DAPL Output Configuration Commands

Output configuration commands define signal generation with clocked output updates. The output sequences are characterized by the number and sequence of channels, timing, output periods, and hardware triggering.

Output configuration commands are bracketed by special group delimiter command lines.

ODEFINE

Begin a group of commands that define an output updating configuration.

END

End an output updating configuration definition.

Configuration commands appear between the ODEFINE and END lines.

CHANNELS

Declare the number of output channels to be defined in the configuration.

SET

Establish the destination port for an output signal, associating it with a logical data channel.

TIME

Set the time interval between consecutive updating operations.

COUNT

Set the number of updates to send before automatically terminating output updating.

CYCLE

Specify the number of terms for a repeating output waveform.

OUTPUTWAIT

Specify the amount of buffered data to collect before proceeding with hardware-clocked updates.

HTRIGGER

Select a hardware trigger control mode.

CLOCK

Select a hardware sample clocking mode.

UPDATE

Select continuous or burst updating mode.

MASTER or SLAVE

Selecta synchronization option for a multi-board system.

Subject to irregular time delays from task scheduling, some special processing commands can bypass the output clocking and send updates directly to output ports.

DACOUT

Bypass output clocking and send data directly to a digital-to-analog converter port.

DIGITALOUT

Bypass output clocking and send data directly to a digital port.
