Hi, I have built several of the original 8055 card without problems. However I have just built a 8055N-2 and am having trouble with the card identifying.
I get the following results:
PC Card Result
SKt5 Skt6 Skt5 Skt6
X X X X Card 0 Not found
O X O X Card 1 Not found
X O X O Card 2 Not found
O O O O Card2 Not found BUT CARD WORKING NORMALLY.
I have double checked build, checked voltages, checked Osc Ok with a scope, I am very careful with IC’s, handling them just about every day, but i as suspect of the processor IC, is it correctly programmed?
Has any one else come across any problems and if so did you find a solution?
I had the above all neatly laid out but on reviewing it seems that the post has decided to close up all the chart, did its own thing not what I wanted.

There seems to be something wrong with the card address setting on the board.
Please run the program K8055N_Demo.exe in the subfolder \Demo of the K8055N software package. velleman.eu/support/download … 055N&type=
Click the button Search Devices to see the card address.
The results can indicate the cause of the problem.
Try with all the combinations of SK5 and SK6 on the board.
Please disconnect the card when jumper settings are changed (no need to restart the program).
No need to change the SK5, SK6 setting in the Card Address box when using the Search Devices button.
What are the Device (0,1,2,3) results with different jumper settings on the board?
I have tried as suggested and the card seems to be OK.
However it will not respond to the program written for the old syle 8055 board and I can not understand the thinking of making the new style board incombatable with a program written for the old style board in respect of recognising the board id. This must be due to a change in the .dll file. There must surely be a “fix” for this problem or do I have to modify the program to suit the new board and make my stock of old boards useless?

I now have most working with the exception of card connected signal:
Dim CardAddress As Integer 'Test check boxes to detect card
Dim h As Integer
CardAddress = 3
If CheckBox1.Checked Then CardAddress = CardAddress - 1 'Check for Card connected
If CheckBox2.Checked Then CardAddress = CardAddress - 2
h = OpenDevice(CardAddress)
Select Case h
Case 0, 1, 2, 3
Label1.Text = "Card" + Str(h) + " connected"
Case -1
Label1.Text = "Card" + Str(CardAddress) + " not found"
End Select

This not longer says anything, but on plugging an old board in it works fine.
I seems to have about the same problem… Also I have built 2 8055 boards without any issue. Now I just finished the assembly of a 8055N-2 board…but I can’t get connected.
Only power led LD11 light up…nothing else happens…no detection on pc, no detection with Demo program…I tried, as you suggested, using all the other board addresses and the option ‘SEARCH DEVICES’…but all fails…
Posting a reply on sunday evening…that’s one of the reason’s I like Velleman, and especially the support!
Second reason is because you give solid answers…I’m so ashamed, but I have to admit I made an error with these capacitors… Corrected and the board is running fine!
