Table 7.1 – Remote I/O pinout
The particular unit state is verified if there is a short-circuit between the relative Tele Signal pin and
the Common pin (pin 20).
To send a command to the unit (only in remote state) is necessary a short-circuit between the
particular Tele Command pin and GND for at least 100ms.
