Item Name
Codes (0-3) to select the activity that will cause the
instrument to make a call into a host system.
Date of the next scheduled call-in. When used, this parameter
is normally incre- mented to the next calendar date by the
host data collection computer so that a future call-in will
occur.
Time of the next scheduled call-in. When used, this parameter
is normally set once and then reused for the next day's call-
in. However, the data collection computer might make slight
adjustments to optimize call throughput if schedul- ing a
large number of units.
Codes (0-3) to select the retry strategy that is to be
implemented by the instrument based on the following
guidelines;
Host: Host is responsible for retrying failed call-ins after the
initial hand shake. If a call-in fails, the instrument is
responsible for retrying only until it receives the "+-+clralms"
string from the host. Thereafter the instrument will not retry if
the call is dropped. (It expects the host to do so.)
Instrument: Instrument is responsible for retrying failed call-
ins. For alarm call-ins, the call is considered successful when
a sign-off command is received at the instrument. For
scheduled call-ins, the call is only considered successful if
the host writes a '0' to item 338 (Scheduled Call-in Occurred).
Until that happens, the instrument will call back after a
dropped call, or even after a sign-off command.
Status of scheduled call-in activity. "1" (Yes) indicates call-in
activity has occurred. "0" (No) indicates call-in activity has
