The good news is that with the PPJOYCOM driver I managed to get the Transmitter working with FMS last night.......

I have not done exhaustive checks yet but, if it worked for 10 minutes, the rest is just tweaking...

There were several pointers but I put them altogether last night

1) You do not need to turn on the Transmitter or remove the crystal. The power for the RS232 chip is provided via the DTR line
in the 9pin D connector
2) I can confirm that you get input corresponding to all 4 channels (spent a little time trying to work out the FMS names for things versus what the cyclics did --- but, being a novice, this is part of the learning exercise)
3) Using Windows 98 it took me a little while to re-read Deon's comprehensive documentation and install a LPT driver before the Joystick driver and then run PPJOYCOM. The !QUOT!bleeping!QUOT! debug option on PPJOYCOM helped to give a warm feeling that the Transmitter
was communicating
4) Ran up FMS, chose joystick. Saw two joysticks (I already have a 2 channel games joystick attached to the system) and then started allocating channels to functions

I'm sure that the order I did things is not optimum but, as I mention, it worked.

Thanks again to everyone who has helped to resolve this problem

Dave.

My friend got Laser 4 Channel Transmitter and he is using serial cable. It works in WinXP/2k.

This is the thing we found out:
FMS (current beta version) DO NOT WORK ON ATi Radeon graphics card (9x00). U will see that the FMS will eat up a lot of RAM before it terminate itself. I suspect that it is possible due to DirectX 9.

To make it work, U can either use another NON ATi Radeon card on your system. It should work on WinXP or Win2k. If you do not want to change your card, then use another computer or run VMware Workstation (www.vmware.com) and create a virtual system.

Did you mean you used the Zhen Hua 4-CH PCM with FMS successfully? I tried everything with win2k, and still have not be successful yet. I meant using the serial cable that supplied with the TX. Please clarify your steps. Thanks.

Yep, with Deon's PPJOYCOM Virtual Joystick driver I managed to get the Zhen Hua working fine
with FMS and WINDOWS 98. I do not have access to a system at home with W2K......

I used the COM cable supplied with my Zhen Hua (4 wires - RX, TX, GND and DTR) and connected this to my COM2 port (via a Null Modem)

I then installed Deon's PPJOYCOM driver as per his documentation at http://www.geocities.com/deonvdw/PPJoy.htm and ran up the com port driver he made available a few posts ago in this forum.

Select the correct COM Port from the pull-down bar and select the Zhen Hua TX from the second pull-down bar. If you select the test box then beeping will indicate that the Transmitter is sending codes to the PPJOYCOM driver.

Another couple of post (and private emails) also correctly stated that the power for the transmitter would come via the RS232 connector.

In my case I needed to use the null modem to make sure that the Transmitter would communicate. I usually have an external modem connected to COM2 and I need the same null modem to get that to work.

When I ran up FMS, I chose the Joystick as the Control device, calibrated it and everything then worked as I expected it to.

Hope this helps.... Cheers, Dave

Status: offline 		I ordered the Jabo mini-heli and also the FMS sim. I got an email from TTi, Inc. asking about which cable I required. Being new to this I emailed Tom back with photos of both the Jabo and the serial cable. His response was as follows:

"Unfortunately the cable as is will only decode standard PPM signals. The
ZhenHua PCM-4CH sends out a proprietary stream of signals (not
standard). In addition, the connection for the ZhenHua is also non-standard."

Tom is looking for someone to lend him their PCM-4ch tx
so he can build a custom connector and modify the software accordingly.

It would appear then that FMS does NOT natively work with the FMS simulator.

Just my 2 cents...

I have fixed this bug and uploaded a new version of PPJoyCOM to http://www.geocities.com/deonvdw/PPJoyCOM.htm. The new version is "Version 2.1b test" (in the About... dialog)


Just to let you all know - I have released a new version of PPJoy (v0.78) and the package includes the latest version of PPJoyCOM (v2.2) so there is no longer a need to download PPJoyCOM separately. The PPJoy homepage is at http://ppjoy.uni.cc

If you are only using PPJoy for the Zhen Hua support there is no real reason to upgrade to the newer version.

Status: offline 		Hi Mick

I can only say that with Deon's Joy Stick driver and my Zhen Hua (of which there are details earlier in this thread) everything works for me. I spent a good 30mins last night crashing heli's (that's why I needed the Sim).

The "unique serial string" was reverse engineered and Deon's PPJOYCOM interface caters for this "uniqueness".

Please email me if you need details of my RS232 lead. It terminates in a 9pin female D connector. 4 wires are connected which (from memory) correspond to RX, TX, Gnd and DTR but I can buzz them through if you would like.

As I posted last night, I needed a NULL modem on my PC.

The "unique" coding was provided earlier in this thread.....
---> PASTED FROM the "Comments and Suggestions" (on FMS forum)

I would like to add a serial interface mode compatible with the zhen hua helicopter controller. It doesn't seem to work with any of the existing controls. I reverse engineered it and it uses RS232C async serial bytes in 5 byte packets running at 19200 bps. The first byte in the packet is 0xEF, and the remaining bytes are the four controls (one byte per control). The controls are coded by reversing the bits in the byte (msb becomes lsb). Where 0 is the lowest value. How can I add this to the FMS codebase?


Good luck.....

I finally discovered how to use FMS with the Zhen Hua Radio!!!

I only installed the PPJoy software and configured the Virtual Joystick1 using serial port COM1 and selected under serial protocol "Zhen Hua 5 byte Protocol". Note: Do Not Close PPJoy, just minimize it.

Then start FMS and configure the control as follows:

Under Control menu choose Analog Control.

Then select Joystick Interface fron the list.


Now select Mapping/Calibration and use the following for Mode2 Radios:


Calibrate the controls...

And your'e ready to simulate!!!
Enjoy!

I did it, and it worked great with Win98. Thanks for Deon's PPJOYCOM Virtual port. Remember everyone to leave the Deon's PPJOYCOM Virtual port open and turn on FMS. Everything should be okay.

Have anyone tried to interface the Feda Zhen Hua remote with FMS under winXP? Please let me know your trick if you have it worked. I tried and no success. Thanks in advanced.

I bought myself a new Dragonfly 22d. Everything is set up well according to the instructions. Yes, I had to manually install the two drivers with window 98se. I got to the point that the PPJoy serial steam is reading from Zhen Hua 5 byte protocol. However, when I turned on the beep on serial input (debug), there was no sound. When I opened up the analog joystick interface. I could see joystick 1 with several vertical bars at various height. However, changing the channel settings and calibation did not do anything. The program failed to respond to the radiocontrol unit.

Any suggestion is greatly appreciated. By the way, why did you say "do no turn on the transmitter"? Do you mean during program installation? And afterward? Thanks.

I still have not tried to fly the helicopter yet due to bad weather. I heard from others that the motor tends to overheat, They also feel that the build is cheaply made, even though I have nothing else to compare too. I am not surprised for the second point due to its cheap price and the manufacture in China. However, I should have got a heat sink as in the first placel.

Status: offline 		What is it about us Dumb Network Engineers, We don't have enough computer problems at work! I just hope you were not as dumb as I AM, too have purchased your heli from the same dealer. NOT EVERY ONE... #1 If you purchase a Heli on EBay, Read only the negative feedback, left for seller. Most Idiots leave positive feedback, when the received the product, and not after they have tried to use it. #2 DO NOT purchase a product from China, if it cannot be supported or get replacement parts locally or at least within the SAME Country. #3 Try calling China at 10:00pm at night (our time) and find someone who speaks English.

NOTE: DO YOUR HOMEWORK ON THE HELICOPTER YOU ARE LOOKING TO PURCHASE, BUT MORE IMPORTANTLY THE DEALER WHOM IS SELLING IT, IS MORE IMPORTANT.

YOU WILL CRASH IT, NEED PARTS FOR IT, AND YOU WILL NEED SERVICE AND SUPPORT.

Getting Back to the subject: I was told by another as dumber individual that, that he received an e-mail from the dealer saying that the 6 channel Dragonfly transmitter doesn’t work with FMS !!! I don't know if this is true.

Status: offline 		The FMS is a popular and free program. Unfortunately, sinice it is a freeware, it is not designed to accommodate all transmitter. Zhen Hua uses a simple 4-pin connection via the serial port. That is why you have to use the PPJOY program to convert the signals. Most of the time, it will work. Make sure that you have:
1. Batteries in the transmitter. It has to be turned on and powered.
2. Take out the crystals or RF modules, or else nothing will work.
Compatability is not 100% guarantee.

If everything fails, you can try another stimulation program. The official Zhen Hua company website has a link for the software. Unfortunately, it is not in the zip file. The correct English version can be downloaded from:

http://chipcheap.com/Jesse/truflite2.zip

NOTE: You dont need PPJOY for this program. You have to have up your transmitter and connect it to the computer before you start the program. At least, on my computer using Window 98SE, this program is NOT compatible with FMS. (ie. you cannot use one and then the other or vice versa).

Finally, the Zhen Hua transmitter is not a piece of garbage. The common problems with most of the products from China are that they do not last long due to poor quality control. The Zhen Hua and other similar helicopters tend to have its motor overheat easily. Therefore, use a heatsink in warm weather condition. In addition, finding replacement parts will be difficult unless you order oversea.

Hope this will hellp.

For all of us Dummies that have spent hours and hours of time screwing with this, its never going to work...... Unless you get a different transmitter

Status: offline 		Hello all,
I am using the Zhen Hua Tx with PPJOY and FMS. It works ok. BUT, for some reason channel 3 (throttle) never works. Even in Windows Joystick setup, the bars do not indicate any movement on the throttle signal. Hmm.. quite peculiar that the other three channels work just fine. Why not the third channel for throttle? Very unusual!
I have wired my own cables before. I made a 25 pin for the Parallel port and a nine pin for the serial port. I never got the Parallel port method working in WinXP Pro, nor in Win 98SE. However, the serial plug method did work in WinXP, but not in 98SE.
Regarding pinouts of the various Tx's: The Tx sends all channels, one after the other along one wire. It is a simple matter to use an oscilloscope to find the outgoing signal. Just ground the probe to the ground point on the Tx's socket, which is always the outer sleeve. Then probe the other pins one at a time to find the signal. I use a time/division of 1ms and volts/division of 1. Of course the Tx has to be "on" in order to work. I read in some other posts that the Tx can be turned off. Hmm.. that would ONLY be if the power is being supplied by the serial port. If you have just the basic serial cable, then of course there are only two wires in it (for Futaba Skysport 4 and most other Tx's). One for ground and the other for signal. So don't expect it to power your Tx. Either unplug the batteries and use a wall mounted power supply (12 volts) or use the batteries. No power in the Tx, no signal out. Unplugging the crystal really has nothing to do with it. The signal that comes out of the Tx through the buddy or trainer jack in the back, is identical to whatever you are going to transmit if using it to control a real model. Removing the crystal will only affect the transmission of a signal over the antenna. It has nothing to do with the signal line coming out of the trainer jack as far as I can tell.
I am going to take the Zhen Hua transmitter apart and its cable. I will then post the appropriate pins and their functions. It is still very much unclear to me as to why all other channels work, except the throttle channel. Anyone encounter this? Fixes? By the way, I should be receiving a PIC-Serial interface cable in a few days. I will post the results.
For anyone very much into smaller RC planes or heli's, then check out the new Spektrum DX6. For $200.00, you get a six channel digital computer radio, operating at 2.4 GHz. Just read the specs and you will see why this will be the very best radio you could possibly have for the money. I will be purchasing one very soon. It comes with four sub-micro S75 servos and a dual receiver. Perfect for park flyers and small heli's.

THrottle should work with the 6channel. It takes a little playing around with PPJOY and the settings to get working OK.
