R260S - Instructions
Motorola/Freescale MC912-9S12-9S12(Xgate) in-circuit
Programmer
Introduction:
R260S Programmer can program the Motorola/Freescale 68HC912/MC912/MC9S12
microcontroller families, including the latest MC9S12X XGATE-based processor family. The
system works as a in-circuit programmer, no needs to remove the chip from the target board nor
lifting any pin. It connects to the board via serial connection by using only few wires and it works
with secured chips, too. No matter if secured or not!
Installing and using instructions:
1. Install the software located in the CD on a PC running Windows (95,98,Me,XP tested).
2. Attach the R260S dongle to the PC RS232 communication port.
3. Connect the wires to the board as explained in the pictures. In some cases you need to leave
the green wire unconnected... in that case, please, be careful that the wire does not touch the
board inadvertently.
4. Run the PC application software and select the desired model of the car you need to
program.
5. Power up the interface with a +12Vdc regulated supply.
6. Press “Read” button to read the micro, after the decoding phase you can read the decoded
old-value.
7. Type the desired new value and then press the “Write” button. After the writing phase the
system checks automatically that the new value has been written correctly to the eeprom. If
desired, you can read again the newly programmed value.
8. Switch-off the power supply after programming. Be sure that the power has been switched-
off before disconnecting the programmer from the target board.
Notes:
•
If you see the value –1 in the read field maybe you found a new sw version or you selected the
wrong software.
Warnings:
•
Please, do not extend the thick black cable for any reason! If you do so, you will loose the
calibration.
