JetCat info screen

This unit can stay mounted in your model, and will show you the most important values and parameters from your turbine in idle, starting and running mode.



Developed by Sandor Kruise (Digitech Electronics BV / Carsten Groen)

Some Highlights:
The JetCat info display which was exclusively developed by us, is designed for JetCat users worldwide using JetCat engines and ECU's.

The Unit measures only 53 x 20 x 17 mm (active display area is 36 x 10 mm) and is very lightweight (only 20 gr excluding cable).

The JetCat info display has a 2 x 16 characters display, with green LED backlight, the display is readable without any problems in strong sunlight also!

The unit connects directly to your JetCat ECU, or thru the JetCat LED I/O board interface, no other connections are needed. The display simply switches on and off together with the ECU.
Configuration is very simple, during this process you can tell the unit if you have a JetCat GPS receiver and/or a JetCat airspeed sensor connected, and you can even change between metric and imperial units!

Once the ECU is switched on, the display will enter "Idle mode", and show a number of changing screens.
When the engine is starting, the display will change to "Starting mode", and show important information for the starting process, and once the engine has started and goes into idle mode, the display will also change mode to "Running mode"
When the engine is stopped, the display will go back to "Idle mode".

Using the JetCat info display, there is no need to connect your large GSU anymore, you only need the GSU if you want to change some parameter etc in the ECU.
For "everyday use", the info display shows you all you need, and in some cases more that the GSU does!

It even helps you to remember the max pump voltage seen, this enables you to monitor if there is a fuel restriction coming up (filters etc). The maximum pump voltage is recorded by the device, and will be remembered between runs of the engine!

Also the minimum battery volatge detected during the last run is recorded, this is then shown one one of the Idle screens once the engine is stopped (not remembered during runs)

Since the unit is produced as we speak, we can still change the software and make changes to the firmware.
We are open to suggestions if you have any idea's, we might have overlooked something to show on the screens etc.

Nice! Any chance of a Fadec version eventually?

digitech

My Feedback: (10)

should be around 50-60 usd
units are on stock.
please EMail Todd at Dreamworks please.

SpiderJets

Very nice product !

Please bring them to the Pampa Jet Meeting this weekend.
3 for me, please.

No plastic case, eventually ? (How about some transparant heat shrink tube ?)

Nice! I'll take a couple when ready.

I like the product, but if it's going to be mounted in the plane, can the cable be shortened?

Just a suggestion, if you could incorporate into it the functions of the LED/IO board that would be brilliant one less bit to find space for.

you dont need the led io board
you can read from the info screen what is happening

digitech

My Feedback: (10)

we made one years ago , but there was little or no interest for it..
we sold a bunch to martin lambert for the kolibri,s

digitech

My Feedback: (10)

we provide 2 shrink tubes for it included in the package
we left it off in case someone wants to implement it into the airframe or cockpit.

digitech

My Feedback: (10)

yes you can , we provide 1 meter of cable since i think most of the users will use them in large airframes.
but there is no need to shorten it , there is no distortion comming for this cable

digitech

My Feedback: (10)

they are ready and on stock

So can Istill get one from somewhere? Ibet the interest would be higher now - a lot more fadec turbines in the US now than even a few years ago

digitech

My Feedback: (10)

dont think so sorry..

My Feedback: (10)

we got a box full of JC info screens going to the states this week.
i think Todd will be updating his webpage soon with this item.
we are almost sold out on the first batch that came.
so we will be getting more in 10 days or so.

Nice product.  A future "nice to have" feature would be a way to download the data of each run onto a field lap top for record keeping purposes.

I received my first displays from Digitech during the Pampa weekend.
Quality is impressive.
The cable is easy to shorten and re-solder to the unit, the solder tabs are large enough for a hobbyist like myself.
The display seems to be perfect for a clean installation in the plane's main board ; here I installed this one in my BVM BobCat.
Note that I did use the JetCat I/O board for the display connection, but Sandor told me it is easy to install a telephone Y-splitter block (between the ECU and the JetCat I/O board) and hence leave all the wires under the main board.

Congrats to Sandor and Carsten, really a very nice product and highly recommended !

Can you add Distance flown to the output for the Air Speed sensor and Last Run time to the output? I record Max Airspeed, Avg Airspeed, Distance Flown and Run time from the GSU

Sandor,
DreamworksRC is the USA rep for these?

Dave

My Feedback: (24)

Correct...

digitech

My Feedback: (10)

i believe it does all that as long you have the sensors mounted.
you need to setup the in fo unit only once to enable these funtions

digitech

My Feedback: (10)

yes he is the sole importer for these units.
he will also be able to update these units in case of a firmware change in the future.

Unit rec'd from DreamWorksRC today (Wednesday Aug 4th). Downloaded the instructions as none were included in the plastic bag. Works as advertised. Good Job Sandor.

BTW.... software version was 1.1
