Hello,

I have a drill rig (Geoprobe 6712DT) which has an MC3 Module installed. Recently, the hydraulic pump would intermittently would stop building operating pressure, and the only workaround I can find is to bypass the MC3 Module and manually force the pump to build pressure. The Module is giving me a 1:2 error code, or "Input" error. Could someone help elaborate what this error could mean in the general sense? Any info would probably help with my troubleshooting. I'm guessing it could be something as simple as a loose wire, but I can't seem to find any so far.

The drill rig comes with the MC3 Module installed, and has worked fine up until recently. The manufacturer doesn't really provide any troubleshooting in regards to said module, so I'm kind of just winging it. The manual for the module tells me that it is an Input Error, but I'm not really sure what could be causing that.

Thanks in advance for anyone who can help me out. My apologies for being somewhat ignorant as to this thing... I'm just a humble driller.

A 5 year old MDL2 is giving us this exact (system) pop-up message:

"

Log error

Failed writing. The log has been stopped!

"

My guess is that the (flash?) memory is full or corrupted, so system events like a startup or sensor error can't be written anymore. Not a big deal, but:

* How to get rid of the message

* In case the log memory is corrupt, would that also threaten other memories? In other words, should we replace this MDL2?

As far as I can see, this a fixed system message, not a custom pop-up.

I am using an MD4-7 screen on a test bench. 3 out of 4 starts I get either a White Screen or a black screens with some colored dots. Once I saw what seemed to be blocks of black and white.

Looks like the video driver is not starting properly. The application appear to be running since the canbus messages are being generated.

Can this be caused by the regulated switching power supply during start-up or do I have a defective MD4 screen?

Thanks for your inputs.

Is there any plan to introduce Ethernet port to other master modules than MD4? It is quite a good feature in my opinion,

Our company uses an IQAN MDL2 setup which ties into the J1939 network of a Caterpillar system.

Our setup is using the internal resistor on the MDL as the terminating resistor on one end of the network and has a standard 120 Ohm resistor wired into the other end.

A machine in the field is having CAN network issues. Typically I am used to checking the resistance of the CAN network and the resistance of the terminating resistors as a standard checkout of the wiring. However with the internal resistor this is proving difficult.

In our lab I powered up a test MDL2 and checked resistance at the MDL with the MDL powered up but no other wiring attached. I found that I would measure ~69 Ohms across the internal resistor at first power up. If I shorted the CAN Hi and CAN Lo together by touching together my multimeter probes it would cause a CAN C "CRITICAL ERROR". After this error I would measure ~115 Ohms across the resistor until the power was cycled on the MDL.

All this said, my questions are:

-Do you have any recommendations for a standard procedure for troubleshooting CAN wiring/resistance?

-In light of the testing I did in our lab could you provide an explanation on how the internal terminating resistor on these IQANs work?

Thanks

Dear

For railway application, one of my custumer will be interesting to connect the Iqan SV ( camera ) to the display MD4 without wiring. We are looking for “Wireless system”

Do you have a solution ?

Best regards

Our customer would like to be able to see "envelope lines" on the IQAN camera view....similar to automobile backup cameras. Also, a way to allow a pop up alarm on top of camera view so operator is alerted to look to another page or view for fault.

How long does a static image need to remain displayed on an MD4-7 screen before image burn-in is noticeable?

Assume worst case. (Worst case being probably full brightness with high contrast graphics??)

What is the recommended time-out for when a screensaver should start? Would just dimming it for the screensaver avoid burn-in? How much should it be dimmed?

The MD4 instruction book (rev 2015-12-02) says:

Burn-in

The IQAN-MD4 TFT display, like other computer screens can have a ghost picture

occur if a static image is left on the display for extended periods of time. For the best

viewing over the life of the product we recommend using the screensaver functionality.

NOTICE

Does anyone know a WiFi camera still using MJPEG format?

It looks like all WiFi cameras are using H.264 format now,

The updated version of the IQAN-XC10 with support for DOUT diagnostics has been released.

DOUT-A to DOUT-P

These high-side DOUT:s can be configured to detect open load when the outputs are off. The detection is based on a shared "strobe" function, giving out a limited current at regular intervals. The detection is suited for loads such as solenoids, but should be kept disabled if any of the high-side DOUT:s are driving smaller load, e.g. LED lamps that will blink when this feature is used.

DOUT-Q to DOUT-T

These low-side DOUT:s can be configured to detect open load when the outputs are on. This diagnostic feature is based on undercurrent detection. The detection is suited for solenoid valves, but should be kept disabled if the DOUT is driving smaller loads, e.g. most relay coils.

PWMOUT

The PWMOUT has open load detection based on measuring undercurrent also in previous versions. Now the option to disable undercurrent detection is available.

For more details on the DOUT/PWMOUT diagnostic features, see IQAN-XC10 instruction book, Appendix A.
