Configuring the Digital Output Trigger Type
The digital output mode function is defined by the pull-up resistor setup:
•
When enabled, the external source device determines the voltage output; the maximum
voltage is 30V DC and the maximum current is 100mA.
The port state is high. For the state to be low, set Current Status to
Low
.
Use this setup to control external devices such as room or light switches.
Make sure that the current in this configuration does not exceed 100mA!
•
When disabled, the voltage output is TTL positive logic: open: ~ 3.5V; closed: ~ 0.3V. The
port state is low and to set it to high, you must click
High
in Current Status.
•
Use this setup to control devices that accept a TTL signal such as LED powering.
Set the trigger type to Digital OUT. With this selection, the external device, (for example,
an electric blind) is controlled by the
VS-622DT
.
To configure the digital output trigger type:
1. In the Navigation pane, click
IO Gateway
. The IO Gateway page appears (see
2. Click
GPIO
).
3. Select
GPIO 1
or
GPIO 2
.
4. Set
Trigger Type
to
Digital OUT
. The following warning appears:
