STATE 
This field enables or disables the -411 test mode.  If an EOS option is present, it will be engaged 
when the STATE is toggled on.  This field may also be used to reset a fault condition occurring 
on the EOS option due to a temperature or over current fault. 
EOS STATE 
This field can have one of three values: 
N/A  Indicates no EOS option is present or the EOS option was not powered up when 
the STATE was enabled. 
ACTIVE  The EOS option is active. When active, the –411 firmware will use the EOS for 
voltage dips at 0, 40 or 70% test levels. If a second generation EOS is used and 
the 70/80 Tap selection on the EOS is set to 80%, you must still program 70 as 
the DIP TO level to activate the 80% tap as the firmware only has one control 
code for this tap.  Thus, the 70% programmed level will activate the 70/80 tap. 
The actual level will be determined by the setting of the EOS in this case. 
OFF  The EOS option is in Bypass mode.
