= FIRMWARE UPDATES =
== Jeti RMK2 V1.22 ==
''The update of the reiceiver to version V1.22 will give you now an errorfree receiving of the 12 channels. <<BR>> 
It came up with a sporadic and short receiving problem before but it didn't caused a crash because it was to short. Typical was a short "shake" of the camera-servos. <<BR>><<BR>> ''

'' {i} Hint: During the transfer of max. 8 channels this problem didn't appear.  ''<<BR>>

= Jeti-Receiver Update =
== Check on the SW-Version of the Jeti-Receiver ==
You can do it also from the Jeti-Box at the transmitter:

 * Switch ON MikroKopter and transmitter (Jeti-Receiver must be connected before)
 * JetiBox one time right to "<- RX ->"
 * JetiBox one time down to change to the menus of the RMK2
 * JetiBox three times right. Now you see the Firmware version ("FW ver. x.xx")

== with connection to FC2.1 ==
{i} '''Therefore the MK-USB must be connected to the FlightCtrl !'''

Since [[http://www.mikrokopter.de/ucwiki/Firmware-0.82|Version 0.82]] the FlightCtrl can be updated with a Jeti-Receiver connected to a FC2.1 .

{{http://gallery.mikrokopter.de/main.php?g2_view=core.DownloadItem&g2_itemId=70260&g2_serialNumber=1}}

/!\  You can't update the RMK1 with this tool - it's not really necessary!

 * Therefore click with the right mouse-button into the grey area next to the Update-Button and choose "activate Jeti update mode" 
 * Attention: As a type of receiver "Jeti" must be choosen before in the Kopter-Tool
 * The Kopter-Tool will open a data-channel to the Jeti-Receiver and will be closed
 * Afterwards you can use the program "Jeti_RMK2_Updater_x_yyy.exe" to update the receiver
{{http://gallery.mikrokopter.de/main.php?g2_view=core.DownloadItem&g2_itemId=70271&g2_serialNumber=1}}

 * Attention: The MK-USB must be direct connected to the FC ( it doesn't go through the NC )
 * May be the receiver must be connected again
 * After the update the RMK2 must be connected new to the transmitter.

== with Flight-Control <2.1 ==
If you use a smaller version rather than V2.1 it could be possible that the FC causes a "Reset" after you reconnect the RMK2. It's the matter of fact that's not enough capacity on the +V-site.

It'll help you, if you leave the 6-pole-cable connected between FC and NaviControl. The FC uses the capacity of the NC and do not cause a "Reset" after reconnected.

== Connection to MK-USB ==
You can also do an update with this small circuit, if you do not have the Jeti-data cable to the FC:

You can directly use the program "Jeti_RMK2_Updater_1_22.exe" without a start-up of the Kopter-Tool before.

= more hints =
 * With the Update-Tool you can't setup the COM-Port manually. The tool finds the FT232RL-Chip of the MKUSB by itself.
 * You have to use for the Jeti-Update a MKUSB ( or one with the FT232RL-Chip), a different serial adapter is not working.
 * You should only use one MKUSB-Adapter connected to the PC, otherwise a different one will be activated.
 * During the update the little LED must be flashing ! 

More information to the Jeti-Recweiver RMK2 and the setup for the Fail Save you can get under: [[http://www.mikrokopter.de/ucwiki/en/JetiReceiver|Jeti receiver]]
