with the Minimum Detection Sensitivity. A typical value for the Average Peak Value Cap
parameter would be 10 db as shown in Figure 9. It is unlikely that this parameter value would
ever need to be any value other than 10 db for each lane.
To save the edited Archive Header File (.hhx) to the \SAS_Monitor_V6\ Arch_Data\ sub-
folder, click the File/Save Archive Header File menu item. Specify the desired file name using
the standard Save File Dialog Window.
Sending the SAS-1 Archive Header Records to the SAS-1
To send a specific archive header file (.hhx) to the SAS-1, click the Sensor/Send Header
Records to SAS menu item in the SAS Monitor and Setup main display. Click the Yes button in
response to the question “You are going to send a new header record to SAS-1…Continue?”.
Select and open the desired file using the standard Windows Open File Dialog Window. This
starts the process of sending the archive header records to the SAS-1. The status of the process
is shown in the status line in the lower left part of the SAS Monitor and Setup main display. If
the process is not successful, the Start/Stop button will show “Stop’. Click the Stop button and
retry the send process by clicking the Sensor/Send Header Records to SAS menu item.
Sending the archive header file (.hhx) to the SAS-1 will reset and clear any existing data in
the SAS-1 archive non-volatile storage space (existing archive data will be lost).
Setting the SAS-1 Date and Time
To set the date and time in the SAS-1, click the Sensor/Set SAS Date and Time menu item.
Click the Yes button in response to the question “You are setting SAS Date and
Time…Continue?”. The status of the process is shown in the status line in the lower left part of
the main SAS Monitor and Setup display.
Setting the SAS-1 Date and Time will reset and clear any existing data in the SAS-1 archive
non-volatile storage space (existing archive data will be lost).
This completes the basic setup for real time SAS-1 operation. It is now ready to be
connected to the Cabinet Controller, SAS Relay Interface, or some other system interface
such as a CDPD modem or network device server.
Collecting the Traffic Data
The SAS-1 has the capability to archive traffic flow measurements for five lanes for up to
several weeks. The amount of archive time depends on the size of the installed non-volatile
memory (1 Mbit, 2 Mbit, or 4 Mbit) and the selected update period (5, 10, 15, 20, 30, or 60
minutes). The SAS-1 continually updates the archive data, independent of its default mode of
