Is it possible to adjust the default time that Vdin buttons when pressed and held remain 'on' for?

We have a multi-master application using a MD4-10 and a MD4-7. On each we have momentary buttons commanding functions that are slow in operation meaning the button has to be pressed for some time- By default the buttons while still pressed go to the 'off' state by Iqan even though still pressed requiring the user to press again- this is not acceptable to the user. We cannot latch the buttons for safety reasons. The buttons seem to switch to 'off' after about 10-12 secs on the MD4-10 but longer (approx 20 secs) on the MD4-7.

I have D-in G, pin #38 hooked up to the brake lights of a truck to detect when the brakes are on.

I recieved a report on one truck that the brake lights don't work when the IQAN system is powered off.

Does the impedance change radically when the system is powered down?

the book states 62 kohm pull-down in parallel with 470 pF. I can't imagine that would draw enough power to keep the brake lights from illuminating.

Is this a faulty module? or is this normal and I need to add a large in-line resistor on all trucks in the field wired this way? Are XS2 modules the same way if this is normal?

eta: when I use a multi-meter on another XA2, I get 62K ohms between pin #15 and pin #38, so I am leaning twoards this being a bad module.

Hi, Appendix A in the manual states there are two VREF supplies for the XC2x range and it delivers 70mA current max. Is that 70mA per VREF (150mA total) or 70mA total across both VREF's?

As you can see the Vref and +Bat are a bit off on MOD4.

any ideas?

What's the current consumption on the DIN and VIN on the XC21/22/23 modules? We are looing at connecting a joystick with some digital switches that can only take a max of 2mA through the circuit, will the module consume more than 2mA on these inputs?

Has anyone had any experience whereby they have used a single IQAN PWM out with a 5A load ?  The data sheets say "no" but I am just wondering if this is possible if the number of outputs used simultaneously, is controlled.

Was wondering what  the temperature threshold is on XA2 units before the internal temp will trigger a warning in the system?

Does anyone have experience to use proportional radio controls via ICP/J1939/CANOPEN. I'm interested about vendors which have radios which i can use in my project. 

I found that Magnetek radios have ICP protocol available but is there any other vendors.

How IQAN XR radio module is used? Can it communicate directly to some handheld radio or with receiver?

I have a MC41 setup where I need to use a bidirectionnal CAM output in PWM mode to drive a bidirectional valve (2 coils). There is a mention to not use a flyback diode in closed loop control but is it ok to add diodes on coils if the outputs are used in PWM mode, not in current output? I tried it and it seems to work just fine.

I want to add diodes as there will be an emergency operation switch installed to directly power the coils. We want the diodes to prevent high voltage spikes to the MC41 module and the switches.

Found on the forum:

With IQAN-MC3 and IQAN-MC43, -MC42 and -MC41, the internal clamping diode is not disconnected when COUT pins are used as open control PWM.

Does that mean that we do not need to add diodes?

I am trying to control a relay with an MD4 output (relay turns on a light when certain conditions are met).

When the IDC channel that controls the DOUT channel goes to false (output turns off) the MD4 is displaying an OPEN LOAD error.

We are running IQAN Design 4.07 on this unit.

Any recommendations?
