Using the External Gate to Control the System
The external input configured in System Gate mode may be used to control the output of the
unit. To gate the internal system timer with an external source set the following parameters on
the 9250 application:

Within the System section:
o Set the desired System mode.
o Set the desired Period.
o Chose *Gated mode.
o Choose the proper *Gated polarity (High/ Low).
o Set the threshold level to ~50% of the incoming gate signal.

Within the Channels section:
o Enter the required pulse width and delay. Repeat for each output channel.
o Set the desired Channel Mode.
Using the External Gate to Control the Channel
The external input configured in Channel Gate mode may also be used to control the output of
the unit. To gate the channel timers with an external source set the following parameters on
the 9250 application:

Within the System section:
o Set the desired System mode.
o Set the desired Period.
o Set the threshold level to ~50% of the incoming gate signal.

Within the Channels section:
o Enter the required pulse width and delay. Repeat for each output channel.
o Set the desired channel mode.
o Set the proper **Gate Mode (Active High/Active Low)
* System g ated mode (Pulse Inhibit mode) prevents the channel from being triggered by the channels’
trigger source. When in Pulse Inhibit mode, if a pulse has already started when the gate is active, the
channel pulse will continue normal output; although, the output will not restart on the next trigger pulse
until the gate signal is asserted again.
See “Output Examples” for a visual representation.
**
Channel gated mode (Output Inhibit mode) leaves the base triggering alone and enables/disables
the output directly (i.e. the output will cease immediately upon the disabling of the external gate
signal).
See “Output Examples” for a visual representation.
Pressing the unit’s Run/Stop
will arm the unit. Once the unit is armed, it will begin generating
pulses whenever the external trigger input is in the active state. When the gate is in the active
state, the system timer is reset.
Pressing the unit’s Run/Stop button again
will disarm the unit.
See “Output Examples” for a visual representation.
