[quote]P.S. is there a card planned with more output channels[/quote]At this time, there are no plans for such a device.
[DllImport(“k8055d.dll”, EntryPoint = “ReadAllAnalog”)]
public static extern void ReadAllAnalog_K8055(ref int Data1, ref int Data2);
int l = 0; int lFl = 0;
ReadAllAnalog_K8055(ref l,ref lFl);
progressBar9.Value = l;
//int k3=ReadAnalogChannel_K8055(2);
progressBar10.Value = lFl;
wrote this source code but don`t get Data from the Card
if we use the original Software from Company the Card Shows Data
do you have suggestions
greeting
Found the mistake both Cards work properly now
Thak greetings nice day
OK, thank you for the reply.
I tested your code too…
Indeed, this seems to work fine:
private void button11_Click(object sender, EventArgs e)
{
int l = 0; int lFl = 0;
ReadAllAnalog_K8055(ref l, ref lFl);
progressBar9.Value = l;
progressBar10.Value = lFl;
}
have another Thing
the data when for one day data is kept from the Card is sometimes missing for more the 5 hours
advice would be nice
Thank
greetings
bye
It is very difficult to say what causes this problem.
One possible cause may be some electrical noise interference from the surrounding equipment.
Also thought that this may cause the Problem
because Software can`t cause such a randomize effect
is it possibel to get a filter before the Inputs
where can we buy one
do you have any suggestions
thank
I’m sorry, there no such filter available.
You may try adding 100nF ceramic capacitors between each input terminal and GND.
Is it possibel to get non SMD ceramic Capacitors
or are there also wired ceramic Capacitors
Thank nice day
greetings
possibel that the wires are to long
[quote]Is it possibel to get non SMD ceramic Capacitors

could need some development samples 100nF free of charge to my adress 10 pieces
could the driver dll the cause that data somtimes are not registred by the machine ?
separated data wires from other wires but data still somtimes are not registred by the machine
greetings nice day
[quote]separated data wires from other wires but data still somtimes are not registred by the machine[/quote]Strange, maybe the cause of the problem is electromagnetic interference generated by an external source.
used the card without wires up to now no problems
greetings
did card has been tested with wires
ce conformity test card tested with wires ?
Greetings
I think the card is tested “as is”.
The length of the wires should not be a problem but the electromagnetic disturbance generated by an external source that affects an circuit by electromagnetic induction, electrostatic coupling, or conduction.
Please use shielded cables and connect the shield to the GND terminal of the board.
In very “noisy” environment, put the card in a metal housing and connect the housing to the GND too.
Can the shield of the cable connected to GND
both ends of the cable shielding ?
greetings
[quote]Can the shield of the cable connected to GND
both ends of the cable shielding ?[/quote]Yes, connect the other end of the cable shield to the ground of the external device.
Thank for advice up to now card works perfect
greetings
have a question
the time distance between the second or third data is somtimes more than the double have 10 seconds time between two points but get 21 seconds as example causes the card or the computer this time delay when communication is established? advice would help us
greetings nice day
Think solved problem the machine was too slow memory was not enough ings
Greet nice day sincerly
