13.3.1 INTERFACE PIN-OUT WITH JUMPERS J12, J13, 14 AND J15 IN ‘OPTO’
CONFIGURATION
Two opto-coupler outputs can be used to start and stop a connected equipment. As a maximum, 24Vdc, or 10mA current
may be switched. The outputs are active continuously (latched) or momentary, depending on the J16 jumper (see par.
13.2).
Note: the Remote Interface provides just one Start and one Stop remote for both A and B inputs. Start / Stop commands
may be routed to the piece of equipment that needs to be controlled remotely via external, customer-designed circuits.
Depending on the selected Input (A or B), a + 6 VDC will appear on Pin 9 (Input A selected) and on Pin 5 (Input B
selected) on the remote interface.
Only one of the two Pin will be therefore active (=high) at any time, depending upon the setting of the B SEL switch
(see).
+ 6 Vdc source (with Input A selected)
Collector of photocoup. - Stop command
Emitter of photocoupler - Stop command
+ 6 Vdc source (with Input B selected)
Collector of photocoup. - Start command
Emitter of photocoupler - Start command
The remote Start and Stop can be made either momentary (pulse) or latched by setting the jumper J 16 (ref. to
previous paragraph). If no jumper is set, the Start / Stop remote operates in momentary mode.
Please, consider than max current allowed on optocouplers is 10 mA (nominal: 5 mA). If needed, apply the provided +
6V tension through a 560 Ohm carbon resistor in order to preserve optocouplers from extra currents.
NOTE A: Nearly all modern devices require pulse start commands. Continuous signals however, can have the advantage
that during broadcast a CD player cannot be accidentally stopped. One disadvantage however is that some CD players
are blocked from other functions when started with a continuous pulse.
NOTE B: Some of the older equipment, require additional relays or switching transistors to operate satisfactorily, contact
your dealer for more information.
