But you can try to find another device/converting cable called "USB to TTL converter". It convert USB to UART/TTL level (about 5V), and can fit the signal voltage of MINI-Z ASF(but not AD band & dNaNo). It is not very easy to buy, but you can find them on some website like this:
http://www.ftdichip.com/Products/Eva...s/TTL-232R.htm


You may need to link the VCC & SIGNAL pin with a 4.7k resistance for this cable, or MINI-Z will think you don't connect anything on it. But the problem is...I can't make sure it will work or wont, for I have never got this device before.
This was what I was thinking about doing, but shorting the Rx and Tx pin's with a 4.7k - 10k resistor...

The cable I was looking into buying was this one:
http://export.farnell.com/ftdi/ttl-2...questid=430655

It should work, but i can't give you any guarantees...

dabinn, do u know it this thing might work?

http://my.farnell.com/ftdi/usb-rs232...tor/dp/1686451
and here's the data sheet
http://www.ftdichip.com/Documents/Da...2_PCB_V101.pdf

the thing seems to drop the voltage down too but at what voltage does the ASF board works when connected to the computer?

We're thinking about the same thing.
I think it should work,too. But somebody needs to try out.

Hi,
If you use this "USB RS232 to converter", you still need a I.C.S.cable for converting MINI-Z singal into RS232 voltage level at first.

Hi dabinn,

Just to confirm few things before my parts arrive and start on this lovely project:


VCC - Red wire is from 1k Resistor
SIG - White wire is from 39k resistor
GND - Black wire is from E leg of both transistor and diode

and just wondering why kyosho's only have 2 wires SIG and GND?

Thanks.

Looking to the converter shcematic and the foto, Vcc, Gnd and Signal seem to be right.

As for the 2 vs 3 wires, with only two wires like Kyosho has, you need to have batteries in the car to use the ICS, with the 3 cable setup, the computer alone can suply the power to the board

That would be a cable for the new I.C.S USB adaptor. The USB one outputs fixed singal voltage (maybe 3.3v or 5v) to mini-z, and doesn't concern about what voltage of Mini-Z is, so only two wires are needed.

The old I.C.S. cable uses a diffrent way. It can "generate" various singal voltage according to opposite VCC.
ex. When PC sends a 12v signal through the RS232, this signal triggers the transistor to make the VCC of MINI-Z flow into the SIG line. So mini-z will get a signal that with the same voltage of it's own VCC. Voltage is been converted and meanwhile the signal is been transfered.

You are right. An additional VCC line can supply the power from the PC.
But for some safety reason, we didn't modify the circuit to do that. Batteries in the car are still needed for this cable.

Do you mean the function like my ICS box?

yup.on the old millenium pro it has a place for the cable to plug in to. now if you can do it it would be awsome

i have a problem with the ICS, it seems that the pc doesnt detect the car...
im using the DIY cable with a RS232 to USB converter and only the USB to serial converter were detected on my pc which i checked on the device manager.

few Q's here:

1. how do i know it the cable i built is working
2. do i need to turn on the power?
3. how will the red LED lights up?
4. how to know if its connected to the PC
5. anyway to check of the DIY thing working correctly
6. which is the most important component of this ICS? transistor?

Thanks.

1) If it worsk its OK :P
2) Put in batteries in the car, Turn on the car while pressing the pairing button. The LED should light up.
3) just ON
4) In the program change a setting, then write to the car, press the reset button (the seting you changed will go back to default) and read from the car. The setting should go back to what you made it.
5) See point 4
6) all of them.

Do you have the manual downloaded ? It discribes how you now wich com port to use. Maybe check that to.

Good luck
