 Within the Channel section:

o Set the On parameter to the number of pulses to produce during the on cycle

(‘N’).

o Set the Off parameter to the number of pulses to suppress during the off cycle

(‘M’).

o Enter the required pulse width and delay. Repeat for each output channel.

o Enable the corresponding channels by clicking “Enabled” in the 9200 application.

Pressing the unit’s Run/Stop button will place the unit into active mode and generate a pulse

train based on the duty cycle settings. Pressing the unit’s Run/Stop button again will take the

unit out of the active state (which will not produce pulses). Continue this process for additional

duty cycle pulse trains. See “Output Examples” for a visual representation.

*Note: If a divide-by-’N’ function is desired, the duty cycle mode can be used. The duty cycle

mode is a more general case of this operation. To reproduce the divide-by-’N’ function set

the on cycle to 1 and set the off cycle to ‘N’-1, where ‘N’ is the divide by factor.

External Input Overview

The external Trigger/Gate input may be used to trigger the unit or gate the system/channel

timers. When used in trigger mode, the external input acts as a system start pulse.

Conversely, when used in gate mode, the external input acts in a pulse inhibiting fashion.

It should be noted that when the 9200 is in external trigger mode, a single pulse will be

produced on each active channel for each external input trigger signal when in system Single

Shot mode or system Continuous mode.*

If the unit is in system Burst mode, the unit will produce a single pulse on each active channel

for each external input trigger signal only until the number of specified burst counts is reached,

at which time the unit will become disarmed.*

If the unit is in system Duty Cycle mode, a single pulse will be produced on each active

channel for each external input trigger signal for the set “N” number of on counts but will

ignore the set “M” number of off counts.*

* The 9200 Plus model may be configured to output a single pulse, burst of pulses, or duty cycle response of

pulses upon each external input. See the 9200 Plus External Trigger Modes in Appendix C for more

information. Please contact our sales department for more information about a 9200 Plus.

Generate a Pulse on Every Trigger Input

To generate a single pulse on every trigger input set the following parameters in the 9200

application:

 Within the System section:

o Set the mode to Single Shot mode.

o Set the desired Period.

o Select the Triggered mode.

o Set the trigger threshold level to ~50% of the incoming signal.

o Select which edge (i.e. rising or falling) to trigger on.
