STEL-1209 EVALUATION BOARD SOFTWARE INTERFACE USER’S GUIDE
This Windows 95™ based software package is designed
to make programming and debugging the operation of
the STEL-1109 ASIC as easy as possible. It allows the
desired configuration to be derived while working at a
high level, eliminating the need to program the STEL-
1109 at the register level. In addition, it gives the user
the flexibility to select programmable features and
settings in connection with our upstream demodulator;
the STEL-9244. However, it is still necessary to have a
good understanding of the capability of both the STEL-
1209 and the STEL-1109 to be able to use this software
tool effectively. Standard Windows 95 procedures are
used in operating the menus and controls. Many of the
buttons require only a single click to activate.
Remember to press the Enter key for those buttons that
require numerical or keyboard entry.
Enter key is essential for proper operation of the STEL-
1209 board.
To install the software, run the program named,
"a:\setup" and follow the instructions given on the
screen.
When the software is started, a window will be opened
with the default parameter settings. These parameters
are also loaded into the STEL-1109 and the Burst
Controller FPGA on the STEL-1209 board on power-up.
The window incorporates a Menu Bar, three soft
buttons, and a parameter entry area with bit mapped
graphics near the top that resemble three folder tabs.
Menu Bar Items
The menu bar is displayed at the top of the window
and contains three menu items: File, View Registers,
and Windows.
FILE:
Under the File menu the following items can be
accessed:
Save Parameters As - Saves the active window with its
parameter settings for future use as a new file.
Save Parameters - Saves the active window with its
parameter settings for future use, overwriting the
previous values of the file with this name.
Load Parameters - Opens previously saved file with its
parameter settings.
View Parameters - looking at contents of saved
parameters in a text file format.

Pressing the
10
Load User File - Opens an ASCII hex/character format
user supplied data file (text) for use as the input data
source. This allows the user to transmit a fixed known
data pattern. The user can load either ASCII hex or
ASCII character (or both) formats within a single file
such as the USERFILE.txt file comes with the GUI
software installation disks. In burst mode, the data file
contains both the preamble and the data information
with preamble being loaded first and followed by the
data.
Exit - Causes the program to terminate.
VIEW REGISTERS:
This gives the user the capability to access both the
write and the read registers of STEL-1109 ASIC.
Read Registers - When this item is selected, a new
window showing the STEL-1109 read registers is
opened. Each individual register value can be read
from the board by hitting the <Enter> key at each
register box. To read all register values at once, click
the Query Registers command button.
Write Registers - When this item is selected, a new
window showing the STEL-1109 write registers is
opened. Each individual register can be programmed
by entering a new value and then hitting the <Enter>
key.
Configure command button.
WINDOWS:
This is a standard window menu.
The Parameter Entry Area:
There are three screens to the Parameter Entry area.
Each one of these screens can be accessed simply by
clicking on the left mouse button once the cursor is
positioned on the desired "folder tab". These folder
tabs are labeled Main Parameters, Scrambler and FEC,
and Filters; located at top of the screen. All the fields
in the three taps can be individually downloaded by
clicking an event choice or changing a value and
pressing the <Enter> key. All the changes made on the
three tabs will be updated in the Write Registers
window, but not vice versa.
The Main Parameters screen is shown in the following
page. The TAB key moves the cursor from field to field.
To write all register values at once, click the
