OBD-II

Protocol

OBD-II Protocol

There are five signaling protocols that are permitted with the OBD-II interface. Most vehicles have been

implemented with only one of the protocols. The AX5 features a superior protocol detection algorithm that

ensures the device connects reliably even to vehicles that do not fully conform to the OBDII standards. The

AX5 supported all legislated OBD-II protocols below:

z J1850 PWM (Ford vehicles)

z J1850 VPW (GM vehicles)

z ISO9141-2 (Asian, European, Chrysler vehicles)

z ISO 14230-4 KWP

z ISO 15765-4 CAN (11/29 bit ID,250/500 Kbaud)

The AXTool has an “OBD Live Data” viewer for showing OBD data in real time. See Section 4.2 for detail

descriptions.

Micro USB Connection

The Micro USB can supply power to the AX5 device for parameters setting or firmware upgrade purpose.

When micro USB is connected to your laptop/PC and main power is not applied, the OBD-II and GSM/GPRS

functions will be turned off temporarily.

Buzzer

Operation

Buzzer Operation

The internal buzzer of the AX5 can be configured by any events or triggered by remote GSM/GPRS server.

Supply

Power Supply

The AX5 device connects to the OBD-II SAE J1962 connector of vehicle and draws power from the OBD port.

No additional power cabling is required for operation. If the OBD port of vehicle is covered or you need to

install AX5 in another place for better GPS reception, the optional low profile OBD-II extension cable is

required.
