Okay i have this ESC:

The VFS Series C2 (Competition 2)
Key Features
• On Resistance: 0.00048 ohms
• Battery: nicad, nimh, lipo (no lipo cutoff)
• Control method: Changeable control
• The maximum peak current:3120A (FET specs.)
• Continuous, maximum current: 780A (FET specs.)
• Accessory: Ultimate Shotki Diode Single, Ultimate Condenser, 12 GA
• Size: 28.0x25.0x14.4.4mm (size of case)
• 18.8g in weight (The silicon wire excluded)
• Proper power-supply voltage: 4.8-8.4V (4-7 cells)
• Drive frequency: 0.9-12KHz (64 steps)
• Output voltage for receiver: 6V (input 7.2v)
• Output current for receiver: 2A (maximum peak)

According this link http://www.kopropo.com/america/index.php?option=com_content&task=view&id=82&Itemid=140 it is programable with a serial or USB ICS datacable. PC interface KO-61012 (Serial), PC interface KO-61018 (USB), Multi setting adapter KO-61009 (Stand alone programmer)

At the moment i am NOT interested in the USB data cable b/c i think all it is is a USB to Serial Cable Module. http://www.shopatron.com/product/part_number=61018/166.0.1052.56.0.0.0

Rather i am interested in this thing the Serial Cable Version.

From looking at the picture it looks like a simple Serial Adapter into 3 wires.
3 wires will plug into the ESC via its cable that originally goes into the Reciever.

This is my theory of how the KO PROPO Software ICS (Serial Port)Communicates with the ESC
http://www.airborn.com.au/serial/rs232a.gif

Computer >>> Serial Port adapter >>> unknown Cable wireing >>> 3 pin connector on ESC

When you look below in the link the ICS Module whan it talks to the ESC or Servo it displays RX and TX which makes me think it only uses 2 leads as above stated.

Can someone that owns a KO PROPO Serial Adapeter verify that to me ?
I see the adapter has 2 screws on it, so it should be easy to diasmble and reasemble w/o damage.

I really don't want to pay 75 USD for a Serial loop adapter if i can make one myself for 5 usd.

The software can be freely downloaded here.

I understand you and also have same interest.
But it may be a little more difficult.
I have the serial adaptor for GM Genius esc. Are also programmable with PC but inside serial connector are tiny smd components (transistors and pull up resistors I think)
And de Ko adapter seems to be the same. Remember to see a pic in google of the inside and also have smd parts. For sure can be DIY but need more work.
This price is abusive. :mad:
