issues with cio dio24h board was created by patburden
I am trying to find some info on how to get my EMC2 software to comunicate through a cio dio 24h board.
As I understand it I have to write or modify a driver for Ubuntu and even then It will not work properly with HAL.
I found an adapter cable online that wil fit the db37 port on my servo board and will connect directly to my db25 parallel port on the back of my computer.
My question is
Has anyone tried one of these Adapter cables? And if so did they have any luck?

Any info or links would be helpful.

THANKS!

Need more info.

Do you have a link to a spec of the board you want to use?
What is it, what does it do?

Is this the board? If so, it looks like an ISA card from the picture.

Thanks for the help.
Here is a link to the DIO CIO 24H Board I am hoping to by pass.

mccdaq.bentech-taiwan.com/mcc/manual/cio-dio24h.pdf

It is connected to the "386 RELAY BOARD" via a DB37 cable
below is a diagram of the "386 Relay Board"
I haven't been able to find anything on this Relay Board online. YET!
I am still looking.

No sir
here is a pictre of the board i hope to by pass.
I hope to connect to the parallel port to my 386 relay board

Not wanting to be the bearer of bad news, but I think you have some pretty significent hardware to be able to omit the interface card. I hope to be wrong and corrected, but here goes.

first issue is this: from the parallel port you can only get 12 outputs when using it without any interface card attached. so you will need to decide which of the other 12 functions on your relay board you are not going to use.

next problem, the signals from the port are only TTL (I think) at best. So you will need to be VERY sure the load needed to drive the stuff on the card you are connecting it to.

third issue: seeing as there is poewr connections in the cable listed in the manual, I am guessing the card you want to use gets power from the interface card you want to bypass. The parallel port has no power connections.

Having said all this, if you can live with the first issue, and the second issue is a non-issue. assuming you can provide the power to the card, this can be very easy from EMC's point of view. Just set it up with a HAL config file to define the output pins as you need them.

I think it probably makes sense to keep the board.

Having read the info here:
www.mccdaq.com/registermaps/RegMapCIO-DIO24-Series.pdf

It seems very likely that minor changes to the driver written in this thread:
www.linuxcnc.org/component/option,com_ku...imit,6/limitstart,0/
will allow HAL to control your existing hardware.

In fact, I have a feeling that that driver will drive your card completely unmodified.

Thanks For the help!!!!
This info Really boosted my confidence that my old mill will live again.
I will give it a try and report back.
I know there are several people out there with these old
ROBOTOOL CVM1 mills with no software, who will be interested.

THANKS AGAIN!!

My question is
Where can I find out "where to and how I should copy this driver"
and also "Where can I find Info on how to "Create" a Hal file

I am completely new to linux and am slowly learning
