Problem with 4th Mastercard

[iwik]

Jerry,
Don't put more than 5v on the Master card. PC p/s are dirt cheap and have plenty of current available.
If you need further help just ask.

Thanks, I'll try changing to a larger wire first and if that doesn't work I'll go to ver. 1.0c.

Hello Jerry,

Last night I was reading the Open Cockpits Manual for the USB card. I need to retract my earlier post regarding the need for a 5V power supply. Can you check the manual (At the top of one of the later pages - can't remember the page number) but it says that each of the four Master Card requires 5 volt but NOT the USB Card. In fractured English, it says the 5V connection on the USB card is an output for small accessories - not a 5V input. Maybe that is causing the problem?

Try that and see what happens?

Haven't had time the past week to work on this. I powered each of 4 mastercards with a separate 18ga cable from the power supply. Didn't make any difference. I wasn't connecting anything to the 5V input on my Expansion card. I just tried turning on each Digital Output individually in the SIOC Monitor (all 4 cards) and now with all outputs on there is no error message and all the leds I have connected so far (133) are on. Seems to me the problem is with the ALL ON/ALL OFF Commands in the monitor. I tried clicking ALL OFF and I got the same Access Violation error and none of the outputs went off. Funny, it works fine with 3 cards enabled though.

I have exactly the problem with 4 mastercard with the ALL ON/ALL OFF Commands in the monitor.I do not know how to solve it.

Guys,
Does this error still occur if you disconnect the 5volts to the Master cards?.
If it does then I don't think its a P/S problem.
The problem when one has turn ALL Leds on or off there is a Sudden load on the P/S which can lead to spikes
and glitches which affect software.
Please report back the results.

P.S Have you tried to write a small sioc script to turn leads on and then off. Maybe tie it to
a switch. Your problem maybe a Monitor one and this would prove it.

Hi Jerry

New SIOC version (4,6B1) available: Opencockpits
They have added a nice sioc.ini editiing feature+++

Includes a new release of SIOC Monitor (1.41).

Give it a try and it would be nice to get a feedback.
On my small rig I don't see any problems.

Forgot to come back with this post. When I installed the new version of SIOC it solved my problem with the 4th Mastercard. Thanks for everyone's input.
