- SCON-KIT/PRO is a serial console connection kit for KURO/BOX/PRO
- You will need a SOLDERING IRON for this kit
- The chance of guarantee is only for the first time when it does not work
- The term of guarantee depends on the store

|USB Type A||<-->||USB board FTDI FT232RL|| ---TXD-->
|KuroBox Pro Daughterboard|
Scon Kit Pinout
KuroBox Pro UART0 Pinout
Attach a Serial Header to the Daughterboard
- Do not insert/extract or push/pull attached connector frequently
- Do not put stress on connector and base
- Do not attach connector when the power of KURO-BOX/PRO is on
- You will need terminal software
Attach Serial Header to circuit board by soldering iron make sure the AC plug is off.
- Open front panel of KURO-BOX/PRO, take the HDD daughter board out.
- Put the serial header onto UART0.
- Make sure pin No.1 match to TXD.
- Attach with a soldering iron from the back of the base.
- Put the daughterboard back onto the KURO-BOX/PRO
Use the SCON-KIT as a USB/TTL converter
Connection of SCON-KIT/PRO
- Connect SCON-KIT/PRO and UART0 on the sub base of KURO-BOX/PRO by using a patch cord
- Do not connect to the PC yet.
Preparation of appropriate COM port driver and install
- download the appropriate COM port driver for FT232R from the URL below
- Connect the SCON-KIT/PRO to the USB port of PC. Install the driver which you downloaded.
- Open Device manager and check which COM port is used. For example in the picture, port is named COM5.
Set up the terminal software
- Start terminal software. See KURO-BOX/PRO UART specification set up serial port. Use your COM? port for setting.
Example: the way to setup using “HyperTerminal” in WindowsXP/2000
- start “hyperterminal” and register a name of the new connection
- connection method: chose COM? which you checked before
- see KURO-BOX/ PRO UART specification and set up the port
- you can see this picture when you start KURO-BOX/PRO
|sometimes, you may get the junk/Trash data when you turn the power on/off or reboot, but it is not abnormal. If you cannot return, reset the terminal software or reconnect.|
Use a different Serial Converter
The serial port signals from the processor are only 3.3V. For proper RS-232 12V signaling, an RS-232 level shifter needs to be added. These are very common in PDA serial cables also, but can be purchased
Build your own LVTTL/RS232 or LVTTL/USB interface
- LVTTL/RS232 - Building a Custom Serial Interface
- LVTTL/USB - Use a Nokia Serial Cable on an ARM9 Linkstation
- LVTTL/USB - Use a cheap phone sync cable with the serial port
Buy your own TTL Level Shifter
- LVTTL/RS232 - MAX232 based from Futurelec - MINIRS2323V
- LVTTL/USB - FTDI chip based cable - TTL-232R-3V3
Usage considerations for the TTL-232R-3V3
A working/tested pinout/wire-color scheme is:
- Solder the 4-pin header to the board. Make sure you don't have shorts.
- You will need to switch wires on the TTL-232R-3V3 cable. Use a sharp object to lift the plastic tabs and carefully pull the wires out. Rearrange them according to the table above (black, empty, orange, yellow, empty, empty) and slide those wires back in. Tape the other wires to make sure they don't short anything.
- When plugging in the cable, make sure black aligns with GND, yellow with TXD, and orange with RXD.
- Connect the USB cable to your computer, start a terminal program with the right settings.
- Turn on the device, you should see output from the bootloader in couple seconds.
