Confirm the setting with “OK” or leave the dialog without adopting the new value by pressing
“ESC”.
7.4.4.6 GPIOs (Power S. Connector)
With this setting, the behavior of the two programmable GPIOs can be defined.
The power supply connector (POWER + IO, s. chapter 8.1) provides the “programmable IN” and the
“programmable OUT” lines, where different signals can be provided.
o
In order to define, which signals are to be allocated to the IOs, select the setting “GPIOs
(Power S. Connector)” (s. Figure 141) and press “OK” or the hotkey “Edit Value”. The following
dialog appears (s. Figure 160. Dialog for setting the GPIOs).

Input (Pin 2)
A signal can be allocated to the “programmable IN” pin (s. chapter 8.1, POWER + IO).
There are two setting possibilities for this pin:
1. PTT: This setting defines “Pin 2” as a source for the PTT signal. The software will look for PTT
signal at this pin as well as at the actual PTT input pin (s. chapter 8.1, POWER + IO). Both
sources are valid as PTT source.
2. No Function: This setting means that the pin will not be related to any function.
o
To configure the programmable input pin, press the hotkey “Edit Value”, while the setting “Input
(Pin 2)” is marked.
