Firmware Upgrade Instructions
Overview Rockwell Automation occasionally offers firmware upgrades to enhance the
performance of your relay. Since the 825-P relay stores firmware in flash memory,
changing physical components is not necessary. Upgrade the relay firmware by
downloading a file from a personal computer to the relay via the front panel serial
port as outlined in the following sections.
Required Equipment
Gather the following equipment before starting this firmware upgrade:
• Personal computer (PC)
• Terminal emulation software that supports XMODEM/CRC protocol
(e.g., Microsoft® Windows® HyperTerminal)
• Serial communication cable (null-modem cable)
• Disk containing the firmware upgrade (*.S19) file
Upgrade Instructions
The instructions below assume you have a working knowledge of your personal
computer terminal emulation software. In particular, you must be able to modify
your serial communications parameters (baud rate, data bits, parity, etc.), select
transfer protocol (XMODEM/CRC), and transfer files (e.g., send and receive
binary files).
1. If the relay is in service, open its motor control circuits.
2. Connect the PC to the front-panel serial port and enter Access Level 2.
3. Save the current relay settings.
