Functionalities of GPIO :
8 logical inputs
●All inputs are galvanically insulated
●To trigger an input, it is necessary to create a contact between one of the 8 contact pins and the common point (0V)
●All types of contact are accepted :
- Relay dry contact
- Push button
- Relay output of a sensor (temperature, light, smoke, pression...)
●Reclosingdelay between 2 contacts : 500ms (eliminate contacts bouncing)
Each input is allocated a programnumber on the player accordingto a binary progression (see table below).
Example : If you make contact on input 5, you will trigger programN° 16.
Combinations of inputs are possible in order to use allprograms between 1 and255.
Severalinputs canbe connectedtogether toachieve a binary coding.
If you do not know binary coding,here is a simple methodto findthe correct programnumber :
Using the table opposite, just add up the values in the «N° Prog» column corresponding to
eachinput used.
Example :
1 - If you create a contact on inputs 6 and 8 at the same time, you willtrigger programnumber 160 (128 + 32).
2 - Linking inputs 1, 3, 5 will trigger program21 (1 + 4 +16).
3 -If youcreate contactson allinputssimultaneously,you willtriggerprogramnumber 255(1 +2 +4 +8 +16+ 32+ 64+ 128)
4 outputs on static contacts
●All ouputs are galvanically insulated
●Output on static relays
●4 outputs with a common point
●Breakingpower : 100V (ACor DC) 200mA
●Maximumresidual resistance in commutation : 8 Ohms
●Non commutated leakage current : 1µA
Each relay corresponds to an output number on the player accordingto a
binary progression (see right hand table). A «1» represents an activated
relay, «0» a non-commutated relay.
If you do not knowbinary coding, hereafter isa simplemethodtoselect the
correct output number.
Using the table above, add up the values in the «output N°» column
correspondingto eachof the selected relays.
Example :
- If youwant to activate relay N°4, thenselect output 8
- If youwant to switch all the relays off, select output 00
- If you want to activate relays 1 and 3, programoutput 5

TALK OVER function:
The «Talk Over» function attenuate the main musical source to
deliver the message and recover the previous level after the file
delivery.
Delay and timeare adjustable.
To activate the attenuation, just select «output internal relay 1»
withthe timer message program
Note : when relay 1 is activated, the Talk over
function is also activated
To desactivate the Talk Over, just send a new action to desactivate
«outputrelay1»
To adjust delay and time, turn the potentiometer through the small
hole.
Note : Make the adjustment using the Talk Over function and create
aspecific programfor that.
