TASCAM HD-R1 255–Parallel InterfaceIn direct play mode, input pins 1 though 16 controlplayback of the currently loaded playlist’s first 16tracks, respectively. The exact playback behavior canbe customized on a per-track basis using the playlisttrack settings found in each playlist entry menu underthe Parallel Control submenu. (Please referto the Edit Playlist section of this document.)The following descriptions assume that the inputsignal is active when a button is pressed.If Playback Mode is not set to Playlist,the first 16 tracks, as determined by the currentPlayback Mode, will be triggered in themanner determined by the settings found under MainMenu ˘ System Settings ˘ PlaylistDefaults ˘ Interruptible.NOTEDirect Play operates by SINGLE playback mode.Direct playBinary playProgram playBinary play mode works exactly like direct playmode, except that input pins 1-10 are interpreted asa binary number. This enables the triggering of upto 1023 different tracks. In the idle state, the signalsfed into pins 1-10 must be inactive as determined`byMain Menu ˘ System Settings ˘Parallel Port ˘ Input Polarity. Ifany of the signals change state, the HD-R1 will waituntil all 10 signals have been stable for 250 ms beforecapturing their state to yield a binary number. Anactive signal is interpreted as a binary “1”. This binarynumber will designate the track that is to be played.NOTEBinary Play operates by SINGLE playback mode.Program play simply provides a way to control thetransport keys via the parallel port. It functions withany Playback Mode. An active signal on pin13 is equivalent to pressing the PLAY key. An activesignal on pins 14 or 15 is equivalent to pressing SKIP≤ or SKIP μ keys, respectively. An active signalon pin 12 will change to the previous folder/playlistin alphabetical order. An active signal on pin 16 willchange to the next folder/playlist in alphabetical order.An active signal on pin 17 is the same as pressingSTOP.
