1. Line Output LINE 1 8 Stereo Phone Jack This jack provides a single ended output for external amplification when the application calls for more power than the internal power amplify can deliver This output can also be used to power a headphone directly Volume Knob VOL Turn the knob clockwise to increase the output volume It affects both the speaker output and the line output Balance Knob BAL Use this knob to get unequal amount of output from the left and the right channels Speaker Output Terminals LF left channel amp RT right channel The speaker outputs are single ended unbalanced Depending on the ambient tempera ture additional heat ventilation may be required to obtain maximum output If the built in power amplifier is not to be used it can be disabled by moving the internal jumper J1 to the OFF position in order to save power Relay Output Terminals for EM3034A R amp EM3034A X only Three terminals are provided for each relay NC Normally Closed NO Normally Open and Common the center terminal The contacts are rated at 10A 24VDC 120VAC Typical wiring diagram for push button applications 0004 NC4 NO NC3 NO NC 2 NO NC 1 N RELAY OUTPUTS FOR R amp X VERSIONS DRAWING IS NOT TO SCALE PWR LIGHT VD GD RS T1 T2 T3 T4 UNBALANCED LINE OUT TO EXTERNAL POWER AMP EM3034A EM3034A R EM3034A X User s Manual Page 2 of 4 Trigger Modes The Trigger Mode defines2. s connected to the ground Break Contact The input is triggered once when it s disconnected from the ground System Configuration File By default the system works in the following mode Direct Trigger Non Interruptible Playback Close Contact To operate the system in other modes you need to create a plain text file called MODE TXT with a line of three letters First Letter Trigger Mode D Direct S Sequential R Round Robin Second Letter Playback Mode N Non interruptible Interruptible H Holdable S Script Third Letter Contact Mode C or no letter Close Contact O Open Contact M Make Contact B Break Contact For Script modes enter the script starting from the second line Be sure to add the word END at the end of the Script After editing the configuration file be sure to save it as a plain text file ASCII text file or simply text file The system may not work if the configuration file is not created properly Modes with Special Notes DHM SHM RHM When the contact makes the file starts to play for as long as the contact stays closed but will not loop DHB SHB RHB When the contact breaks the file starts to play for as long as the contact stays open but will not loop SIC SIO In these modes an input can be interrupted by other inputs but not by itself If an input needs to be interruptible by itself use either the SIM or the SIB mode
3. EM3034A EM3034A R EM3034A X User s Manual Page 3 of 4 Script Playback Mode Instead of playing just a single file Script Playback mode executes a script of commands for each trigger Written in the configuration file using plain ASCII text there are multiple scripts each containing the commands for a particular trig ger in the following format nnn Command1 Commandz2 Here nnn is the trigger number and is one of the following N Non interruptible Execution of this script is not interruptible l Interruptible Execution of this script can be interrupted by another trigger H Holdable Execution of this script continues for as long as the trigger is ac tive repeating itself if necessary The execution stops immediately when the trigger is no longer active For the Direct Script and the Round robin Sript modes there are 4 direct scripts 001 004 corresponding to T1 T4 For the Se quential Script mode there are 396 direct scripts 001 099 for T1 200 299 for T2 300 399 for T3 and 400 499 for T4 In addition to the direct scripts there are also indirect scripts An indirect script can be activated only by jumping from another script using the Jump command The following are the script commands Fnnn play File nnn Example F168 plays file 168 Wnnnnn wait nnnnn units of 0 1 second Maximum value for nnnnn is 65535 6553 5 seconds Example W00020 wait 2 seconds Note
4. 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 configuration file c If the flash card is inserted when the power is on the system may not work To fix this problem turn the power off for a few seconds to reset the system Some CF cards especially if they have been used in digital cameras need to be reformatted with the FAT16 file system The output volume may have been set too low Try turning it up Q Plays a wrong File File numbers are not assigned properly The system is in the wrong mode due to missing or incorrect configuration file OM NH OO 3 Plays trashy sounds It s probably due to unsupported file formats such as 8 bit resolu tion or ADPCM coding Re digitize or convert the file into a sup ported format 4 Playback speed is too slow fast Unsupported sampling rates may result in wrong playback speed Re digitize or convert the file into a supported sampling rate 5 Plays a popping bursting noise once in a while The speed of the flash card is too slow Use a faster flash card or convert the file to a lower sampling rate

6. priority prevails Round Robin Trigger This mode is very similar to the Direct Trigger mode except that the inputs are not prioritized So if multiple inputs are tied to ground then their files will be played one after another instead of just the highest priority one Round Robin mode can only be used in con junction with Non interruptible Playback and Script Playback Playback Modes Non interruptible Playback default The file is played once per trigger The playback is not interruptible except by the system reset Looping is possible by applying a con stant trigger on the input Interruptible Playback The file is played once per trigger if not interrupted Any input in cluding itself can interrupt the playback later Looping is possible by applying a constant trigger on the input Holdable Playback The file is played for as long as the input is triggered looping if necessary It is not interruptible except by the system reset When the Holdable Playback is used along with the Sequential Trigger it will repeat the same file instead of advancing to the next file if the trigger extends beyond the end of file Script Playback Please see the Script Playback Mode section for descriptions Parallel Trigger Polarity Close Contact The input is constantly triggered when it s at OV ground Open Contact The input is constantly triggered when it s at 5V open Make Contact The input is triggered once when it

9. how the playback is to be triggered All trigger inputs are internally pulled up through 10K resistors Inputs are 3 3V CMOS logic but 5V tolerant If left unconnected an input is at 3 3V logic 1 Direct Trigger default In this mode each input directly triggers a corresponding file T1 File 001 T2 File 002 T3 File 003 T4 File 004 The Direct Trigger is prioritized from T1 the highest to T4 the lowest However it does not mean a higher priority input can inter rupt a lower one It only means that if multiple triggers are applied at the same time the highest priority prevails Sequential Trigger Use the Sequential Trigger to sequentially trigger up to 99 different files per input as defined below T1 triggers File 001 099 T2 triggers File 201 299 T3 triggers File 301 399 T4 triggers File 401 499 Each trigger on the same input activates the next file in the se quence The sequence automatically restarts when either the end of the sequence is reached or there is a break in the sequence For example if there are only three files on the flash card 001 002 and 004 the system will only sequence from 001 to 002 File 004 will never be played because File 003 is missing The Sequential Trigger is prioritized from T1 the highest to T4 the lowest However it does not mean a higher priority input can interrupt a lower one It only means that if multiple triggers are applied at the same time the highest
