This function can be used to produce phone charger cable too. Volcano's upper panel controls phone connector GND and VCC, which ensures phone to work normally and coordinate with box software analysis to detect charger-pin accurately. All these experience has been proved and tested over years. Firstly, there is no way to find out phone charger-pin secondly, even when you know charger-pin and set it to higher level, phone will directly reduce it because of heavy current, as a result, it fails to play the role of higher level as well as abnormal of phone detection/read/write operations. When setting higher level to general SCM can only provide the current of 20 Ma. If you cannot find phone's charger-pin accurately and set VCC definition to it, phone will not respond to Read/Write operation at all. Because many phones can't work normally without GND and VCC, especially for MSTAR cpu phones. Completely GND and VCC control functions After years of practice we found out that box would have problems of no GND and VCC hardware design.It's impossible to collect and analyze analog data when there is no digital resistance. Our box can detect phone connector GND and VCC accurately even without power supply from clippers, wich means to realize detection and phone Read/Write possible when phone connector has VCC and GND definition at the same time without clippers. At the same time, the functions of connector GND and VCC are accurate too. It can analyze the accurate resistance value of USB D+ pinout this to define USD definition precisely. Digital resistance It achieves to pull up/down any resistor, this performs important role when detecting USB definition.

This product brings China phones servicing into new level, why ? There are exclusively many new functions that are available only in Volcano box like Digital resistance (It achieves to pull up/down any resistor, this performs important role when detecting USB definition), Completely GND and VCC control functions (Volcano's upper panel controls phone connector GND and VCC, which ensures phone to work normally and coordinate with box software analysis to detect charger-pin accurately), Set pull up/down to any pinout (you can set any pinout up/down with a variable resistance value on TX from 5 to 10K) as also Internal powerful CPLD. Volcano Box it's new product from world know Furious Team that supports China phone.
