking (also known as modem control). By default, these signals are not enabled. To configure hardware handshaking SmartController EX User’s Guide, 11069-000 Rev.
