Volcano Box it's new product from world know Furious Team that supports China phone. 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.
Why choose Volcano box ?
Digital resistance It achieves to pull up/down any resistor, this performs important role when detecting USB definition. It can analyze the accurate resistance value of USB D+ pinout this to define USD definition precisely. At the same time, the functions of connector GND and VCC are accurate too. 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. This is exclusively on Volcano. It's impossible to collect and analyze analog data when there is no digital resistance.
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. Because many phones can't work normally without GND and VCC, especially for MSTAR cpu phones. 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. When setting higher level to general SCM can only provide the current of 20 Ma. 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. All these experience has been proved and tested over years. 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. This function can be used to produce phone charger cable too. Other box can't provide standing current over 30Ma for they only have one PCB panel. MSTAR cpu phones are difficult to achieve Read and Write on other boxes.
Set pull up/down to any pinout - You can set any pinout up/down with a variable resistance value. Lots of dead phones TX connector is OC portal, which means higher level is open-collector, it will output lower level if you don't set pull-up resistor to TX. Volcano box controls flexible pull-up resistor value by changing the resistance. For example, some OM cpu phones can't Read/Write normally if you do not set 5-10K pull-up resistor. Many other phones can't detect or Read/Write without this functions. This is exclusively on Volcano and no other box has this function.
Selects resistor value from 390 ohm -800K - Short two pins with resistor function can realize phone enter downloading mode, or other special purposes. This is exclusively on Volcano and no other box has this function.
Eagle Eye - EagleEye is used for measurements of Current. Its built-in Analog Metter and digital. It can show you how much MILLIAMPERE Mobile using. This is exclusively on Volcano and no other box has this function.
Internal powerful CPLD - Its internal powerful CPLD provides filtered signal output. All the high frequency interference pulse has no access to phone nor to computer, thus it ensures no wrong interference between phone and computer, to make it work more stably. Meanwhile, CPLD also offers more powerful driving ability as well as a wider range of voltage, making read/write to a higher rate of success. It will be very worse if box has no CPLD like read/write stability, immunity and driving ability etc.
Better software and hardware protected design - This ensures heavy output current from hardware design, but also guarantees it will not burn-out box or phone. That is because instant software current real-time monitoring as a watchdog protection, long time protection of thermal relay and over current resistance protection ensure the output current can be stabilized 500 Ma but never over 700Ma. Each pin has been designed for overvoltage protection and negative pressure protection. This is exclusively on Volcano and no other box has this function.
With a more reasonable USB pathway design - Volcano core IC on-resistance value is only 3 ohm while other box uses more than dozens of ohm. Excessive access of resistance will inevitably cause phone USB work unstably or even not work completely. Other box uses excessive resistance will not support some phones read/write and this is confirmed by the practice already.
Test battery - This function is used to have schematics for making your own cables for customers. For example, make chargers, earphone cables etc. This is exclusively on Volcano and no other box has this function.
