Data Acquisition/Central Data Logging
E-6 Verbatim Owner's Manual
Programming an autodialer/RTU for VOICE ONLY defeats polling calls from
the SCADA Central Computer since the unit will only answer by voice and not
assert a modem answer tone. However, VOICE ONLY answer mode does not
affect data calls made FROM the RTU to the SCADA Central Computer or
CDL Printer.
If your SCADA Central Computer is not operational you may wish to program
the answer mode to VOICE ONLY. Customers who purchase the SCADA
option for their autodialer/RTUs in advance of installing their SCADA Central
Computer should use this programming command to make the unit function as a
non-SCADA networked autodialer. In addition to programming the answer
mode to VOICE ONLY make sure there is no 1st phone number programmed.
(The 1st phone number does data only calls to the SCADA Computer.)
u To program the Answer Mode, press:
986 N
Where N is 0 (default) for DATA-to-VOICE or 1 for VOICE ONLY
! Note:
Does not apply to Central Data Logger (CDL) units. CDL units never receive
polling calls and always answer in VOICE ONLY mode. The 1st phone number
must be programmed to call the CDL printer.
E.8 DATA/VOICE Autocall Calls for SCADA &
Central Data Logger
Autocall calls may function substantially the same in SCADA and Central Data
Logger (CDL) units as in standard, non-SCADA units. However, different
operating modes of Autocall may be programmed in addition to the usual
Autocall functionality.
v Exceptions:
l Autocall calls may be restricted to only calling the SCADA Central
Computer or CDL printer. Also, Autocall calls may be restricted to calling
just the personnel numbers programmed into the unit (i.e. no calls to
SCADA Computer of CDL printer). And finally, Autocalls may call both
personnel numbers and SCADA Computer or CDL printer numbers.
l Autocall calls made to the SCADA Central Computer or CDL printer
result in logging and printing of the Autocall session. No
acknowledgement is required or is possible.
l Autocalls calls made to personnel numbers will be standard voice
annunciation sessions.
