Chapter 4: Operation and other communication parameters, use the eV+ FSET program instruction. The eV+ des- ignations for these ports, when referenced in the eV+ ATTACH or FSET instructions, are shown in the following table. NOTE: To configure the port speed and other communications parameters, use the eV+ FSET program instruction. Table 4-4. Serial Connectors and eV+ Designations RS-422/485 Connector The RS-422/485 connector is a 9-pin DB9 male connector. The pin assignments are shown in the following table. RS-422 is a point-to-point protocol for connecting to a single destination. This port can also be configured as a multidrop port (RS-485). Table 4-5.
RS-422/485 Connector Pin Assignments To change the configuration of the RS-422/485 port, see Configuring Serial Ports on page 31. See the previous table for the eV+ designation when referenced in the eV+ ATTACH or FSET instructions. 4.5 Connecting User-Supplied Safety and Power-Control Equipment The user-supplied safety and power-control equipment connects to the system through the XUSR and XFP connectors on the controller.
