Important Considerations

• When replacing an older I/O module (172109-01 Rev D, 172103-01 Rev F, 172115-01 Rev E, or future revisions), it is necessary to upgrade the monitor’s firmware to the latest released version.
• Failure to upgrade the firmware before replacing the I/O module will result in an I/O Module Mismatch and 562 ADC Failure in the System Event List.
