NO
.
MODIFIED CVM LATCH – When this feature is enabled and the CVM Latch Enable jumper is installed on the
programming card, the CVM input will not latch a CVM failure until the CVM input has been valid for more than
175 milliseconds. See Section 2.6.6 for more information. The factory default for this feature is
NO
.
EXTERNAL WATCHDOG ENABLE – When this feature is enabled the monitor will verify the status of an
optional external watchdog output from a Controller Unit or other external cabinet device. See Section 2.5.13 for
more information. The factory default for this feature is
NO
