1. Introduction
GCAN-600 is an automobile CAN bus decoding module, it applies to all kinds of automobiles which's ECU use ISO15765 protocol to communicate.
GCAN-600 module can receive all the CAN bus data which sent by sensors in automobile, then parse and resend it to UART serial bus. So users don't need to know much about the CAN bus protocols in automobile, just integrated GCAN-600 into their own system(SCM, PC serial bus, GPS, DVD, PND and so on), then the system can connect to automobile's CAN bus to read the sensors' data such as speed, engine speed, coolant temperature, battery voltage and so on.


2.   Properties
1) Module can receive data through OBD port
2) Support almost all the automobile that use ISO15765 protocol
3)  All the sensors' data decoding by the module itself
4) UART serial bus send data with ASCII
5) Mileage, fuel consumption, DTC can be read
6) Driving habits can be computed
7) Two kinds of working mode.(introduced in chapter 3)
8)Support on-demand customization
9)Working temperature range from -40 to 85 °C
10) Size: (L)18 mm * (W)12 mm * (H)4 mm

3. Instructions
General type of GCAN-600 module support two kinds of working mode.

A: auto mode
In this mode, users only need to send one command to the module by serial bus, the module will send a long data flow every second.(Such as table 1)

B: interlocution mode
In this mode, users can send a specific data to the module to read only one sensor's data by serial bus, the module will send the sensor's data once.(Use PID in table 1)
 
GCAN-600 module send data start with "$OBDRT=", the following examples are all used auto mode.
