ON/OFF Functions
I/O signals can be changed between Active High, Active Low, and inactive.
Option
Value
Description
Active
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.
Value
OFF
Set output inactive
ON
Set output active

Pulse-Width Modulation (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
Value
Description
Rate
100 Hz
Signal has a constant 100 Hz frequency with 0-100% Duty Cycle
10 Hz
Signal has a constant 10 Hz frequency with 0-100% Duty Cycle
1 Hz
Signal has a constant 1 Hz frequency with 0-100% Duty Cycle
0.1 Hz
Signal has a constant 0.1 Hz frequency with a 0-100% Duty Cycle
Signal Type Active LOW When the output is inactive, it is in a low impedance state
Active HIGH When the output is active, it is in a high impedance state.
Level
0-100%
Sets the duty cycle from 0-100%

Setting Alarms
Alarms are set by clicking the
icon in SYNC on the desired input signal found in the
Inputs Configuration Tab
.
Setup the threshold and alarm type in the
Condition
section and then select which output to turn on in the
Action
section. The alarm can be set to be latching or non-latching in the
Recovery
section.
