a cable connection. In open areas, the working range of the transmitter through BT
communication is up to 328 feet (100 m). The working range of 2.4G Wi-Fi
communication is up to 328 feet (100 m) while 5G Wi-Fi is up to 164 feet (50 m). If the
signal is lost due to being taken out of range, communication will be restored once the
tablet is within range.
Measurement Capability
The VCMI device is designed with the functions of multimeter, oscilloscope, signal
generator and OBDII communication line inspection. The parameters such as voltage,
resistance, current, signal frequency, and voltage-time characteristic of the signal can
be measured and the results are displayed on the tablet.
Programming Capability
The VCMI device is a D-PDU, SAE J2534-1 & RP1210 compliant PassThru
programming interface device. Using the updated OEM software, it is capable of
replacing the existing software/firmware in the Electronic Control Units (ECU),
programming new ECUs and fixing software-controlled drivability issues and emission
issues.
2.2.2 Power Sources
The VCMI device can receive power from the following sources:
 Vehicle Power
 AC/DC Power Supply
 Built-in rechargeable Battery Pack
Vehicle Power
The VCMI device operates on 12/24 Volt vehicle power, which it receives through the
vehicle data connection port. The device powers on whenever it is connected to an
OBD II/EOBD compliant data link connector (DLC). For non OBD II/EOBD compliant
vehicles, the device can be powered from a cigarette lighter or other suitable power port
on the test vehicle using the auxiliary power cable.
AC/DC Power Supply
The VCMI device can be powered from a wall socket using the AC/DC power adapter.
Built-in Battery Pack
The VCMI device can also be powered with its built-in 3750mAh battery pack.
