Data Acquisition/Central Data Logging
Verbatim Owner's Manual E-3
The purpose of the quick intercall delay is for more expedient in transitioning
from data calls to voice calls. However, in certain cases the quick intercall
delay may actually interfere with attempts to call the autodialer/RTU for
acknowledgement. This is especially true for cellular interfaced units.
Cellular phone calls often take substantially more time to connect to the called
party. Therefore, on cellular interfaced units you may need to lengthen the
quick intercall delay to allow a longer time "window" for acknowledgement
calls from the SCADA Central Computer.
u To set the quick intercall time, press:
919 V
Where V is 35 to 999 secs.
Default is 60 secs.
! Note:
Available ONLY on units with firmware revision between V1.36 to V1.99.
Applies only when the autodialer/RTU is advancing to the first voice number.
Does NOT apply to data call retries, calls between successive voice numbers
or wrap-around from last voice number to data calls again.
E.3 Acknowledgment Calls To The SCADA
Central Station
Units configured for SCADA operation may be programmed to make calls to
the SCADA Central Computer to report alarms which were acknowledged by
personnel. Alarm Acknowledgement which occurs during calls to personnel or
when personnel call the unit will prompt a sequence of Acknowledgement calls
made to the SCADA Central Computer. The purpose of Acknowledement calls
is simply to log the event of alarms being acknowledged by personnel.
u To program the unit for Acknowledgement Calls, press:
982 V
Where V is one of the following:
l 0= OFF - (Default)
l 1= ON - Make Acknowledgment calls
l 2= resets all alarm acknowledgement call status - inhibits all
further attempts for this alarm acknowledgement occurence.
