RS20i Installation and Operating Guide Page 120
RS20i Installation & Operating Guide Document # 9301H52900 Ver. 1.01
The screen displays a series of automation buttons, one for each automation output signal (GPO), and a
circle above it that represents the signal input (GPI) state (GPO19 and 20 are outputs only and do not
have an input indicator circle). The input indicator is white when the signal is high or just unconnected.
The input indicator turns green when there is a low signal applied to the pin.
To verify that the RS20i is properly receiving an input from an external source you would
need to make the external device send a low signal on that pin. Then confirm that the signal
is received by the RS20i by checking if the corresponding circle turns
green.
Example: The button at right illustrates when receiving an input signal on
GPIO1.
To test an output signal, press the automation button. It creates a low pulse on the
corresponding output pin. The button turns green in conjunction with the output signal being
low.
Example: The button at right when GPIO1 has been selected. Note that the
circle will also turn green after pressing the button, indicating that it is reading
the low signal on the same pin.
