•To loop file(s) automatically after powering up OR to play using push
buttons the Compact Flash card requires at least 1 A/V File in the root
(home directory, not in folder), playlist.txt and 1 File Folder.
•The SR6 will automatically loop A/V File (s) in the root after powering up.
The files are sorted alphabetically.
•playlist.txt is a text file that contains the SR6 setup and instruction on how
you want the input (push button) to play the files that are located inside the
file folder(s).
♦File folder(s) contains files that you want to play using the input (push
buttons). These files will not play automatically, it will only play when an
input (push button) is triggered.
Here is a typical content of a CF card if you want to loop file(s) only:

E:\ (this is the CF card)
Bird.mp3 (this is the root directory)
playlist.txt (this is a text file, could be blank)
Test:\ (note: this is a File folder, could be empty)
TEST file folder is required but this folder can be empty.
The content of playlist.txt can be blank but must be present in the root
directory.
Explanation:
SR6 will sort and play the file alphabetically.
After powering up, Bird.mp3 (or any other audio files in the root) will
automatically loop.
Here is a typical content of a Memory card if you want to play file(s) using
push button(s):
F:\
Bird.mp3 (file in the root directory needed for Inputs)
playlist.txt (this is a text file)
Test:\ (note: this is a File folder)
Dog.mp3 (this file will be played by a PB1)
Cat.mp3 (this file will be played by a PB2)
And here is the content of playlist.txt:
010000=Dog.mp3
020000=Cat.mp3

Explanation:
After powering up, the SR6 will automatically loop Bird.mp3.
If input 1 is triggered, Dog.mp3 will play because of this statement:
010000=Dog.mp3.
After playing Dog.mp3, it will return to root to play Bird.mp3.
If input 2 is triggered, Cat.mp3 will play because of this statement:
020000=Cat.mp3.
After playing Cat.mp3, it will return to root to play Bird.mp3.
SR6 INPUT using single and double pole push button:
The SR6 has 3 inputs that can be used to play audio/video file. These inputs are
configured as binary. The 3 inputs are IN1, IN2 and IN4.

HOW to trigger an INPUT:
To trigger input 1,2 and 4 short it momentarily to ground.
To trigger input 3, short both 1 and 2 momentarily to ground.
To trigger input 5, short both 1 and 4 momentarily to ground.
To trigger input 6, short both 2 and 4 momentarily to ground.
The above single and 2 input combination (total 6 inputs) can be triggered directly
using the push button that is available from our web site. The input can be
expandable to 48 inputs using IN6 input board.
How to convert SR6 input into IR MODE (pause.prev,next):
<Use this mode if you want to use NEXT, PREV, PAUSE/PLAY, STOP and
VOL+/- functions using push buttons through the SR6 built in digital input.>
SR6 INPUT using single pole push button and diode:
Note:
Use any small signal diode such as IN4148 etc.

SR6 has a total of 6 built in input. In this mode, these inputs operate as
follows:
IN1 operates as PAUSE/PLAY.
IN2 operates as PREV (previous, lines 60-79 in playlist.txt).
IN4 operates as NEXT (next, lines 60 to 79 in playlist.txt only).
IN3 (IN1+IN2) operates as STOP.
IN5 (IN1+IN4) operates as VOL + (volume up).
IN6 (IN2+IN4) operates as VOL- (volume down).
SR6 in IR mode push button input definition:
To enter IR mode, add this line into the playlist.txt file:
IRMODE=ON (all capital letters only)

In this IR mode, IN2 (previous input) and IN4 (next input) will only play lines
600000 to 990000 in the playl;ist.txt, total of 40 files.
If you want to cycle only 6 files, then add this statement in the playlist.txt:
LOOP=6 (all capital letters only).
This statement will cause the SR6 to play lines 600000 to 650000 using IN2 (prev)
and IN4 (next).
Example:
You want to sequentially play 4 files using a single push button.
Here is the memory card content:
F:\
Bird.mp3 (file in the root directory needed for Inputs)
playlist.txt (this is a text file)
Test:\ (note: this is a File folder)
Dog.mp3
Cat.mp3
Lion.mp3
Tiger.mp3
And here is the content of playlist.txt:
IRMODE=ON
LOOP=4
600000=Dog.mp3
610000=Cat.mp3
620000=Lion.mp3
630000=Tiger.mp3
Sample of playlist.txt:

Explanation:
After powering up, the SR6 will automatically loop Bird.mp3.
If input 4 (Next input) is triggered, Dog.mp3 will play because of this statement:
600000=Dog.mp3
After playing Dog.mp3, SR6 will return to home position and loop.
If input 4 is triggered again, Cat.mp3 will play because of this statement:
610000=Cat.mp3.
After playing Cat.mp3, SR6 will return to home position and loop.
After playing the last file Tiger.mp3, the SR6 will be ready to play Dog.mp3 again.
HAND HELD IR UNIT :
The Hand held IR unit is identical to a DVD remote control. It has functions
similar to a DVD such as Forward, Rev, Step, Pause, Stop, A-B etc. The IR hand
held unit can also be used to bring up the Main Menu. Use the arrow UP/Down and
Left/Right keys to navigate the menu. From this main menu you can access and
modify SR6 settings. From the main menu you can change various Audio setting,
Audio/video setting and other preferences.
Please note that the play list will override this setting after powering up.
The Hand held IR unit can be used to trigger SR6 input. Use this to test your play
list program.
Example:
To trigger SR6’s input 1, press key 1.
To trigger SR6’s input 2, press key 2.
To trigger SR6’s input 16, press keys 1 and 6.
PLAYLIST:
playlist.txt: (do not use MAC to create this)
NOTE: name playlist.txt using lower case letters. Do not use capital letters.
This file is required only if you want to play video using push buttons.
The playlist.txt is a file that relates (lists) video files to certain inputs. The purpose
of this playlist is to create “software input” so that each file can be associated with
“an input”. Create playlist.txt using any text editor such as Notepad, Wordpad etc.
If using NOTEPAD, save the file as follows:
Use your cursor and Go to FILE
Go to SAVE AS
Choose the location on your hard drive
In the File name column type lower case only: playlist
Important: DO NOT type playlist.txt, type playlist only
All letters in lower case only.
Save as type: Text Documents (*.txt)
Encoding: ANSI and save the file.
