Note: You can configure the GPIO Pin 4 in ACEmanager or ALMS to trigger standby
mode, to sink current, or to pull up the voltage. If you are using the I / O line to trigger
standby mode, you cannot configure it to sink current or pull up the voltage. Likewise, if
you are using the I / O line to either sink current or pull up the voltage, you cannot use it to
trigger standby mode.
You can use Pin 4 in conjunction with events reporting to configure the RV50
Series gateway
to send a report when the state of the monitored gateway changes,
for example when a switch is opened or closed. For more information, refer to the
ALEOS Software Configuration User Guide (Events Reporting chapter).
Pulse Counter
You can use the green wire to connect Pin 4 to a pulse counter. The digital pulse
counter is not available in Standby mode.
