CG-ARM7/D/E CAN/CAN Gateway

EMS Dr. Thomas Wünsche

Using a password, the gateway can be protected against

unauthorized access. If the key is not defined or the value is set to 0,

password protection is disabled. The password is an up to 14-digit

hexadecimal value.

The password protection supports two security levels.

For the highest level the most significan bit (56th bit) of the password

must be 1. This security level prevents any communication with the

gateway, if the device has not been unlocked with the correct

password before.

If the most significant bit is 0, reading out information about the

gateway is enabled. Changing the configuration however is not

possible.

Example:

# Security: high

password=80 07 05 AF D6 B0 D1

# Security: normal

password=00 07 05 AF D6 B0 D1

This key specifies the period of time in milliseconds, which will pass

by until the gateway gets bus on again after a bus off condition has

occured. If this value is not defined, the device remains in bus off

state. If a bus off time of 0 milliseconds is set, the gateway tries

immediately to get bus on again.

Example:

busoff=100
