1. Direct Script mode there is only one trigger 001 For the SS Sequential Script mode there can be up to 99 triggers 001 099 to be executed sequentially In addition to the direct triggers there are also indirect triggers An indirect trigger can be activated only by jumping from another trig ger using the Jump command These are the script commands Fnnn play File nnn Example F168 plays file 168 Wnnnnn wait nnnnn units of 0 1 second Example W00020 waits 2 seconds Jnnn jump to trigger nnn Example J007 jumps to trigger 007 XN1 turn on the relay XF1 turn off the relay END Always add the word END at the end of the entire script You may add any comments for your own reference after END Important Notes Script lines must be separated by carriage returns the Enter key A script line is limited to 128 characters excluding and If more space is needed use the Jump command Automatic Execution of Script 000 Upon powerup or reset the system will automatically executes script 000 once if it exists Examples SSM N0O01 F047 XN1 W00030 F899 XF1 J168 H002 F002 H004 F055 1168 F001 W36000 J168 END SSM is not really a script command but it tells the system to enter the Sequential Script Make mode When the input is triggered the system start executing trigger NOO1 Since this trigger is non interruptible it will always executes to the end Trigger N001 is executed a2. Mode section for more details The file number should be added in front of the original filename e g OO1TEST WAV Long file names names longer than 8 let ters or in lower case or with special characters are acceptable but will decrease the maximum number of files that can be stored on the flash card due to FAT16 file system limitation Trigger Input Configuraton The trigger input can be configured to operate in many different ways by adding to the flash card a plain text file called MODE TXT Put three upper case letters in this file according to the following First Letter Input Mode D Direct mode default The trigger always activates file 001 S Sequential mode The trigger sequentially activates one file at a time a list of files starting from 001 The sequence resets to 001 when the next file number is missing For example if there are a total of four sound files on the flash card numbered 001 002 004 and 005 then only 001 and 002 will be played because 003 is missing Second Letter Play Mode N Non interruptible mode default The file plays one time and is not interruptible l Interruptible mode The file plays one time but is interruptible if the input is triggered again However the trigger mode see below must be either M or B in order for the interruptible mode to work H Hold mode The file plays for as long as the input is triggered looping if neces sary and stops as soon as the
3. input is not triggered S Script mode Refer to the Script Mode section for descriptions Third Letter Trigger Mode C Close mode default An input is triggered when it s at OV ground Therefore if an input is tied to the ground through a switch it is triggered for as long as the switch is closed O Open mode An input is triggered when it s at 5V Therefore if an input is tied to the ground through a switch it is triggered for as long as the switch is open because the inputs are internally pulled up to 5V M Make mode An input is triggered when it goes from 5V to OV Therefore if an input is tied to the ground through a switch it is triggered at the very moment when the switch is closed B Break mode An input is triggered when it goes from OV to 5V Therefore if an input is tied to the ground through a switch it is triggered at the very moment when the switch is opened Relay Control The relays are controlled differently in different modes Serial Interface Relays are controlled by serial commands only Refer to the Serial Commands section for details Script modes Relays are controlled by script commands only Refer to the Script Mode section for details All other modes The relay will automatically turn on during playback Trouble Shooting Guide 1 Plays no sound at all a File numbers are not assigned properly b The system is in the wrong mode due to missing or incorrect configur

5. allows you to send and receive data through the PC s serial port Refer to its help menu for more information The first step is to create a text file called MODE TXT on the flash card Put only two letters in the file 66 This will put the player into the Serial mode with an address of 66 You also need to put a test sound file on the flash card named 001 WAV or 001 MP3 The next step is to connect the player to the PC using a proper cable If the PC does not have a RS 485 port install a RS 232 to RS 485 converter Run HyperTerminal and make a new connection with these param eters 9600 baud 8N1 no flow control Now we are ready to send the following commands to the player Player Confirms nothing 290 78 A nothing d nothing S nothing eee playback stopped Note that the ASCII code for the letter B is 66 which is the address we assigned to the player The ASCII code for the letter d is 100 which is the broadcast address we could have also used the ABS command sequence here If you type a wrong letter during the test the player will respond either with a letter e or nothing at all depending on the situation In this case you need to restart the entire session
