My K8056 board has returned from velleman and seems to work now. When pressing the test button one of the switches is switching on, this looks OK.
When I connect a serial cable to the board and when using the test application nothing happens.
When using a volt-meter I see about 5.1 on the serial line and when pressing a button in the test appication this value drops to different values between 3.0 and 4.4
The data led does not blink and the switches do not react.
Hi Eli,
I have the same problem, the rs232 communication fails. The led stays dark.
I see there are no reactions on your post, my question is: Did you solve the problem in the mean time (if so, maby you could give me a tip). Or anyone else?
The connections seem to be richt.
I am using the demo sw on a windows xp system. With the help of a sniffer i found out that there are signals send over the com-ports.
Should i measure 5,1 over the line in?
How can i make sure the sr323 arrives on the pic? With a voltmeter? I do’t have a scope.
Thanks again
Hans
I solved the problem, i could not measure any voltage on my 25 pins SR232 so i tried the 9 pins and that works allright.
Any suggestions why my 25 pins doesn’t work?
Hi,
thanks for your reaction.
I should be able to measure voltage on pin 2 at the computer but there is no voltage, nothing also on pin 12. (in case of con
The port is enabled in the bios, so I think the computer itself has the problem. Strange enough has my server the same problem, so my two computers fail to work on the 25pins sr232. Coincidence?
