Remote Access
Since firmware Ver.2.00 a web server is set up - however in japanese. Initial login is
ユーザー名 (loginname): root
パスワード (password): password
The web server allows you to configure your account data more easily than with the remote control. Unfortunately this login and password is not working on the serial console. With a root access account one might be able to add english translations.
No other services seems to run as all ports are closed.
Hardware Disassembly
WARNING ! Disassembling the VGF-CP1 may cause damage ! It's on your own risk !!
remove two screws to seperate acrylic glass
- To open the nice housing, you first have to remove two white square shaped sticker on the lower back side. The screws fix two white bushings, which have to be taken out in order to seperate the acrylic glass base.
remove sticker to open cover
- Next you have to remove a rectangular white sticker. which is used as a diffusor for the blue led.
slightly shift display in arrow direction
- To seperate the cover, you have to move carefully the display towards the direction marked with red arrows. The ribbon cable is on the bottom side, so you can open the housing now.
next remove 6 screws to open shield
- The PCBs are shielded with a blank sheet fixed with six screws. For those you need well fitting screw driver, because the four ones marked in red are tightend very hard. I had to drill them out !
mainboard with display connector
- Front display is connected to ribbon connector (red square). Another pwr button is inside (blue marking), next to it a reset button (green marking).
UART1 serial connector
- A serial console can be connected through UART1 CN853. I already soldered another plug on top of the original one. Pinout see below. You'll need a level shifter LVTTL-to-RS232 as well in order to connect a PC serial port.
- LVTTL/RS232 - Building a Custom Serial Interface http://buffalo.nas-central.org/wiki/Building_a_Custom_Serial_Interface
Pin 1 of the connector the left one on the picture and it is marked on the PCB with a white dot.

| 1 | Power (3.3V)* |
| 2 | Transmit (TX) |
