The digital audio toolbox b40 can be remote-controlled by means of parallel
GPI contacts.

Shield GND
Electrical specification:
GPI input
potential free by opto-coupler in line with
a current source
ON: +3.5…+30V between GPIx input
and GPx common
OFF: less then 1.5V between GPIx input
and GPIx common
For serial numbers S/N 182 and higher (HW Revision 2 and higher) the
polarity of the GPI inputs has been changed. to make use of the internal
ground based auxiliary 5 V for "low active" switching.
ON: -3.5…-30V between GPIx input
and GPx common
OFF : less then 1.5V betwee GPIx input
and GPIx common
Signal duration must be at least 50msec.
Note : An internal auxiliary voltage feed of +5V is available on pin 9
via a 110
Ω resistor. Ground is available from the shield of the connector
only! When using the auxiliary voltage feed, there is no electrical isolation
given anymore and the risk to inject unwanted noise is high!
Important Note : You must take care about the polarity of the external
voltage applied to the GPIs. Wrong polarity may destroy electronic
components and may cause fire inside the d07!
