cate with the relay via the RS485 ports, the Slave Address, Baud Rate, and Parity will have to be manually pro-
grammed. When communications is established, the saved setpoints will have to be reloaded back into the 489. See
the next section for details.
c) LOADING SETPOINTS FROM A FILE
An error message will occur when attempting to download a setpoint file with a revision number that does
not match the relay firmware. If the firmware has been upgraded since saving the setpoint file, see Section
e): Upgrading Setpoint Files to a New Revision on page 3–10 for instructions on changing the revision
number of a setpoint file.
The following procedure demonstrates how to load setpoints from a file:
1. Select the File > Open menu item.
2. 489PC will launch the Open window and list all filenames in the 489 default directory with the 489 extension. Select the
setpoint file to download and click OK to continue.
3. Select the File > Send Info to Relay menu item. 489PC will prompt to confirm or cancel the setpoint file load. Click
Yes to update the 489 setpoints.
