Setting Digital Out Trigger Parameters
Figure 15: GPIO Port Settings Page Digital OUT
Set the trigger type to Digital Out. With this selection, the external device, (for example, an
electric blind) is controlled by the
FC-7P .
When selecting the Digital Out trigger type, the warning popup shown in Figure 16 is
displayed.

The digital output mode function is defined by the pull-up resistor setup:
•
Pullup resistor enabled:
The port is used for controlling external devices such as room or light switches. The
external source device determines the voltage output; the maximum voltage is 30V DC
and the maximum current is 100mA.
Take care that the current in this configuration does not exceed 100mA!
When enabled, the port state is high by default. For the state to be low, you must click Low
from the Current Status.
•
Pullup resistor disabled (default):
The port can be used for controlling devices that accept a TTL signal such as for
powering LEDs. The voltage output is TTL positive logic: open: ~ 3.5V; closed: ~ 0.3V.
When disabled, the port state is low by default and to set it high, you must click High from the
Current Status.
