Internal COMM SPM 1175 The alarm indicates a I2C fault
condition in which the device
cannot communicate with the
PGA’s or RTC.
• Expected: Caused by
Software Asserts used in
the RCS (clears with power
cycle).
• Hardware Problem: A
problem with the SPM
board needs to be
addressed when there is a
persistent condition that
does not clear with a
power cycle
1472 CPU monitoring the SPM issues
a communication failure due to
too many CRCs.
• Hardware Problem:
Change the SPM Board.
1474 CPU monitoring the SPM issues
a communication failure due to
time – out condition.
• Hardware Problem:
Change the SPM Board.
Preventive Maintenance Alarms
PM Due 3120 This is triggered one year after
service unless otherwise
noted.
• Execute annual PM as
indicated in the Service
Manual.
SPM Serial Number Mismatch 3480 Alarm indicates when the
serial number written to the
SPM does not match the serial
number expected by the EMV.
• Using RCS, program the
device with the correct
serial numbers. This is
typically seen after the
SPM has been replaced.
Correction of the serial
number should be prior to
calibration and testing the
device.
RTC Battery Low 3110 Indicate when the RTC battery
is low to prevent loss of date/
time, forensic memory, as well
as custom & last settings
• Hardware Problem:
• Change Battery.
• Check battery is properly
seated, and the clip secures
the battery in its location.
Power Cycle Needed 3121 Triggered when the device has
been in operation for over 30
days.
• NOTE: This is not
an
indication of a hardware
problem.
• (The start up self-check
alarm will be trigger if
device service is required.)
Observations
Observation Resolution
Device Hardware COMM Problem
Note that at subpopulation of older devices may need an updated CPU
board due to a hardware problem with the FTDI component on the board.
• Check device hardware.
• The USB connector panel, and USB cable may
need to be changed.
• For older devices, the USB revision may not be
compatible.
• On the PC check the Device Manager and verify
connection to both CPU and DSP.
• On the PC verify Load VCP box is unchecked.
• Check USB-PC Set UP
• Return the device to service to evaluate the FTDI
component.
