Figure 14: Simultaneously Updating the Analog Output Channels of Multiple Modules
In this scheme, you must configure the trigger source for one module (called the master
module) as
Software
. Configure the trigger source for the other DT9850 Series modules
(called slave modules) as an
External Positive TTL
trigger. In this configuration, the
DAC_Sync signal is configured as an output on the master module and as an input on the
slave modules.
To start the operation, issue a single values command on each of the slave modules. Then,
issue a single values command on the master module. In a single values operation, you
specify the output channels to update and the value to write to each analog output channel.
The master module automatically sends a signal from its DAC_Sync pin to the connected
slave modules, allowing the analog output channels of all connected modules to be updated
simultaneously with the values that you specified.
Note:
If you are using continuous output mode, described on
, the DAC_Sync pin
cannot be used to synchronize multiple modules.
On power up and reset, the DAC_Sync pin is an input signal.
