PLAY NEXT: Switch #7 enables the Play Next sequential playback mode. If Play Next is ENABLED, only the
Message #8 input is active. Successive momentary closures will play active messages in sequence, from lowest to
highest, then repeat. This mode can be used for automatic 'rotation' of messages.

Play Next mode is disabled.

Play Next mode is ENABLED.
NOTE: CONFIG switches will NOT affect operation when messages are played using the local START/STOP
button. CONFIG switches affect play mode only when message playback is triggered via GPI remote control (P1).
MEMORY PROTECT: Switch #8 allows the user to "lock out" the record mode so that messages cannot be
recorded, erased, or changed.

5.0 LOCAL OPERATON: Recording and playing messages using the pushbuttons on the unit.
(NOTE: CONFIG switches described above do NOT affect operation via these pushbuttons.)
5.1 RECORDING A MESSAGE (NOTE: The minimum message length is 2 seconds.)
1. Make necessary audio input and output connections to the system. Set OUTPUT LEVEL fully CW.
2. Push the RECORD SETUP button; Record LED will flash.*
3. Press the SELECT button to select the Message # to be recorded.
4. Feed audio into the DigiStor-MP while watching the AUDIO SENSE and OVERDRIVE LEDs. The AUDIO
SENSE LED should light to confirm audio is present. If the OVERDRIVE LED flashes, the input level it too high.
Turn the INPUT LEVEL control CCW until it goes out. (Audio signal will be heard through the OUTPUT jacks.)
5. Once audio levels have been set, begin recording by pressing the START/STOP button once. The RECORD
LED will remain ON during recording. NOTE: There is a slight delay, about ½ sec, before recording begins.
6. To stop recording, press the START/STOP button again. System will return to idle.
* Record Setup will time-out after 1 minute of inactivity.
5.1.1 RECORDING A “SYNC” RELAY CUE: DigiStor-MP can be programmed to generate a momentary relay
closure at the SYNC relay outputs while any message is playing. To manually “mark” the position where the SYNC
relay should close during playback, press the SYNC button while recording a message. As the message plays,
the SYNC LED will light when a SYNC cue is detected and the SYNC relay closes.
An alternate way to record a SYNC cue during recording is to feed a 1kHz tone into the SYNC INPUT jack. A
SYNC cue will be recorded when this tone is sensed.
5.2 PLAYING A MESSAGE: (NOTE: CONFIG switches do NOT affect play via pushbuttons on unit.)
1. Press the SELECT button to select Message # to play.*
2. Press the START/STOP button to begin playback.
3. Press the START/STOP button again to stop playback at any time.
* Playback message selection will time-out after 1 minute of inactivity.
6.0 REMOTE OPERATION USING GPI INTERFACE: DigiStor-MP can be controlled via GPI (contact closure)
interface. GPI control allows access to Message #1 thru #8 only. (All 99 messages can be accessed via RS-232.)
6.1 GPI REMOTE CONTROL WIRING (For remote control of Messages #1 thru #8):
There are 2 connectors used for GPI remote control of DigiStor-MP: Connector #1 (P1) and Connector #2 (P2).
P1 is a 12-position euroblock connector used for remote control of Message Play, Stop, and for access to the
primary PLAY RELAY contacts. P2 is a 3-position connector used for remote control of the Record function, and
access to the secondary SYNC RELAY contacts. All Play, Stop, and Record functions are triggered with contact
closures to the "COMMON" (ground) pin, P1-1. Pin-outs are shown in FIGURE 1.
