X10+ Channel Expander

This thread is for discussing the X10+ Channel Expander.

What is the X10+ Channel Expander? Well, it's a small device that acts as a power expander, channel expander, voltage monitor, and failsafe system for different types of receivers that output a serial data stream. So, XPS Nano (requires firmware upgrade), Nano II, Nano III & RFU, DSM2 and DSMX Spektrum satellite receivers, Futaba SBUS and SBUS2, JR DMSS Mode A and Mode B, Graupner HoTT SUMD and JETI UDI protocols are all supported. The connection between the X10+ and receiver is made using a single cable connection. We offer several lengths of our UltraTwist cables which offer the easiest routing and highest immunity to RFI/EMI. We successfully tested over 60 feet of cable between the X10+ and a receiver, and for fun we tested a 1000' spool of telephone cable and that worked perfectly!

The X10+ is called "+" because it can output up to 10 channels, and with the auxiliary port set to an output an 11th channel is available. The auxiliary port is capable of being either the 11th servo output or accepting 2nd receiver.

The X10+ has a heavy duty (up to 10awg) power input allowing you to power the servo bus properly! As part of our testing, we made the servo bus into a 'fuse' between power connections and pulled [email protected] with no failure of the servo bus. So, it is more than sufficient for powering servos! You can power the X10+ using the normal servo ports, like a traditional receiver too. Keep in the mind that the power going into the X10+ is the power also coming out of it. So, if you plan to power your setup using a 2S Lipo, MAKE SURE that your receiver and servos can handle a 2S Lipo setup! There is NO voltage regulator for the receiver (with exception of the special Spektrum jumper mod to provide 3.3v to the satellite receiver, more on that below).

The X10+ has our popular TattleTale built-in (a $19.95 value!) The lowest voltage captured is shown as a color, and uses the exact same color/voltage as the Tattletale. So, if your LED turns yellow it means the input voltage dropped below 4.5v for at least one frame period in time (11ms-22ms, depending on the radio system connected). This device does NOT lie... so don't ignore a color change - you most definitely have a problem when the LED is not solid green!

Our normal reboot warning is available when using a RFU, Nano, or Nano II receiver. So, if the LED is flashing slowly, it means that the receiver lost complete power and rebooted. It's not possible to have the warning with other protocols as they don't pass this information in the serial data stream.

The X10+ has a serial interface for our new Serial Link. The Serial Link is a USB device that plugs into any USB port on a Windows PC. Windows 95 through 8.1 is supported. Our normal XDP software package has been upgraded to be fully compatible with the Serial Link. So, using the XDP.exe program, you can upgrade firmware, and change any settings - such as channel mapping, failsafe mapping, failsafe time, reverse servos, change offsets (matching), etc. Customers with our XDP wireless hardware are already familiar with how this works. Most of these functions can also be programmed by using just the push button and LED.

The X10+ servo outputs are nearly simultaneous (71us max between channels). This means that customers using non-XPS receivers will for the first time ever have servo outputs that occur at virtually the exact same time. This make a huge difference in swash plate manipulations, split elevators, etc.

Just like all XPS receivers, every channel output can be mapped to any receiver channel. So, you can swap outputs to make installations more convenient. ie, using the two outer servo channels for left and right aileron connections. You can also do things like have three rudder channels and even reverse outputs and set the offset between them, all using the Serial Link.

The X10+ has a failsafe override (on by default). This means that it will ignore the failsafe of the receiver and use it's own failsafe settings. If you don't have failsafe override enabled, then the receiver will provide the failsafe control (which is of little use when only the throttle channel can have its failsafe set). With the failsafe override enabled, like every XPS receiver, you can independently set the failsafe for every single channel. There are three different failsafe types you can choose from: hold last position, user defined position, or signal off (handy for auto pilots that use a loss of servo pulse to trigger a return to home function). Every channel can have a different preset position, and it is done with our live active failsafe. This is accomplished by pressing the button on the X10+ for 2 seconds, at which point you now have 7 seconds to move the controls to where you want them to be during a failsafe condition. Once the failsafe positions are 'locked' into memory, any channel that has had its failsafe type defined as 'user defined' will now go to that position when a failsafe occurs! This is nothing new for XtremeLink customers, but for the first time customers using other brands can see what they have been missing!

Spektrum satellite receivers can be powered directly by the X10+ when using a special solder bridge jumper. This provides 3.3v to the receiver (instead of the normal servo voltage). This means you don't need the adapter cable commonly used with Spektrum satellite receivers to convert 5v to 3.3v. A second satellite receiver in the AUX port would require a power adapter (which we sell).

These boards are heavily conformal coated to make them water resistant.

Keep in mind that you can use as many X10+ boards as you like in the SAME system! You just use Y-cable(s) to connect the serial data connection from the receiver to each X10+ setup.

I'm still a little confused about this product.
I have a Futaba 9C .
What could this product do for me?
Since I fly out here in the sticks of Missouri I'm really behind in all the lastest and greatest rc updates

If there are any other protocols or features that anyone would like to recommend, please speak up! We have used only 1/3rd of the total code space available in the CPU (PPM and redundant receiver support included). So, we have tons of room to add any new features. In fact, the CPU has probably twice the code space that we will ever need - but you never know!

What RF system do you use with your 9C? Is it on 72MHz, XtremeLink or Fasst/S-FHSS? If it is on our system, you can use the X10+ with our Nano receivers or RFU (once released) to use all of the channels your transmitter has available. If you are using a Fasst/S-FHSS you can use any Futaba receiver with the SBUS output and connect it to the X10+ to get all of channels that way (plus the failsafe, channel mapping, and other features not found with any other system).

I'm still on 72, but I am looking to upgrade. Just not sure if I want FASST, Frsky, or something else.

Nano Upgrades

Hi Jim,

I must be missing something.
Downloaded updater 28, placed nano into programming mode, checked with XPS.
Tells me that it has a flashable CPU. Ran updater, returns a non flashable CPU.
Do all nanos have to be returned for upgrade to use the X-10?

Is it possible to post the image with more pixels so it can be printed out with notations that can be read with old eyes?!
