I have a PIC interface for FMS with my Hitec radio that does not work with Win2000. Are there any none problems......or do I have something wacky going on. An yes I have checked all the connections etc. Im stuck.......help me out here

There are two types of PIC Interfaces. Below, the setup procedure:

Connect the interface to your PC & transmitter.
With crystal removed, turn on transmitter.
Open FMS, and under Control, select Analog Control.
Select PIC Serial Interface.
Click on Resources.
Select the correct COM port.
Select 19200 Baud.
Click Ok.
Click on Mapping/Calibration.
Click Calibrate, and follow on-screen calibration procedure.
Your interface should now be calibrated.

If the movements are irratic or no response, try to select 9600 Baud, and try recalibrating the interface.

To test your interface, you can download the Test Software from my web.

If above does not work, it might be that your interface is faulty, or maybe your PC is fitted with a new generation COM port, which the voltage levels are below 4.7V.

Hmmmmmmm. ok Ill dl that i dont think the interface is bad it has a brand new board. What can you do if you do have the low voltage COM port? Im not getting any movement at all when i try too calibrate. I have a Hitec Eclipse BTW. Thanks Dan

If your serial port voltages are too low, you will need to power the interface from an external power supply. Have a look on my web under interfaces. My Serial PIC Interfaces includes circuit diagrams for both internal and external power supplies. The external power supply can be between 5 and 12V DC, please remember to observe the correct polarity.

Basically, you disconnect the wire on the board going to pin 7 of the serial plug (supply from PC), and ensure it does not make contact anywhere.

Where this wire was disconnected, you can connect the external power supply (+) positive rail.

Alsoon the board, connect the (-) negative rail to the wire going to pin 5 of the serial port plug. Do not remove original wire.

Ok thanks a lot...It suddenly started working I have no clue why.........but thanks for the help.

Was wondering if you could help me.. I have a futaba 6xsuper pcm/ppm - and I cant get any sort of response using it in fms. Nothing at all. I am running win2k and have the latest fms... Any ideas??

why do you say wont work with win2k- maybe its related to my mess?>>?

Speak to you soon.

Scimitar, let us know what type of interface you are using, then we can maybe help.

I am using a serial interface.

I'm using the PIC & USB FMS interfaces with my Futaba FF9 without any problems. I'ne got the interface at:

in UK.

Scimitar, there are two types of serial interfaces available. One is a PIC interface , and uses a PIC microcontroller (chip), the other one, Serial PPM Interface , with only a few transistors and resistors.

The PIC interface should work on all operating systems, where the PPM interface is only compatable with Win95/98.

Do you have to take the crystal out for it to work? I have a JR 662 with a serial interface that doesn't work with fms either I have win98 I believe the interface is a ppm

With JR radios, there is no need to remove the crystal. When the training plug is inserted, the radio will turn on the coder part of the radio only, so the transmitter part will not be working.

Just remember NOT to turn on the radio at the power switch, as this will then block the signal on the training socket.

In FMS, set up the interface as follow:
Options - Analog Control.
Select PIC Serial Interface.
Click on Resources.
Select 19200 baud, and your com port in use.
Click Ok.
Click on Mapping/Calibrate.
Click Calibrate, follow on-screen instructions.
Do the channel mappings.
Calibration is now complete.

Fly plane, and see which channels must be reversed, and click on Inv under Mapping/Calibration.

If this does not work, you can try setting the baud rate to 9600 baud, as there are a few interfaces that operate on this baud rate.
