RS-232/Contact Closure Controllable Digital Audio Player
USER MANUAL
010601
Introduction
iOS is an RS-232/contact closure controllable digital audio player. Fifty RS-232
controllable presets, the ability to store a total of two, four or eight minutes of
audio clips (depending on the model) and contact closures allowing 4 presets to
be trigger, make iOS suitable for multiple applications. Voice prompting, ringer
for audio/video conference systems, product displays and voice alert for
security are just a few examples of its flexibility. The versatility of the iOS will
enhance any system it is interfaced with.

P.1
Interconnects:
1) Before using the iOS Studio program make sure the iOS unit is connected to
your PC sound card. The headphone or line output of the PC goes to the iOS
unit’s input (Rec In). You’ll need to use a 1/8”stereo (TRS) audio cable.
To allow monitoring of your recorded files, connect the iOS Line Out to an
amplified speaker or sound system.
Tip: You can also use your PC’s sound card Line In to monitor your iOS
recordings.
2) You also need to connect a serial cable* from the iOS unit’s RS-232 port to
one of the serial ports of your PC.
*IMPORTANT: Make certain that the serial cable only uses 3 conductors
(pins 2,3,5) connected straight through (pin2 to 2 , 3 to 3, 5 to 5) for a 9-pin
connector. If you’re using the 25-pin on your PC the pin out from the 25-pin to
the 9-pin is is 3 to 2, 2 to3, and 7 to 5.
The RS-232 port on the iOS uses pins 6-9 as contact closure triggers for
presets 1-4. By closing one of these pins to gnd (pin 5), the appropriate preset
will play. The preset will stop when it reaches the end. If the contact closure is
left closed the preset will repeat itself in an endless loop. This feature can be
handy in some applications.
P.2
Rear View
The RS-232 port is used to control
the iOS unit. Connect the serial
cable (pins 2,3,5) or contact closure
(pin 5 is gnd, pins 6, 7, 8, & 9 are
contacts.)
The 6V DC input is
used for powering the
iOS unit. Use the
supplied power supply.
The Line Out is the
audio output of the unit.
Connect this to an
amplified audio system.

Getting Started:
The iOS Studio is a program designed to be used with the iOS unit. With it, you
can play .wav files and transmit code out the RS-232 port of a Windows based
PC. It is similar to a regular Windows media player except it has a place to
enter a preset number that determines which preset in the iOS unit is to be
recorded. Code is sent out when the PLAY, STOP and RECORD buttons are
selected.
Programming Sounds into the iOS:
Start iOS Studio and click on the Serial Port item in the SETUP menu.
Set the appropriate COM port item. The baud rate is currently fixed at 9600
baud.
Tip: It is highly recommended that you create an IOS playlist. This simplifies
.wav file management and maintains the preset order of your project.
1) To make a playlist, click on the NEW PLAYLIST item in the TOOLS menu.
This will bring up the playlist dialog box. Enter a playlist name in the PlayList
name box. An Edit Playlist box appears as below.

2) If you want to add .wav files from other directories, click the BROWSE
button to select alternate locations. Note that the directories can be located
on either on your local machine or a network drive; if they are on the network
drive, the drive needs to be mapped to your machine.
3) To add .wav sound files to the playlist, first select from the Wave Files list box
on the left and then click the ADD button; the name will show up in the list box on
the right. Keep adding the files until you have the ones you want. If you want to
delete a file that’s already on the list, highlight it and click the DELETE button.
4) To insert a .wav file at a position in the playlist, first select the file you want to
insert in the list of wave files on the left. Next, select a file in the playlist box.
Then click INSERT. The selected wave file will be inserted before (above) the
selected file in the playlist.
Once you have finished, click on CLOSE.
Selecting a file or playlist to program into the IOS unit:
Go into the FILE menu and click on OPEN. A pop-up window will appear as
below. Select the .IOS file by highlighting it and clicking on the OPEN button.
Preview Section:
Play Button: Clicking on this button plays the sound file selected for previewing
before recording.
Stop Button: Clicking on this button aborts the current sound being played.
Program Section:
Record Button: Clicking on this button activates the iOS unit to record the
sound file selected. If recording an .iOS playlist, a prompt asking to clear all
iOS audio files in the unit will appear. Click Yes to proceed. Then, another
prompt pops up saying,”cleared iOS memory.” Hit OK.
The iOS will now record the audio file.
TIP: Depending on your PC sound card, you may have to record the audio file a
couple of times to get the volume level and sound quality correct.
P.4
We have found that adjusting the volume control on the PC to maximum and
adjusting the iOS Studio Volume Control to 70% records good quality sound
clips.
Play Button: Clicking on this button plays the sound clips recorded in the iOS
unit. You must first enter in a preset number corresponding to the audio clip you
want to hear.
Stop Button: Clicking on this button aborts the recording/playing of the iOS
unit.
Other IOS Studio Screen Elements:
Progress Bar: This shows the amount of the current .wav file that has been
recorded into the iOS unit; it has no meaning in the playback mode.
File Display Bar: This diplays the current file or file list being recorded.
Status Bar: This displays the status of the sound recording and playing.
Volume Control: This slider control adjusts the sound volume to the iOS unit.
Note: Make certain the main audio card volume control is set on your PC, since
this control is secondary.
Memory Indicator Bar: This display element shows the percentage of the
memory used in the iOS unit. A maximum of two, four, or eight minutes is
possible depending in the iOS model.
Note: The memory in the iOS may not match up to the time displayed for the
playlist. The iOS uses between 200-300ms per audio clip for memory
alignment. The amount of time used for memory management depends on how
many files are in your project.
Available record time = 2 minutes - (total # of files * 0.3)
Example: If you have a playlist with 46 files totaling about 108 seconds, it may
not fit into the 120 seconds of the iOS . Worst case, the iOS may need 13.8
seconds of alignment memory causing an overflow message. However, a
single audio clip will get the full two minutes.
P.5
Troubleshooting using IOS Studio:
1) No communication:
Make sure that the iOS unit is powered correctly. You must use the 6V DC
power supply provided with your unit. The green LED on the front of the iOS unit
should be ON.
Verify that the RS-232 cable is connected to the iOS unit and the your PC comm
port. Make sure that the cable is wired correctly. Only pins 2, 3, and 5(gnd)
should be connected.
The baud rate of your port should be set to 9600, N, 8, 1.
2) No audio recorded on the iOS unit:
Make sure that your PC’s volume control is NOT MUTED and that the volume
level is up.
Make sure the iOS Studio’s Volume Control is also up.
Can you here the audio clips out of your PC? If you can, then you are half way
there.
Verify that the iOS unit’s Rec In is connected to the to your PC’s audio line
out/headphone out. You should use an 1/8” TRS (stereo) cable.
Using the iOS Studio, record the audio clips (iOS playlist or .wav file) you’ve
selected. After recording you should see the Memory Bar on the iOS Studio with
a percentage of used memory space.
Verify that the iOS Line Out is connected to an amplified speaker or the audio
Line In of your PC for playback monitoring.
Playback the audio clips from the iOS unit by pressing PLAY in the Program
section of the iOS Studio. Make sure you first select a specific preset number to
be played back.
3) Distorted audio playback from the iOS unit:
As the saying goes, “ Garbage in, garbage out.”
Verify that the original audio clips sound OK. You can do this by listening to the
audio clips out of your PC’s speakers or amplified audio system.
If the original audio clips sound fine, then try re-recording the audio clips into the
iOS at a different Volume Level. It could be too high or even too low. Try until
the audio level and quality sound OK.
