1. Fourth letter in MODE TXT By default the left channel is inverted If using a MONO audio file this creates a 4X more powerful differential output when a 8 ohm speaker is connected to the LEFT and RIGHT outputs from the TecMP3 To switch the audio back to REGULAR mode enter R as the fourth letter RS232 Serial Control For serial control RS 232 RS 485 replace the two letter word in MODE TXT with a two digit address ranging from 00 to 32 This number is used by your PC or controller to communicate with specific TecMP3s RS232 Commands C Closed Keep triggering when contact closed O Open Trigger when contact opened M Make Trigger once when closed B Break Trigger once when opened Ad address send before every command if the player ID is not 00 FH play file L loop file S Stop file P Pause file R Resume file B busy enquiry b is busy and s is not XN turn on relay XNN turn on all relays XF turn off relay XFF turn off all relays FULL USER MANUAL ALSO AVAILABLE ONLINE www technovision com manuals html2. switches the left channel back to Regular audio mode see next page For example DN is Direct trigger mode and Non interruptible Other modes are DI Direct Interruptible DH Direct Holdable DS Direct Script BN Binary Non interruptible BI Binary Interruptible BH Binary Holdable BS Binary Script SN Sequential Non interruptible SI Sequential Interruptible SH Sequential Holdable RN Round Robin Non interruptible RS Round Robin Script Trigger Modes first letter in MODE TXT Playback Modes second letter in MODE TXT D Direct Trigger most popular In this mode each input directly triggers a corresponding file T1 File 001 T2 File 002 T8 File 008 A trigger is valid when the input is shorted to the ground for at least 50 ms S Sequential Trigger Use the Sequential Trigger to sequentially trigger up to 99 different files per input as defined below T1 triggers File 001 002 099 001 002 T2 triggers File 201 202 299 201 202 T3 triggers File 301 302 399 301 302 T8 triggers File 801 802 899 801 802 Each trigger on the same input activates the next file in the sequence until it does not find a file It will then sequence back to the first file B Binary Trigger To trigger a particular file the first step is to signal the file number on T1 LSB T7 MSB and T8 being the data latch R Round Robin Trigger This mode is very s
