811 plugged in ISO interface

[nofear]

Milli or mods-----:confused:
Just received 811 from milli. The ISO interface was not plugged to the 811 main board header per the instructions when I received the unit. The ISO interface was just laying inside the unit
I have no idea which way to connect to header because the ISO interface plug will connect in either direction.
Can someone give guidance on this.
I can ring it out with a meter if told what pins on ISO should be connected to what component /pins on the main board.

Sure would like to get this unit up and running. TIA

Nofear,
I'm not a Mili or a Mod but I can help you on this. Look at the 1st picture in the ISO programming instructions for this unit. Notice that there are arrows. The connector from the card interface is on the opposite side of that chip you see. Also when you are looking at the direction of the ISO interface arrow, leave out the pin to the right. I hope I explained it right but this is how I saw it.

Thanks for your quick reply. My connector does not match the ribbon connector as shown on the instructions. My connector is a multicolor type with the number of pins on the connector and header equal to one another.
Picture shown must be from an 311 because the 811 header sits between the card slot and another very large chip. None of the components shown in that picture match my unit.

Yes, I have the same one 811. When you are looking at the the header from the side where the card slot is, take the ISO programmer cable and lay out the cable with the interface card facing down. Meaning the connections on the interface card facing down. It should say "insert this side down" on the card.

That's the way mine went in. I have 5 pins on my inerface connector and 6 pins on the header. I left out the one on the right because I could tell it wasn't connected to anything. I hope this helps.

Dont want to take a risk with my investment and again I want to thank you for your replys. Didn't quite understand what you were saying but would like to ask a few questions and I think that might clear things up.

You say you have an 811 with the multicolored cable attached to the ISO card so hopefully the cable connectors are the same and we can discuss the connection by using the cable colors. BTW on mine there are 5 pins on header male (PC board) and 5 sockets on header female thats attached to ISO.

A picture would be best but since we dont have one, here goes.
Should the red or the orange color wire on the outside of the cable be connected to the header pin nearest the front of the IRD (811)?

Your answer would be usefull only if the ribbon cables orientation to the ISO connector matches. With the ISO card face down,( ISO pad connectors and "this side down, facing down") and the assemblie positioned with the header connector on the left and the ISO card face down on the right, the red wire is the farthest away. The orange wire is on the same side as the "this side down' writing on the ISO.

Hope this isn't too confusing but I just have to be positively sure.

I forgot to mention that my cable is not multi colored. It appears that we may have a diffrent interface card as well. Let's try and go by the printed circuit board layout of the interface card.

Look at the picture above of the interface card that's for sale. That's the way mine is layed out. The connections on the circuit board facing you (up) and the writing (insert this side down) on the right.

Now turn the card over (card connections facing down) and stretch out the cable and the interface connector should wind up just like the picture that I stated earlier in the how to page of the 811.

In short, Looking at the printed circuit board of the interface card layout (above), the shortest length (to the left) will wind up going to the first pin of the header nearest the front of the unit. This is if they were all modified the same way. I can't see how it's not.

On 311/811 instructions first picture it shows red conductor of grey ribbon connector at ISO card. It is not apparent from picture which end of the ribbon cable has the red conductor at the PCboard header.

If you could please tell me if the red connector on ribbon cable is on the header pin nearest the front of the IRD or the pin toward the rear of the IRD.

I think this would nail down what I need to do to connect my ISO assembly.:D

Tommyoz and everyone else

Found by ringing out header, ISO board and IRD that the red conductor of the multicolored ribbon cable is attached to the GROUND pin of the ISO board.

The pin nearest the front of the 811 IRD is also ground. When you match the red connector of female header to the male header pin nearest the front of IRd the ISO assemble will be positioned to the rear of the IRD and the multicolor cable will be crossing the card slot.

Hopes this helps someone else and a special thanks to Tommyoz for assisting me and spurring me to dig a little deeper to resolve my issue.:D
