Step by Step Setup for Traxxas Telemetry (Temperature & Voltage)

[MAYOR VXL]

Ok - here is the setup for Telemetry that I got to work for Temperature and Voltage ONLY - I have not installed the Speed/RPM Sensor yet:

Step 1: For Temperature Sensor (heat indicator) - Traxxas Part #6521
Note - you MUST purchase this first because you can not use the Voltage sensor unless you have this Temperature Sensor - the Voltage Sensor actually plugs into this sensor.



Step 2: (Optional but recommended) - Temperature Sensor Mount - Traxxas Part #6535 - this mount is used to tightly secure the Temperature Sensor to your motor. Its optional because if you have a piece of curved plastic and a thin/long wire tie, you can make your own - but for $3.00 - its not even worth the time to make your own. Make sure you dont over tighten the wire tie, you may crush the sensor.



Step 3: For Voltage Sensor (battery indicator) - Traxxas Part #6541 - this sensor will provide you with battery voltage (or combined voltage of multiple batteries). Remember - you must purchase the Temperature Sensor as its required for connecting to your car/truck's receiver to use the Voltage Sensor.



Step 4: Make sure you plug the RED male end of cable of the Temperature Sensor into the RED female end of the Voltage Sensor - then plug the GREY cable end of the Temperature Sensor into the "V/T" slot in your Traxxas Receiver. Basically its RED to RED - GREY to "V/T" PORT in RECEIVER.

Step 5: Download the free Traxxas application from the iTunes store and install on your iPod Touch or iPhone.

Step 6: Connect TQi Docking Station to your TQi Radio - Traxxas Part #6510 (newer TQi models come with this Docking Station) Its required for connecting your iPod Touch or iPhone to your TQi Radio.

Step 7: Install iPod Touch or iPhone into TQi Docking Station on your Radio

Step 8: Turn on iPod Touch or iPhone - do NOT run the Traxxas application.

Step 9: Turn on the TQi Radio - the Traxxas application should automatically launch - if not, launch it.

Step 10: Skip or watch the Traxxas video - once video is skipped or completes, you should notice that in the upper LEFT hand corner of the application screen, the "TX" indicator icon is GREEN. If not close the Traxxas application, turn off the iPod Touch or iPhone, turn off the TQi Radio and repeat steps #7 to #10.

Step 11: Once you have confirmed the "TX" indicator is GREEN - you can now connect your battery (or batteries) and turn on your car/truck. When you do, you should notice that in the upper RIGHT hand corner of the application that the "VEH" indicator is GREEN. If not, turn your car/truck off, then turn it back on until you get the "VEH" indicator to turn GREEN.
NOTE - both indicators will look like this when GREEN:



Step 12: If you now click on the "DASHBOARD" icon - when you do, the Dashboard will start to load, and you then will see the indicators that you have installed. To test the Temperature Sensor rub the rounded end between your fingers to create heat - you should notice the temperature rise. Voltage will increase to the amount of charge you have in the battery (or batteries) connected.



So there you have it - I hope this solves the "mystery" around these Telemetry functions. Ill post an update for Speed / RPM sensor once I have the steps nailed down.

Thanks,

Thanks mate...

Curious as to how its getting the ESC temp?

[MAYOR VXL]

Hughesne - I have it looped around my motor as I am more concerned with the temperature of my motor than my ESC. My motor is always alot hotter to the touch than my ESC - so I figured that is what I wanted to monitor. Also, the Temperature sensor is a loop, and the senor mount is curved, so I am assuming its meant to be attached to the curve of the motor rather than the square shaped ESC...

Thanks,

Great post! I have full telemetry in my ERBE. I connected my RPM wire and mounted my magnet. Took it for a test run today and it seems to be giving me wrong speed. Top speed was 65 after a fast run but didn't seem that fast to me. Need to compare it with another device like a radar because I'm not sure it's accurate .

[josh_1972]

thanks for this update.

How do u connect the voltage to the batteries (2 batteies) ?

[MAYOR VXL]

It only gets connected to ONE of the dual battery cables. The RED and BLACK battery cable gets plugged into the back of the Voltage Sensor cable (3rd picture above) and then the Voltage Sensor cable (with Traxxas connector) get plugged in the ESC power cable. Ignore the BLACK and BLACK battery cable for this setup.

If I remember to, I will try to post a close-up picture of the entire cable setup.

[MAYOR VXL]

Here are the pictures I promised - these pictures show the Voltage connector attached to the RED and BLACK battery cables - as you can see one plugs right into the back of the other:





Let me know if you have any additional questions.

I get that, but your pic shows an ESC temp of 137 and the dial temp (motor) as 96.

[Revoroller]

That is a sample picture from traxxas , not his actual set up. You can rename each item to say whatever you like, and that's why it says ESC, because someone custom labeled it that way. That picture also shows that it's connected to the Traxxas GPS. It is labeled "voltage" and "temperature" as the default.

Great post MAYOR! It answered all of my questions. It would have been nice if Traxxas had provided instructions!

Thanks for the great help... I am very close now... can you post a pic of the how the temp sensor mounts to the motor? I haver the mount, thermal pad, and ty-wrap that cam with the kit, but it's not immediately obvious to me how it gets installed to hold the temp sensor. Thanks again!

[CSTBOY]

Thanks !!!!

Hi, thanks for your post. I have my telemetry working now on my erevo.
My mistake was to connect the battery sensor to the receiver and got always 6V.
I didn't use #6541. I unplug the + connector and solder a red wire on it. Then I connected this wire to the temp sensor by cutting the femelle connector.

[RCx3]

I have the Sensors and The dust cover (part 3792) I also have 6538 magnet holder on the way. Where/how do I install the RPM sensor on the dust cover 3792?

Please help. Pix if possible.

Thanks

[Garfield38]

Here is mount of the hall detector on an e-revo:

[tanman77]

awesome Stuff.. not much info on this...

but u cleared most of the stuff on this new tqi items for me...

still wanna know about the RPM and Speed and wats needed...

R u planning on putting those on?

[MAYOR VXL]

Actually I installed my RPM sensor and after about a week it stopped working. I can tell you that that I installed the LARGER Speed Sensor Magent mount and I heard clicking (rubbing the outer gear case). Since then I have read that we are supposed to use the smaller gear. Taking out the slipper clutch takes a little time - go slow. Just loosen the motor mount, slide it over and the slipper clutch should slide out.

[tanman77]

would did u need to buy to make the RPM to work?

[MAYOR VXL]

Well the smaller Speed Sensor Mount came with the larger one (both in the same package) so there is nothing additional to buy except another magent - which is about $2 at any online hobby shop.

I plan to install the smaller mount once my Spur gear gives out (since last weekend it got slightly sanded down)... Once I do, Ill report back if my Speed Sensor is working again.

[MAYOR VXL]

**BUMP** Too many people keep asking for this post - any chance it could be made a sticky?

[sideshow]

i found this post ages ago and lost it till today
i got my tqi transmitter and sensor wires the other day
fitted the temp and batt wire and i have the rpm wires to go
i found i had to order the magnet and the slipper that holds the magnet
hope to get them in 2 weeks
i think the kilometers are calculated in the app by setting the tooth count on the gears and what tyres
hope to have it all working soon and compare speed with gps
ill get pics up here tonight

[MAYOR VXL]

UPDATE: RPM Speed Sensor

Almost a month ago, I installed the RPM Sensor, and (LARGE) Magnet Mount. Well, it has clicked and worked sporadically since day one. Today, since my Spur Gear finally gave out (teeth were shaved along the top but still usable) I decided to install the (SMALL) Magnet Mount. Well what da ya know - my RPM Sensor now works and works perfectly accurate.

So, let me confirm and finally end the arguement as to which mount to use:

Use the SMALL Mount with the LONGER screws for a perfect fit - that wont click as it spins and provides accurate speeds on the Traxxas Dashboard (on the iPod).

[danielhr77]

Is your magnet mount rubbing against the gear cover? Mine is and I used the small one...

[sideshow]

Yes like mayor said
I pulled my motor and gear off and found cover was rubbing
I also found54t gear had two worn teeth maybe debree got in from it rubbing

Imstill trying to decide whether to send my faulty tqi to traxxas or might be cheaper
To just buy a new one as freight prices in my country hurt in the butt

[sideshow]

Well I went back to my old tq tx and tq Rex and still get poor
I just ordered a new tqi Rx on eBay as they are not to expensive
But until that arrives I'll try the tqi Rx I have here with the old tq tx
To see if I get better results
I've tried another set of batteries but will go buy 10 new batteries this weekend and try that too

If anyone in Australia wants cheap tqi then pm me hehehe

[watchmefly38]

i cannot find where the big black plug on the volt sensor goes help please.

[MITCH316]

Are you talking about the connector in post #12??

[TQi]

nice walkthrough thanks

[Hans_Revo]

Guys is there an adapter needed to connect the volt meter wire to the battery for the nitro versions? I have a nitro rustler.. I noticed
for the electric models you need the adapter part 6541..
Thanks

[Qtop]

I wonder if it is possible to get the actual esc temp without using the motor temp sensor for it.
