SERVICE FUNCTIONS

System Statistics

The MDXII unit keeps track of some numbers that are important to AE Customer Support.
These numbers identify bus faults, which are momentary power faults that can be used to help
verify line-power problems. You can obtain the following system statistics from the control
panel or through the serial port.
• How many times the MDXII unit's (input power) has been turned on
• How many times an overtemperature fault occurred
• How many times output has been turned on
• The amount of time (in seconds) that input power was turned on, but the MDXII unit was
not producing output
• The amount of time (in seconds) that the MDXII unit was producing output
• The total amount of energy output delivered by the MDXII unit
• Momentary power failure events
• Bus fault failures per target life
Note: Both of the counters requested by commands 207 and 208 through the serial port
indicate events per target life. If you reset a new target or reload a target life, the
counters are reset. The purpose of these counters is to help you identify line power
problems in your system.
• The total life-time counter (if supported by your MDXII unit)

Memo Function

Via Command 127 through the serial port or the memo function from the control panel, you
can input up to a 40 character text string, which is stored in nonvolatile memory. You can use
this text string to store information that is specific to your particular unit.

Clear NOVRAM

Use this function from the control panel to clear nonvolatile memory and return stored
parameters to a default state.

Check NOVRAM

Use this diagnostic function from the control panel to check values stored in nonvolatile
memory to see whether they exceed system limits. If a value does exceed system limits, the
location of the value is returned when you use this function.
