View Full Version : Weird Problems SB 595

03-03-2008, 12:54 PM
I have a Sean Bowf 595. All but 16 leds are soldered on.... shouldnt effect anything. I have +5v dc going into it. Triple checked the wiring and DB25 cable. Checked solder joints. I am in EPP mode.

The problem is, it will not work at all. The only time it works is some times when i restart the pc, 4 leds come on. Ive tried everything! wat do i do!

Ill bet that its in the pinout of the parellel to rj45 I wired mine 5 times before I found what I was doing wrong the pin out is the same on all 595s Brians too.
I had all the pins reversed. Dont laugh!!!
If its not that make sure you have ground and the cat 5 is strait through not a crossover. also there is a trouble shooting for the 595 in the wiki

me and brian figured out the main problem : DO NOT LAUGH LOL! i had connected the power to the shunt (jumper) not through rj45. Now i need to know how to connect the power through the rj 45
