I am trying to read back data from a U2353A multichannel DAQ. I am getting an error message on WAVeform:DATA?

 

My SCPI.

 (INVOKE Query with queryString = "MOD?")

 

(INVOKE Command with commandString = "ROUT:SCAN (@102)")

 

(INVOKE Command with commandString = "ROUT:CHAN:RANG 10, (@102)")

 

(INVOKE Command with commandString = "ROUT:CHAN:POL UNIP, (@102)")

 

(INVOKE Command with commandString = "ROUT:CHAN:STYP NRS, (@102)")

 

(INVOKE Command with commandString = "ACQ:SRAT 100000")

 

(INVOKE Command with commandString = "ACQ:POIN 1000")

 

(INVOKE Command with commandString = "DIG")

 

(Wait 1000ms)


(INVOKE Query with queryString = "WAVeform:DATA?")

The problem.

Step Instrument Code Results
"(INVOKE Query with queryString = ""WAVeform:DATA?"")"

 

"COMException:VI_ERROR_TMO: A timeout occurred | CommunicationTimeoutException:SCPI connection attempt timed out"

 

All code works except the last line WAVeform:DATA?

Any thoughts?
