AS39513 − Detailed Description

Set Password Command

Set Password Command Request:

Set Password Command Reply:

The Access Level Field Level has the Format Below:

where:

ALEV[1:0] – Access level.

0 = Not allowed.

1 = System access level.

2 = Application access level.

3 = Measurement access level.

The set password command changes the password for the

access level specified in ALEV, but only if the access to that level

has been opened by the Set Access command. For example, to

write the System password, system access must be allowed. If

an attempt is made to set a password for an access level that is

not open, the AS39513 will respond with an error code 0xA0.
