Sounding Board (tm) adapter Test Procedure
___________________________________________
The Sounding Board (tm) adapter can be tested by running
either a handset test called HTEST.EXE, or a Line-In and
Line-Out test called LTEST.EXE. Both of these tests re-
quire the Sound adapter to be used in full-duplex mode,
i.e. using both DMA channels 1 and 3. If you intend to use
the board in half-duplex mode only, then use SAY.EXE AND
RECORD.EXE to separately play and record messages to verify
that the adapter is working.
Testing the Sound adapter in full-duplex mode:
-------------------------------------------
You will need a standard phono plug to phono plug cable to
perform the Line-In and Line-Out test, and you will also need
to test the handset provided.
For running either of the tests verify the following:
1. Jumpers J1 and J2 are both in the ON position on the
Sound adapter. This selects the use of both DMA channels
1 and 3.
2. The SOUNDBD.EXE driver is installed using both DMA
channels.
To run the handset test:
-----------------------
1. Plug the handset into the RJ-11 jack on the Sound adapter.
Place the handset on a smooth, flat surface such that the
mouthpiece and speaker are facing downward. This provides
an acoustical coupling between the microphone and speaker.
2. Run the HTEST.EXE program. You should hear an audible beep
and then a message will appear indicating the result of the
test. A "Handset passed" message will be shown if the
test passed. If any other message appears, verify that the
handset is positioned correctly and that it was not bumped
during the test. Run the HTEST.EXE program again to verify
the results.
Running the Line-In and Line-Out test:
-------------------------------------
1. Remove the handset from the jack on the Sound adapter.
Insert the phono plugs, one side into Line-In and the other
side into Line-Out.
2. Run the LTEST.EXE program. The result of the test will
immediately appear. A "Line-In and Line-Out passed"
message will be shown if the adapter passed. If any other
message appears verify that the cable is plugged in
correctly and run the LTEST.EXE program again.
Testing the Sound adapter in half_duplex mode:
---------------------------------------------
Verify the following before testing:
1. Place either J1 or J2 in the ON position depending on
whether you are using DMA channel 1 or 3 respectively.
2. The SOUNDBD.EXE is installed specifying which DMA
channel is in use.
The RECORD.EXE program is used to record a message through both
the handset and the Line-In jack to a file. The syntax for using
the program is:
RECORD[option] filename
where "option" represents the optional switch /C if you want to
enable 2-to-1 compression on the file and filename represents the
name of the file to record data into. Press any key to abort the
program.
The SAY.EXE program is used to play a message from a file to the
handset and to the Line-Out jack. The correct syntax is:
SAY[option] filename
where "option" represents the optional switch /C if the file was
recorded with compression and filename represents the name of
the file to be played. Press any key to abort the program.
Once you've successfully recorded and played a message, the Sound
adapter is fully tested.
Note: You can also run the RECORD.EXE and SAY.EXE programs when using
the Sound adapter in full-duplex mode.
