5.15.10 Interrogator
Connector Power
Through the software options, the sampler can switch the
12 VDC power at pin A of the interrogator connector. This
power-saving feature will power this port only when communica-
tions with the sampler are likely. This feature also may be used
to provide timed control of a connected device.
Power Always On
–
Select this option to always provide power
at the interrogator connector.
Power On/Off Times
–
Select this option to switch on power
only during user-specified times of the day. These times would
coincide with your data collection schedules. Up to four pairs of
Power On/Off times may be entered.
Power ON/Off times are useful when powering a user-supplied
external modem or cellular phone for data collection. If the con-
troller is equipped with the optional internal dialout modem,
pin A also will be powered if a programmed dialout condition is
true.
Because this pin can be switched under program control, it is
possible to use this output to open or close relay contacts which
operate an external pump or other device.
Alarm Dialouts Only
–
Select this option to power this port
only when a programmed dialout condition is true. This option is
intended for applications that use the optional internal dialout
modem with a cellular phone. To control the operation of other
external devices based on alarm conditions, use
