RE: Ultimate Ediabas/ISTA+ voltage control V2
It is not the presentation of a voltage which is the problem, it is the firmware routine to measure the voltage

RE: Ultimate Ediabas/ISTA+ voltage control V2
This is not for measuring. It can only tell yes/no. K+DCAN cables can't measure voltage (well, theoretically they could measure, but there is no protocol to tell a measured value to a computer using standart OBD cable driver). Even for measuring transistor connected as that I think would introduce big non-linearity with quite wide spread over transistor parameters. Why would someone do that in his right mind, I have no idea, I mean we don't need to measure milivolts here.

RE: Ultimate Ediabas/ISTA+ voltage control V2
My presentation was to show how the INPA (Ediabas sees the tension of the KL15 and Kl30)
Construction of interface K-dcan which measures the voltage on the real KL15 and Kl30 not make sense, surely be cheaper to buy ICOM, For k-dcan KL15 is only the state that the voltage ON or OFF ISTA it should have options for VCI Ediabas KL15 ON or OFF or, as here, a colleague did shows the tension that wynka deceive the terminal, but actually it is only KL15 ON or OFF even though it shows some tension, I wonder if omitec has functions to reading voltage directly works with ISTA http://cartechnology.co.uk/showthread.php?tid=19713 to give interest. I myself only has integrated interface K-dcan voltmeter with display to see the voltage on pins Kl30 (4.5> 16) after replacing the housing k-can If my post helped you hit the thanks and reputation button!

RE: Ultimate Ediabas/ISTA+ voltage control V2
K+DCAN interface which could read actual voltage would not be any more expensive as it is. If it has any MCU inside, most of them have internal ADC. And external components required are two resistors for minimum design. Premium design would include one more capacitor and, depending on MCU input properties, maybe a protection diode would be needed.
Now, if interface could read actual voltage it's not difficult to pass that to ISTA+ with some additional code. However ISTA+ itself does not even try to read voltage via Ediabas functionality so it will not work with omitec or any other thing without outside help. Only ICOM is supported for that natively in ISTA+ and it uses another asynchronous IP communication channel for that (SDP protocol, I guess the same that IToolRadar uses to display info about ICOM state in the bottom window), different from the data channel. What my updated dll does is it multiplexes requests from ISTA and my own voltage control code into single Ediabas' command sequence going into cable driver. |

RE: Ultimate Ediabas/ISTA+ voltage control V2
I have a schematic PCB terminals without DCAN
you can suggest additional elements pcb to monitor voltage KL15 |
