Output Settings
To use a pin as an output, set up the Output Options and assign the output to an Alarm using SYNC.
Output options are set in the Output Tab of Omega Sync. Each output can be configured as either Active High or Active
Low. When configured as Active High the output conducts normally and becomes high impedance when activated. When
configured as Active Low the Open Drain output is high impedance normally and will conduct when activated. It is
recommended to change the input type to match the output type so that the output state will be correctly represented in
logs.

ON / OFF: Controls on/off functions. I/O signals can be changed between Active High, Active Low, and inactive

PWM: Pulse Width Modulation controls the amount of power given to a device by cycling the on/off phases of a
digital signal. PWM consists of a duty cycle and frequency. The Duty Cycle measures the amount of time a signal is
in the ON state as a percentage. The frequency controls how fast the PWM cycle is repeated. Users can select
between the following settings:
Option
Rate
Signal
Type
Level
Value
LOW
When the output is inactive, it is in a high impedance state.
HIGH
When the output is active, it is in a high impedance state.
OFF
Set output inactive.
ON
Set output active.
Value
100 Hz
Signal has constant 100 Hz frequency with 0-100% Duty Cycle.
10 Hz
Signal has constant 10 Hz frequency with 0-100% Duty Cycle.
1 Hz
Signal has constant 1 Hz frequency with 0-100% Duty Cycle.
0.1 Hz
Signal has constant 0.1 Hz frequency with 0-100% Duty Cycle.
Active LOW
When the output is inactive, it is in a high impedance state.
Active HIGH
When the output is active, it is in a high impedance state.
0-100%
Sets the duty cycle from 0-100%.
