Generator. This board plugs right into the ISA bus inside of your PC. On the back of the board is a
standard VGA connector that connects to the monitor.
3.6 Altering the Default Serial Port Assignments
By now you should see that the different combinations of monitors and generators could cause havoc
with the RS-232 serial ports at the back of your PC. Here is a summary of the default requirements :

3.6.1 Altering The Default Comm Port
Depending on your exact needs, you can change these default ports by using DOS 'Environment Strings'.
These strings can be entered by you on the DOS command line or put into your autoexec.bat file. The
format of the command to create one of these strings is:
set string = #
In place of the word 'string' use one of these names depending on the device that you want to reassign:
SIGGENPORT VG-819(S), VG-823, QD801GF, QD801GF-ISA
N1PORT For all X2R/N2/N2H/24W1 Monitors
For the monitors, the VG-819(S), the VG-823, and the QD801GF:
In place of the '#' sign in the 'set' command, enter a number from 1 to 8 which identifies which serial port
that device is connected to:
# Port Port Address(Hex) Monitor
1 COM1 3F8 All
2 COM2 2F8 All
3 COM3 3E8 All
4 COM4 2E8 All
5 COM5 320 N1PORT only
6 COM6 328 N1PORT only
7 COM7 338 N1PORT only
8 COM8 280 N1PORT only

COM1 and COM2 are the standard two serial ports found in most PC's. COM3 and COM4 can usually
be added to the PC with the addition of an I/O Expansion Board. The remaining ports are for special
boards that use non-standard port addresses implemented on combination RS232 boards.
For the QD801GF-ISA:
In place of the '#' sign in the 'set' command, enter a number from 1 to 8 which identifies which jumper
setting is made on the QD801GF-ISA card:
# ISA Port Address(Hex)
1 0 300
2 1 308
3 2 310
4 3 318
5 4 250
6 5 258
7 6 260
8 7 268
Here is an excerpt from the Quantum Data Model 801GF-ISA Quick Start Guide :
Prepare the card for your correct ISA or base I/O address.
This is done by placing the provided jumpers in the pattern for your ISA or
I/O shown in this table. The card comes with a default setting of ISA 0
Jumper
Locations
There are two other jumper positions:
X and M. Position X is empty and M
always has a jumper.

(base I/O 300H).
Base I/O
Figure 1: QD801GF-ISA Jumper Setting
Page 9
Digital Alignment System INY Corporation P.E.
After you have entered one of these 'set' command, you can check what the PC thinks you typed by
entering the 'set' command without anything following it:
set
Here is what 'set' commands would look like for the default port assignments (you don't have to use
these commands if the defaults are correct for your case):
set N1PORT=2
set SIGGENPORT=3
Now, for example, say you have a machine without a mouse. You can connect the VG-819 to COM1
and the monitor to COM2 by issuing these commands before you run the DAS program:
set N1PORT=2
set SIGGENPORT=1
The first one isn't actually needed anyway since it is the default port.
3.6.2 Altering The Default Interrupt Number
Usually the only way to use a different interrupt number is to change the default COM port assignment.
In most cases, the interrupt number is fixed to the COM port as follows:
Comm Port Interrupt Number
COM1 4
COM2 3
COM3 4
COM4 3
COM5-8 varies
Bus Mouse varies
Generally on a PC, the available interrupts for ports and mice are 2, 3, 4, 5, 7, 10, 11, and 12. On some
PC’s sound cards or other devices may already use some of these. Check your device documentation for
the best combination.
If you can, you should have the bus mouse use interrupt 10, 11 or 12. Then interrupts 3 and 4 are both
available for DAS devices.

Digital Alignment System INY Corporation P.E.
4 Error and Warning Screens
We think the Error and Warning Screens that you may see are very important. So important, in fact, that
we put this section of the User's Manual near the front.
The DAS program is designed to operate in as user friendly a manner as possible. The screens we display
may help you to get the program running correctly without having to get technical help.
There are five types of errors:
1. Communications errors
2. Monitor mode and frequency selection errors
3. Model information and errors
4. Disk Not Ready
5. Critical Disk Error
There are two types of warnings:
1. Horizontal frequency determination inaccurate
2. Signal Generator not set correctly
4.1 Error Type 1
When communicating with the monitor and signal generator, the program will try several times before
indicating a failure. If the program cannot establish communication, it will put up a screen (Screen 2 and
Screen 3) asking you if you want the program to try again.
Page 11
Digital Alignment System INY Corporation P.E.
Screen 2: Monitor Retry Popup
This screen (Screen 2) shows a monitor communications problem. At this point, you should check that
the RS-232 board and monitor cables are correctly installed (correct port, etc.). Press [YES] to have the
program try again. Press [NO] to return to the main screen. You should always press [YES] once or
twice before you give up. If the DAS cannot establish communications with the monitor, you may have a
defective monitor, RS-232 board or cable.
Page 12
Digital Alignment System INY Corporation P.E.
Screen 3: Signal Generator Retry Popup
This screen (Screen 3) shows a signal generator communications problem. At this point, you should
check that your serial board and signal generator cable are correctly installed. If you are using an Astro
Design VG-819(S), make sure you have wired the cable as shown in Section 3.5.1. Press [YES] to
have the program try again. Press [NO] to return to the main screen. You should always press [YES]
once or twice before you give up. If the DAS cannot establish communications with the signal generator,
you may have a defective signal generator, RS-232 serial board or cable.
Page 13
Digital Alignment System INY Corporation P.E.
4.2 Error Type 2
There are cases where the internal horizontal frequency determination logic may not select the correct
mode within the monitor. This may have an external cause, such as an incorrectly setup signal
generator or an internal cause, such as the accuracy of the Timer/Counter inside of the monitor. If this
occurs, a screen (Screen 4) will display what was expected and what was actually determined. Check the
generator to be sure that it is setup correct. Check the cables to be sure they are wired correctly and
plugged in to the correct connectors. Correct it if necessary and then select [YES] to retry the operation.
If you are not using a manual generator, the problem is within the monitor. In this case contact technical
support.
If you are using a VG-819 generator, there is an additional possible cause for this error. The VG-819
cannot turn off its Sync outputs and will have cases where sync information is contained on the green
output BNC as well as the CS, HS and/or VS output BNC's. If you use the 819, you may have to
disconnect the Horizontal and Vertical Sync cables if adjusting "Sync on Green" modes.
Screen 4: Mode Selection Error
Page 14

There are also cases where the accuracy of the basic frequency determination logic in the monitor
prevents the monitor from determining the exact input horizontal frequency. This is not a problem as
long as the monitor determines the correct mode. An informational screen (Screen 5) will be displayed to
tell you what happened. Press [OK] to continue the adjustment.
The DAS program is looking for 1) correct mode selected and 2) correct horizontal frequency. If the
mode is correctly selected, proceed with adjustment.
Screen 5: Frequency Determination Error
4.3 Error Type 3
If the DAS model information contained in its internal data base becomes corrupted, you will get an
error indicating a "Data Base" error. If this occurs you should reinstall the software following the
procedure in Section 6.
If the problem persists, copy down the error message and contact technical support.

4.4 Error Type 4
When you are using a diskette for reading or writing EEPROM files, if there is no diskette in the drive,
you will see this screen (Screen 6).
Press the Enter key to retry the operation after inserting the diskette in the drive. Press the Esc key to
cancel the operation. You may want to cancel the operation if, for example, you tried to access disk drive
A: when, in fact, you wanted to access disk drive B:.
If this error repeats when you believe it should not, you may have a hardware problem.

4.5 Error Type 5
When you are using a diskette for writing EEPROM files, if the diskette in the drive is write protected,
you will see this screen (Screen 7).
Press the Enter key to retry the operation after removing the write protect tab from the diskette. Press
the Esc key to cancel the operation. You may want to cancel the operation if, for example, you had the
wrong diskette in the drive.
If this error repeats when you believe it should not, you may have a hardware problem.
Screen 7: Critical Disk Error
4.6 Warning Type 1
Each time the monitor switches modes, the DAS program reads the horizontal frequency register and
checks its value. The program does this to be sure that the signal generator has been setup correctly. The
accuracy of the frequency measurement in the monitor may cause a warning message to popup on the
screen (Screen 5) at this point. The accuracy, according to the monitor specification, is plus/minus 5
microseconds of 255 horizontal periods. The monitor itself has a resolution of plus/minus 100 Hertz. The
DAS program will warn you that the monitor has determined a different frequency than what was
expected. It is a warning only. Press the [OK] button to have the program continue.
This check is performed in the Factory Presets screen of the DAS program.

4.7 Warning Type 2
If you are connected to a supported signal generator, the DAS program will automatically control the
setting of the generator. Part of this process is to make sure that the signal generator is operating
correctly. To do this, the DAS program will double check the generator after programming it for the
selected mode. If the generator does not confirm that it is correctly set, you will see a warning screen
(Screen 8). It is a warning only. Press the [OK] button to the have program continue.
