ISO Raw

The general flow with ISO Raw Expert Mode (‘e’<4>), is:

1. Select a baud rate

2. Output bytes and optionally receive bytes

ISO Raw mode is different in that there is no understanding of packets or filters. It is

intended for cases where less conventional ISO 9141/KWP 2000 packets/communication

are being used or for alternate vehicle protocols, like MUT and SSM. The export mode

commands to accomplish these tasks are:

Command ‘R’ – Set the Protocol Rate

Sent: 2 bytes

{

U8 Cmd; // ‘R’

U8 Rate; // 1=19200

// 2=15625

// 3=10400

// 4=9600

// 5=4800

}

Responds: 1 byte

{

U8 Result; // Should match ‘Rate’ requested

}

Notes: ISO has a default rate of 10400 (3), which is correct for

ISO 9141 and KWP2000.

Command ‘r’ – Get the Protocol Rate

Sent: 1 byte

{

U8 Cmd; // ‘r’

}

Responds: 1 byte

{

U8 Result; // Current rate

// 1=19200

// 2=15625

// 3=10400

// 4=9600

// 5=4800

}

Notes: The default rate when you enter this Expert Mode is 10400.
