Barnett Engineering Pro Talk ARU CV2 - Manual (Page 17)

Configuration using the PC 3-3
B1272M001 BARNETT ENGINEERING LTD. ProTalk Cv2
3.4.6 Directories
When an alarm is detected, the Cv2 will perform a specific sequence of events
determined by the entries in the directory. Six directories are available, providing
different actions for different groups.
3.4.7 Programming
The programming section is used to transfer the configuration database between the PC
and the Cv2. Recorded voices can also be transferred from the Cv2 and then back.
3.5 Configuring the Cv2
When configuring the Cv2, the sequence described in the following section is the simplest
way to get the unit operational. If the Cv2 uses any of the special port functions -- Alarm
Active, New Alarm, Acknowledge Received, Local Acknowledge or the Totalizer Reset
Input -- you must consider the relationship between these functions and the Hardware, Groups
and Points sections when configuring the unit.
3.5.1 Hardware section
Start with the Hardware section to establish settings for the input and output ports. Input ports
can be configured as Digital, Analog, Watchdog, Totalizer or Interval types. Each port can be
independently set to one of these types; an individual port can have only one type assigned.
Output ports can be either On/Off or Timed types.
To select an input for configuration click on the Hardware Inputs button to bring up the
summary of the input settings. Each of the eight inputs will be shown along with its current
type and hardware settings. The input to be edited is highlighted and can be selected by
pressing Enter, double-clicking on the line, or selecting the Edit Line function from the
menubar. Selecting an input for editing will produce the dialog box for that input type.
After an input or output port has been configured, it can be activated in the Points section for
alarm reporting, monitoring or control purposes. Input ports can be changed to one of the
other types by selecting from the Change Input Port drop-down list. Changing the input type
will force any variables used in the Hardware section to the default value and will remove any
points that make use of this port. Output ports can be changed from one type to the other.
Digital Input
A Digital input represents the basic input type, responding to either high or low signals to
indicate the status of the port. Wiring of the port determines if ground closure or voltage
signals are being monitored.
Debounce times are set to qualify the state of the input before it is considered valid. Two
debounce time ranges, seconds and minutes, are available. The seconds range has a
maximum value of 1638 seconds (27 minutes) with a resolution of 25 msec. For longer
debounce times the minutes range should be used. When set to minutes, the debounce
timer has a maximum value of 65,535 minutes with a resolution of one minute. For short
