Test purpose: Test the High speed function in handshaking transmission for PCI-1755 FDI&FDO
As to the handshaking transmission, I have done some test such as doing the data transmission from
FDO port to FDI port.
Please see my test procedure as below.
1. After installation of this card, please see the wiring as below.
2. I set the FDI to be 16DI/ 16DO in Advantech devicemanager.
Then open two example “ DI_DMA_BM & DO_DMA_BM”.
Please see the setting as below.
3. Then run FDI example first.
4. After FDO running, we can see the receiving FDI data. (Notice that the speed is 5 Mhz)
(Because we only wire 4 DI channel to 4 DO channel, so we only can see the last number(HEX) change. (fff2)
5. Also we can use the 8255 handshaking mode. Then we don’t need to connect the EXT_Clkin and EXT_Clkout.
(Please see the wiring diagram in step 1)
