Description
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 not occurred from the
point in time this item was last reset. Following the
successful transfer of data, this item is intended to
be reset to "0" by the data collection computer just
prior to instrument sign-off. Also see item 336.
User supplied phone number the instrument will
call when the Scheduled Call-in feature is enabled
via items 333 and 486. The time of the scheduled
call is deter- mined by items 334 and 335.

User selectable parameter to set the amount of

time (in minutes) to wait until repeating the Call-
out Window set by the Call-out Keep Alive Time
