Output Card does not see output led (SOLVED)

Hi All, I have attached an Opencockpits Master Card, Expansion card, an Input card and an output card to my system. I have attached a switch to the input card and it works perfectly. My problem lies with the output card. I am trying to get the LEDs powered by the landing gear up and down annunciator panel to work. I am running PMDG 737 with OCP4NGX_v4.5.ssi. Everything loads well, when I open SIOC Monitor it gives me IDX=31 - USB Expancion v3 - Device =741. I then double click on this to map my output LEDs. I have connected the LEDs to the output card and when I press "All On" under the Output Commands they all light up. I then go to activate the individual numbered squares to get each LED's address and nothing lights up....... None of the individual squares light up my LEDs. I once again press "All On' and they all light up! Please help me to find out where I am going wrong, I need the individual numbers to place in the script file. Unfortunately I am a newbie so please have patience with me! Many thanks in advance!

Hi,
Take a look at this document on how to wire up your LEDs. Could it be that you do not have the resistors connected to the LEDs?

Thanks for such a quick reply! Yep, I've been through the document, resistors are attached - all LED's do light up under test........

DO you run the SIOC Monitor when OC4BAv4/OCP4NGX is running or is it before you start up OC4BAV4/OCP4NGX?

Only once I've started the sim....... I select OCP4NGX from the FSX menu.....

Just so I do not misunderstand you. The naming of the topic says " Output Card does not....". You mean the Output Connection Card?
I would disconnect the Output card and just wired a (resistor (470 ohm) - LED) to one output on the MASTER Cards J2 connection and tested.

My pc board setup....... Opencockpits all, Master card, Expansion card, input card and output card. I bought the extra IO cards as you can attach wires by simply screwing the connectors and not having to solder........

Problem solved! I found that the common earth wire connector that I was using was not the one assigned to the bank of output connectors that I was using! When I used the correct earth connector all works as it should! A million thanks for such a speedy reply/s and also for always being there to help us when needed! You are a star!
