First time doing this, and we have about 8 hours to go before we preview this to everybody.

Whenever we turn a channel on in vixen, 8 more next to it light up as well. I.E. turn on 1 and 1-9 light up, turn on 2, 2-10 light up, 3, 3-11 light up...so on and so forth.....parallel port is set to EPP....any ideas?

What is the channel range set at in the plug-in's?

1-64 olson 595 plugin

and you clicked the 'plugin set up' button and defined the channel range there also?

yeppers...all are set to 1-64

OK, well, the usual check list...

check port setting... done
check plug in.... done

check for solder bridges

check the input cable

make sure the power supply ground and parallel cable ground are connected.

don't see any bridges and the cable pin out tests like it should

RJ45 DB25
3 18
5 1
7 14
8 2

Turning on one channel(any one channel) turns on the following 8 channels as well....if it was a bridged solder point, it would only be doing it for one block of lights....but anywhere on the board turns on whatever channel we choose as well as the following 8 channels.
Have tried both EPP 1.7 and EPP 1.9

Really getting down to the wire here, any suggestions?

The only other thing I can think of is a board voltage problem. You might need to adjust the voltage up or most likely down to match your paralell port voltage. This is the number 1 maybe number 2 most common problem with a 595. You will need an adjustable voltage regulator to adjust the supply voltage going to your 595. You can get al of the parts needed to make a regulator at Radio Shack. Assembly is easy. I hope this helps.

is there an option with the EPP mode that has 'enabled'. Make sure that is checked.

what is the voltage supposed to be....with "all on" this is the voltage we're getting on each pin from the cat5 end

1 -0
2-0
3- -.01vdc
5-.07
6 .0
7-.02
8- 4.38vdc

With all Off
1- 0
2-0
3--.01vdc
4-0
5- .07
6-0
7- .02
8- .07

and to power the board from a molex connector we're getting 5.06vdc

Are you sure your pin #'s are correct? Pin 1 should be close to 5v not pin 8.

This is where I got the info on the cable, it was from your reply to this post

I'm saying pin 8 is Brown/white.....and pin#1 on RJ45 isn't used at all correct?

This is the pins on the RJ45's

Component Side (looking down at pcb)
[siteimg:fa5fef1f1c]131[/siteimg:fa5fef1f1c]

and from the solder side (bottom of pcb)
[siteimg:fa5fef1f1c]132[/siteimg:fa5fef1f1c]

Are you saying if I look down at my rj45 head with the tabside on the back, connector side on top, Brown(pin 8 should be on the far left, and White/orange(pin 1) should be on the far right?

Because we have opposite of that right now

How about popping intot the chat room, troubleshoot at realtime.

Tab down looking down the wire... pin 1 is on the left. The images are correct.
