How to read multi frame CAN message with NI USB-8473

using USB-8473 to test automotive electrical products: with commands to read serial number from UUT, the expect answer is 28 bytes serial number in format as below:

TX: 03 22 XX XX 00 00 00 00
RX: 10 21 62 XX XX 31 32 33
TX: 30 00 14 00 00 00 00 00
RX: 21 34 35 36 37 38 39 30
RX: 22 31 32 33 34 35 36 37
RX: 23 38 39 30 31 32 33 34
RX: 24 35 36 37 38 00 00 00

 

now the issue is, most of time I only received three frame as show in underline, but cannot received the last frame.

 

my question is the issue relate to CAN card USB-8473 or the LabVIEW code (show in below)?

BTW, all the frame can read with NI PXI CAN card and CANoe device.

 

your help is well appreciated!
