Sync Setting
① DIO Device [sync_dio.vi]

 

Select when setting synchronous operation on a digital device

 

 

IN/OUT Terminal layout

 

Input terminal

SyncMode

Initial value: 0 (StandAlone)

[Essential]
Select synchronous mode

    0: StandAlone
    1: Master
    2: Slave

- Stand-alone
Specify this when using the device alone or without using it in sync with other devices

- Master
Specify this when performing synchronous operation with the target board as the master

- Slave
Specify this when performing synchronous operation with the target board as a slave

 

ExtSignal1

Initial value: 0

ExtSignal2

Initial value: 0

ExtSignal3

Initial value: 0

When using with master or slave, set synchronization control signal
No need to specify for Stand-alone

- In case of master

Specify the signal to be output to the three terminals (ExtSignals 1 to 3) of the synchronous control connector

About signal assignment to synchronous control connector

Which signal is assigned to each of the three terminals of the synchronous control connector is arbitrary by the user,

but we recommend the following assignment as standard and recommended.

Synchronous Control Signal 1 (ExtSignal1): Clock signal
Synchronous Control Signal 2 (ExtSignal2): Start signal
Synchronous Control Signal 3 (ExtSignal3): Stop signal

 

- In case of slave

Specify whether to use each Synchronous Control Signal (ExtSignal 1 to 3)
