After powering up the SR4 will only loop the files that are located in the root directory, not the ones
inside the file folder. The files inside the file folder can be triggered using the input OR IN6.
HOW TO NAME A FILE FOLDER AND TO NAME THE AUDIO/VIDEO FILE:
USE simple letters only and DO NOT use any space in the file name. The SR4 will not play if a file
has a space in its name.
Example:
Big Bird.ts. This file will not play because of the space between Big and Bird. To play, change it to
Big_Bird.ts (no space).
Bad dog.ts. This file will not play (space between Bad and Dog).
Bad_dog.ts. This file will play (no space in it's name).
The file folder name does not matter since the SR4 will recognize it as a file folder. However it is a
good idea to name it using 8 characters or less. Copy the audio/video files that you want to play using
the SR4 digital input into this folder. You do not have to re-name the audio/video files. Remember DO
NOT USE MAC to copy these files.
SR4 INPUT:
The SR4 has 5 inputs that can be used to play a audio/video file. These inputs are configured as
binary. The 5 inputs are IN1, IN2, IN4, IN8 and IN16.
HOW to trigger an INPUT:
To trigger input 1,2,4,8,or 16, 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.
To trigger input 9, short both 1 and 8 momentarily to ground.
To trigger input 10, short both 2 and 8 momentarily to ground.
To trigger input 12, short both 4 and 8 momentarily to ground.
To trigger input 17, short both 1 and 16 momentarily to ground.
To trigger input 18, short both 2 and 16 momentarily to ground.
To trigger input 20, short both 4 and 16 momentarily to ground.
To trigger input 24, short both 8 and 16 momentarily to ground.
The above single and 2 input combination (total 15 inputs) can be triggered directly using the push
button that is available from our web site. To trigger 3 or more input combination at once, you have
to use a diode network.
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 SR4 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 SR4 input. Use this to test your play list program.
Example:
To trigger SR4's input 1, press key 1.
To trigger SR4's input 2, press key 2.
To trigger SR4's input 16, press keys 1 and 6.
