4.1Protocol Supported
High Speed CAN - offers baud rates from 40 Kbit/s to 1 Mbit/sec, depending on cable length.
This is the most popular standard for the physical layer, since it allows for simple cable
connection between devices. High speed CAN networks are terminated with 120 ohm
resistors on each end of the networ
Low Speed CAN - offers baud rates from 40 Kbit/s to 125 Kbits/sec. This standard allows
CAN bus communication to continue in case of a wiring failure on the CAN bus lines. In low
speed CAN networks, each device has its own termination.
Single CAN - offers baud rates up to 33.3 Kbit/s (up to 88.3 Kbit/s for high-speed mode)
J1939 CAN - is used in the commercial vehicle area for communication throughout the
vehicle with the physical layer defined in ISO 11898. Under J1939/11 and J1939/15, the data
rate is specified as 250 Kbit/s, with J1939/14 specifying 500 Kbit/s.
J1850 (PWM) - SAE J1850 pulse-width modulation offers baud rates up to 41.6 Kbit/s,
standard of the Ford Motor Company
J1850 (VPW) - SAE J1850 variable pulse width offers baud rates up to 10.4 Kbit/s, standard
of the General Motors
J1708 (SAE) - the standard defines a double-wire 18-gauge cable that can run upto 130 feet
(40 m) and operates at 9600 bit/s
4.2Getting Started
Prior to first use of the diagnostics application, ensure the VCI device is properly connected to and is
communicating with the tablet.
