"EOT" (Ctrl-D) during instrument Sign-on. If the "ENQ"
is not received in the specified time, an error "21" (Time-
out error) is transmitted from the CNI4. This item is
usually set to 7-seconds but when a Cloud Link 4G
Modem is installed, the value must be set to at least
20-seconds. Range: 7 to 60,
The time (in seconds) the CNI4 waits for the "SN"
protocol com- mand (Sign-on) following the receipt of
the "ENQ" before issuing an error "21" (Time-out error).
This item is usually set to 7-seconds but when a Cloud
Link 4G Modem is installed, the value must be set to at
least 20-seconds. Range: 7 to 60.
No specific function for this item other than to store a
numeric value, for any reason. Examples of stored
numbers: phone #, meter #, installation date, map
coordinates, elevation, etc.
Second location for a stored number. Same purpose as
item 118 above.
Codes (0-3) to indicate whether the input switch
filtering algorithm is enabled for either or both input
channels. In general, switch filtering should be "On"
when the input channel is wired to a mechanical-type
switch (such as a reed switch) or "Off" if the input
channel is wired to an electronic pulse output (such as
the corrected volume pulses from an electronic volume
corrector). Use Raw Item Access to change the selection
for the codes listed below.
Battery voltage reading, measured at last wake-up
Low voltage limit for main battery, initiates a low voltage
battery alarm (Item 099) if the value a item 048 drops below
this limit.
The voltage level at which the unit goes into Shutdown,
meaning no more pulses will be accepted until the battery is
replaced.
User selected time period that determines how often a Time-
related, 4-item audit trail record is placed in audit trail
memory. The four audit trail items are selected at items 258 -
261.
