3.7.7 Setting or Changing the Password

Set Password

To set a password, follow these steps:

  1. Send the CNFG_SetPassword command through Endpoint 0x05 (OUT).
  2. Provide an eight-byte password.
  3. Read the response through Endpoint 0x85 (IN).

Possible responses include the following:

  • The command is accepted and the password is saved
  • The command is rejected due to invalid password parameters
  • The command is rejected because the configuration is permanently locked
  • The command is rejected because a password already exists

If the response is rejected because parameters are invalid, retry with a password that has eight characters.

If the response is rejected as password already exists, try recalling the previously set password.

If the response is rejected as configuration is permanently locked, neither the password can be set nor the configuration can be changed.

If the response is accepted, the password is set. Once all configuration is complete, lock the configuration.

Change Password

To change an existing password, follow these steps:

  1. Send the CNFG_ChangePassword command through Endpoint 0x05 (OUT).
  2. Provide:
    • The current eight-byte password
    • The new eight-byte password
  3. Read the response through Endpoint 0x85 (IN).

If the configuration is locked, unlock it before attempting to change the password.
