**Things to prepare [#qca4996c]
You need the items below to operate G.I.M.I.C:~

***USB Micro-B cable [#dd6420e9]
To connect G.I.M.I.C to your PC. G.I.M.I.C also draws power from USB.~
A low-quality cable may cause signal degradation or power loss, which in turn can lead to unexpected malfunctions.~
Use a cable that can fast-charge a smartphone to avoid such troubles.~

For reference, below are the cables we employed during the development.~

Straight~
Motorola ECOMOTO : SKN6378A~

Right angled~
Sony Ericsson : EC600L~

'''Note that some cables shipped with smartphones or tablets are &color(red){"charge-only", i.e. unable to transfer data.};'''~
'''Make sure that your cable offers data transfer too.'''~

***A microSD card (if you use the "Standalone" G.I.M.I.C firmware) [#pddecfb0]
From which G.I.M.I.C reads song files.~
G.I.M.I.C can handle SD/SDHC cards with up to 8GB capacity (SDXC cards are unsupported).~
***A microSD card (optional) [#pddecfb0]
From which G.I.M.I.C reads song files when in standalone mode. You don't need one when your G.I.M.I.C plays songs on your PC via USB.~
G.I.M.I.C can handle SD/SDHC cards with up to 32GB capacity (SDXC cards are unsupported).~

We have confirmed that UHS-I cards can be used, but they will function in compatibility mode, since G.I.M.I.C doesn't support UHS-104.~

For reference, below are the cards we employed during the development.~

SanDisk MobileUltra microSDHC UHS-I 8GB : SDSDQY-008G-J35A~
SanDisk Extreme Pro microSDHC UHS-I 8GB : SDSDQXP-008G-J35~
SanDisk Extreme Pro microSDHC UHS-I 16GB : SDSDQXP-016G-J35~

***A pair of headphones, earphones, or other loudspeakers [#ocb3d4f6]
G.I.M.I.C outputs audio signals through a 3.5mm mini-stereo jack. Apply adaptors as needed.~
Recommended impedance range is from 16 Ω to 300 Ω.~
Recommended impedance range is from 16 Ω to 300 Ω for the Pro/Std motherboard, 16 Ω to 32 Ω for the Lite motherboard.~

In addition, the pro model (GMC-MB2PRO) can be connected to a breakout cable, which will provide an output through 6.5mm phone jack. See below for details.~

***A breakout cable (for GMC-MB2PRO only; optional) [#rd9a8eb9]
This provides additional I/Os, namely:~

-A 6.5mm phone jack (referred above)
-Line OUT x 4 (STEREO 2 paths)
-MIDI I/O (for future projects; currently without use)

We recommend using either the 6.5mm phone jack or the line-out, since they  give you a better sound quality than the 3.5mm mini-stereo jack.~

Be sure to use ALVA Babyface (BF-BOCMKH). Use of other cables is unsupported.~

***An AC adaptor (for GMC-MB2PRO only; optional) [#y71e83ac]
Drawing power from an external supply, you can avail yourself of G.I.M.I.C's full potential.~
Use an AC adaptor with an output voltage of 5V, a currency of 1000mA (or above), connector type of EIAJ-02.~
Use an AC adaptor with an output voltage of 5V, a currency of 1000mA (or above), connector type of EIAJ-02, center positive.~

''Do not use an AC adaptor with an output valtage exceeding 5.2V, as it can cause permanent damage to G.I.M.I.C.''~
''Do not use an AC adaptor with an output voltage exceeding 5.2V, as it can cause permanent damage to G.I.M.I.C.''~


For reference, below is the AC adaptor we employed during the development.~

AC adaptor for SONY PSP1000/2000/3000 series: PSP-100~

2: Line I/O
2: Line I/O~
We adapted BF-BOCMKH for our particular use, so that the "Line IN" actually works as another set of OUTPUTS.~

-Parallel-out OFF (default)~
Line IN : outputs no signal~
Line OUT: outputs all audio signals (PCM and other sounds mixed together)~

-Parallel-out ON~
Line IN : outputs audio signals from the module currently loaded (i.e. all audio singals except PCM)~
Line OUT: outputs PCM sounds~

Output signal from the "Line IN" port bypasses G.I.M.I.C's internal preamplifier. This is better suited for use with a high quality audio interface.~

3: 6.5mm phone jack~
Use this instead of the 3.5mm jack on the motherboard for a better output.~

4: Connector to GMC-MB2PRO~

**Before You Start [#tfc1e19e]
There are a few steps to follow before you start up your G.I.M.I.C for the first time.

***Updating the Firmware [#x4cad2a7]
Please update the G.I.M.I.C firmware to the latest version, following [[the instruction here>Firmware Update]].~

***Installing the Driver [#dac0c7a4]
For your PC to recognize G.I.M.I.C as a USB Device, it either needs to be running Windows8, or have the G.I.M.I.C driver installed. If you are using Windows7 download and install the driver from the link below.~

-G.I.M.I.C driver ver. 2013/05/23: &ref(gimic-win-driver-20130523.7z);~
// この箇所、ドライバ更新に合わせてアップデートすること
After extracting the .7z, run &color(red){dpinst-x86.exe}; if your OS is 32-bit windows.~
Users of 64-bit OS should run &color(red){dpinst-amd64.exe}; instead.~

***Preparation for third-party applications [#j10a104c]
You need to install c86ctl to be able to control G.I.M.I.C from third-party applications.~
Download the latest version from the link below.~

-c86ctl v1.4.4 (2013/10/13): &ref(c86ctl_1.4.4_32bit.zip);~
// c86ctl 更新に合わせてアップデートすること
Copy the extracted c86ctl.dll to the same directory as the third-party application is in.~

Also, c86ctl depends on Visual C++ 2010 Runtime. Install the package below, and update to the latest available version using MicrosoftUpdate. Note that you need to install 32-bit version of the components (files with _x86 in their names) regardless of your OS version.
-[[Microsoft Visual C++ 2010 SP1 Redistributable Package (x86):http://www.microsoft.com/en-us/download/details.aspx?id=8328]]

***Preparing Song Files [#x7acd568]
You can find song files to be used for test purposes [[here>テストデータ]].~

When G.I.M.I.C is in USB mode, files can be played from third-party applications. [[Here>USB制御FW - 対応ソフト]] is the list of applications that support G.I.M.I.C.~

G.I.M.I.C can also play songs without the aid of external software. In that case, the song files must be contained in the SD card inserted in G.I.M.I.C's card slot. If your SD card has a capacity of 16GB or above, it is recommended to initialize the card before copying songs, with allocation unit size set to 4096 Byte or 8192 Byte, file system FAT/FAT32, for more efficiency. ((Initializing an SD card will delete all the data currently contained in it, so make backup beforehand as needed.))

**Controlling G.I.M.I.C [#yee9eee8]
Before you start operating G.I.M.I.C, please update its firmware to the latest version, following [[the instruction here>Firmware Update]].~

The firmware comes in two flavors: Standalone and USB-controlled.~
The way G.I.M.I.C is controlled varies depending on which firmware is installed.~
G.I.M.I.C can operate in two modes: Standalone mode and USB mode. At the time of start-up, G.I.M.I.C looks for an SD card in its slot. If it finds one, it will start operating in Standalone mode. Otherwise it will operate in USB mode.~

The way G.I.M.I.C is controlled varies depending on which mode it is operating in. You will find detailed information later in this article.~

***Connecting to the power source [#j48c22df]

Connect G.I.M.I.C to a PC via USB, or to an external power supply through an AC adaptor. When connected, G.I.M.I.C will be in standby mode. GMC-MB2PRO's relay gives one small click.~
Connect G.I.M.I.C to a PC via USB, or to an external power supply through an AC adaptor (Pro only). When connected, G.I.M.I.C will be in standby mode. GMC-MB2PRO's relay gives one small click.~

-When AC adaptor is connected before USB, the STATUS LED will light up for about 0.5 seconds, and a circuit will be activated to cut off noise originating in USB, for the betterment of the sound quality.~

-Note that G.I.M.I.C determines whether its power is supplied through an AC adaptor or through USB at this point: connecting the AC adaptor while G.I.M.I.C is running on USB bus power does NOT switch the power source.~

***Connecting to a PC (Standalone firmware) [#g4ce196e]
***Standalone mode [#g4ce196e]
'''This section is an abstract from a more fully detailed description in Japanese. You can read the original [[here>スタンドアロンモード]]'''.

***Connecting to a PC (USB-controlled firmware) [#p7b406d9]
***USB mode [#p7b406d9]
'''This section is an abstract from a more fully detailed description in Japanese. You can read the original [[here>USB制御モード]]'''.

-Make sure that there is no SD card inserted in the card slot (otherwise G.I.M.I.C will start up in Standalone mode). You can force Pro/Std motherboard to start up in Standalone mode, ignoring the SD card in the slot. To do so, press the power switch while pressing the jog wheel in.

-Press the power switch.~
Power/Status LED will light up and G.I.M.I.C's OS will begin starting up.~

-When the OS has successfully started, the PC will recognize G.I.M.I.C as a USB device.~
If it's the first time you connect G.I.M.I.C to the PC, you may be required to install a driver.~
If it's the first time you connect G.I.M.I.C to the PC, you may be required to install a driver. (See above)~

Those who use WindowsXP, Vista or 7 need to download and install the driver from the link below.~
--G.I.M.I.C driver ver. 2013/05/23: &ref(gimic-win-driver-20130523.7z);~
// この箇所、ドライバ更新に合わせてアップデートすること

After extracting the .7z, run &color(red){dpinst-x86.exe}; if your OS is 32-bit windows.~
Users of 64-bit OS should run &color(red){dpinst-amd64.exe};.~
(Windows8 has a necessary driver already installed, so you can skip the step above.)~

-Launch any applications that support G.I.M.I.C~

You need to install c86ctl to be able to control G.I.M.I.C from third-party applications.~
Download the latest version from the link below.~

--c86ctl v1.4.4 (2013/10/13): &ref(c86ctl_1.4.4_32bit.zip);~
// c86ctl 更新に合わせてアップデートすること

Copy the extracted c86ctl.dll to the same directory as the third-party application is in.~

Also, c86ctl depends on Visual C++ 2010 Runtime. Install the package below, and update to the latest available version using MicrosoftUpdate. Note that you need to install 32-bit version of the components (files with _x86 in their names) regardless of your OS version.

--[[Microsoft Visual C++ 2010 SP1 Redistributable Package (x86):http://www.microsoft.com/en-us/download/details.aspx?id=8328]]

***Using the Jog Wheel (USB-controlled firmware) [#vd3fc96e]
-Using the Jog Wheel~
Turning the wheel changes output volume.~

Pressing the wheel toggles parallel output on/off. Each time you press the wheel, the STATUS LED alternately turns on/off. This indicates whether parallel output is currently enabled/disabled.~

|>|>|Parallel Output|
|STATUS LED|off|on|
|Line IN|unused|audio signals from the module|
|Line OUT|all audio signals|PCM sounds|

***Turning off your G.I.M.I.C [#se9be492]
Press the power switch to cut off the power. G.I.M.I.C will turn back to standby mode.~
Press the power switch to cut off the power. G.I.M.I.C will turn back to standby mode. Std/Pro motherboard memorizes the volume setting.~

G.I.M.I.C continues to consume a small amount of power while in standby mode, so unplug the USB cable and/or the AC adaptor as needed.~

***Supplementary Information [#ia61c357]
-Breakout cable's Line "IN" and OUT: which to use?~

Line OUT is generally better suited for connection with audio equipment. It outputs PCM sound from motherboard and other audio signals from the module mixed together, which come through G.I.M.I.C's preamplifier.~

Line IN is better suited for connection with a high-spec audio I/F, since the output bypasses G.I.M.I.C's preamplifier.~

-Output volume is memorized when G.I.M.I.C is turned off.~

Turning the jog wheel to the right increases the volume, while turning it to the left does the opposite.~
When G.I.M.I.C is cut off from power source for a certain amount of time, the volume setting is initialized to 25% of the max value.~
