APP APP-601 - Introduction and Driver Window

Using the APP Driver 7-2
7.1 Introduction to the APP Driver
The APP Recorder Driver is the program that manages the physical APP Recorder hardware. You can
access the APP Driver from within the APP Recorder program.
In the APP Driver, you can view communications between the following items:
 The APP Recorder and the APP Driver
 The APP Driver and all the system DSP circuit boards
 The computer control chassis and all the data chassis
7.2 Viewing the APP Recorder Driver Window
 To View the APP Recorder Driver Window
From the APP Recorder window, open the File menu, and click Show Driver.
The APP Recorder Driver window appears.
Figure 57: The APP Recorder Driver Window
The Information area contains the following fields:
 Time Mark
This field displays the absolute times of the 1PPS signal for all the DSP boards. The times are
updated every 30 seconds. If multiple times are displayed, meaning that there are two or more
DSP boards, they should be the same.
 #Packet (Ex)
If extended recoding is enabled, then you can see packet transfers (or data flow) from the DSP
circuit boards to the computer hard drive.
 #Recovery (Ex)
If the extended recording feature is enabled in the Point Assignment Record (General Settings
tab: Sampling tab), then this area will display a running total of the number of times packets had
to be re-sent from the DSP board to the computer hard drive.
 (>65C, C)
The temperatures of the DSP boards are displayed here. In a normal situation, the display may
look something like (0, 45C). The zero indicates that the DSP temperature is below 65C and it is
now 45C. If the temperature on the board is over 65C, the zero will become one. Because the
indicator (0 or 1) is sensed differently than the reading, you can trust that the temperature reading
is correct.
