I have an MD3 running a small program and an XA2 expansion module.   When connecting only power , GND , Can-H, Can-L and ID tag #3 to the expansion module I get a four red LED blink with no Orange/ Yellow.

No connection message on the MD3.    

The ID code in Iqan Deisgn is the same as ID tag. 

I need to know what are the possibilities to connect MC41 controller with PC to flash program into controller and for diagnostics.

The MD4 documentation states to use 1.5K ohm resistor on the +RTC circuit. Is the 1.5K ohm the only type that is usable, or is there a range that will work?

The MC43 documentation states to use a single 40A external fuse to protect the module. Is it sufficient to run two single 20A fuses, one on each +BAT connection?

Hello,

I have an H-Bridge that drives a DC brushed motor on 12V. I need to determine the PWM ratio being supplied to this motor by the H-Bridge. There is no other signal that could get me this information so I am contemplating hooking both sides of this motor to PWM inputs on the XC-23. Before doing such a thing, I looked at the signal using an oscilloscope. Basically, the signal is 0-12V most of the time but dips below 0V when the ON time finishes. The lowest voltage read with the scope is -11V for a short period of time.

There are no Absolute Requirements for negative voltages on inputs in the datasheet of the XC-23. What is the absolute minimum voltage that can be applied to a PWM input of the XC-23 without damaging it ?

Hi there

I am using a mc41 for my application, my application is led control with the cout, but is it possible to do this, so my Leds can be dimmed? 

Thank you

We installed a G3 modem (with SIM Parker installed) on a customer's machine and we activated the Proemion service as in all other cases. All worked well for about a year; suddenly the service was interrupted, and Proemion warned us that there is no "data plan" for the embedded SIM, inviting us to choose a suitable one. It is not clear to us why the modem worked for a year without a specific "data plan" for the SIM and then suddenly it was blocked. Was there any error in the initial modem settings? In the software there configuration of the modem (through IqanRun) maybe we missed something?

Thank you.

Pardon me if this information is already readily available but am having trouble finding it.

If the wiring for an XA2 DOUT is shorted to battery is there an internal protection strategy in the module that will protect the XA2 from being damage?

Hi,

We have installed a speed sensor (PNP, 15000Hz) onto a MC42 frequency input (pin C1:28, PD).

The problem we have is that the raw value only goes up to about 2800Hz then zero's out with no further reading and we need to get a reading up to at least 5500Hz.

I have configured the input settings to: Max HZ -> 15000 and also the Scaled Maxed-> 15000 to mach the sensor's capabilities and then use the raw reading to scale a RPM value.

We tried adjusting the sensor closer to the ring gear, but no improvement.  

So I did a test to see if it might be the sensor that is faulty by connecting the sensor to a different type/brand of controller. It immediately worked and gave the correct reading constantly.

The question is now... What am I doing wrong on the IQAN side? 

ISO a simple Tsc1 interface module that can convert basic analog throttle Inc/Dec input, to Tsc1 messaging output.  Don't really need/want a display if its possible to do with out one.  Please bare with me as i'm not very familiar with whats possible and whats not.  Thanks Josh
