Twice Allan, I wrote you an essay on wiring a switch, a Twice I hit the Terms and Conditions button below, which is laid as a trap for my fat fingers, and my comments lost.

Briefly then for you to check that your DPDT is in fact operating as an On/Off switch

Convention is we put the supply Red and Black to the centre poles

The switch then engages the power to the two outer poles corresponding to the direction of the switch push

Thank you Denis for your efforts,much appreciated.

Mike B has put me on a different track by pointing out that the software er9x will run TWO RF modules without any mechanical switching; it's all done in the Menu selections of the software!

Followed the diagram link but ended up with the same result, doh! I must now sit down with the Tx and the manual for a few hours, days, weeks............

One way of powering on the radio is by plugging a trainer jack plug in. This works independent of the power switch.

Connect your battery, then go to the "Trainer" menu. If in trainer mode, it will just display "SLAVE". This will test to see if the trainer jack socket is the cause of your problem. You won't get the "SLAVE" display, if the trainer source is not set to "JACK PPM" at the top right of the display.

Trainer is displayed on the trainer screen, not Slave. I don't even have a Protocol choice on Radio setup to choose a module.

I sometimes wonder if we are talking about the same radio! eg "trainer source is not set to JACK PPM at the top right of the display" Where is that?

Perhaps I shall just file the radio in "failed projects" and get on with building and flying planes with my old SANWA RDS8000!!

Thanks again,

Allan

Well, the 9Xtreme upgrade board from Smartieparts runs ersky9x firmware. I guess you haven't updated the firmware since you got the board. As long as the firmware does everything you need, then you don't need to update it. The current release version of ersky9x is R221. I think the 9Xtreme shipped with R218.

The trainer source is set on the trainer display, at the right of the top line. I'm not sure when I added that, along with "trainer profiles"!

If you are OK probing with a multi-meter (voltage and resistance) I can take you through some places where you may investigate further.

The 9Xtreme schematic is published here: **LINK**.

Correct Mike! An early issue with the micro usb socket breaking off the little board put me off plugging anything in again, though Steven did send a new one promptly.

My board just had small gold pads with a hole in for connecting the internal RF module; should there have been physical pins? As far as I can tell visually it's connected OK. Sure there's a multimeter way of confirming that.....

On that subject, (and with the schematic to scare me), I shall persevere with my multimeter under your benevolent guidance!

One question on updating firmware is how many hands do I need to access bootloader mode if the TX is ON as soon as the battery is connected??

The board never had any pins on the expansion grid.

Probably 3 hands needed for bootloader mode! Possibly you could temporarily wire a switch in the battery leads.

First test, with the battery disconnected, unplug J4 (the 6-way connector in the middle at the top of the board. THe pins are numbered from the left 1-6. Using a resistance measurement, measure the resistance between pins 2 and 3. Try the measurement with the leads both ways round as there are 2 MOSFETs in the circuit with opposing (parasitic) diodes. We are checking for one or both being a short circuit, You should get no, or a very high, resistance.

19.6 k ohms one way and 10.5 k ohms the other.

OK, we will check the power switch. Check the continuity between pins 2 and 3 of the connector that plugs in to J4. With the power switch off (down) there should be no connection, with the power switch up, you should get a short circuit.

Switch seems fine, no continuity when OFF, circuit made when ON.

Please try plugging J4 back in, then connect the battery. What battery voltage is reported on the main display (and what battery are you using)?

Then switch the power switch on, then off. In theory, the firmware should detect the power switch going off and try to shut down, displaying "SHUTTING DOWN", even if it doesn't actually power off.

If you can get into the bootloader (trims inwards at power on), then I can build a special test version of the firmware that can display some information that might help locate this problem.

J4 plugged in, connect battery, main screen shows 11.1 v using the Turnigy 3S 2.65ah Lipo Tx battery pack.

Switch ON then OFF, no "shutting down" msg. The faint warbling sound just gets a little louder with switch ON.

Sure there'll be a way to get into bootloader......

Thanks again for your interest and time!

Do you have eepskye installed on your computer? This makes it easy to backup your existing settings and firmware and flash new firmware.

I have a test version of ersky9x ready for you to flash.

Happy Sunday Mike.

Now this is where it gets difficult..... Down loaded eepe and eepskye from er9x website to get the latest version and arrived at the place I reached 3 years ago. Nothing will install or run with a string of error messages "error opening file for writing" That's where I got to before so to answer your question, "no".

Update: borrowed a laptop, eepskye downloaded and installed in Windows.

Rigged up a switch in battery leads. With Tx switch OFF, and trims held to centre, battery switch ON, no bootloader screen.

With Tx switch ON, trims to centre, battery switch ON, we're in bootloader!

Now to connect laptop and read eeprom.

Next is to flash new ersky9x?

Comms between laptop and Tx seems to be working, can see all settings for models etc.

Awaiting further instructions....

I've posted a specific test version of ersky9x (in "ersky9x9XT_rom_AM_test.zip" here: **LINK**

Please install this, then with it running go UP LONG, then RIGHT several times to the "DEBUG" display. On the 4th line from the bottom there are 4 numbers. What are the last 2 numbers with the power switch ON and OFF?

A little more feedback:

After ejecting the Tx SD card from laptop, I used the Tx switch to turn it off, leaving the battery still connected. The screen went blank as if the Tx switch was working. Then I noticed a very faint glow from the backlight of the blank screen! Turning the Tx switch back on didn't produce a splash screen, just the word "9extreme" in small font mid screen. No buttons changed that.

Another point occurred to me: earlier, before rigging up the extra supply switch, when plugging in the battery, the Tx came on immediately with the main screen ie no splash or alert screens.

OK, now by "Install" do you mean "burn" from the top line of images in eepskye?
