Login flow:
(Password and SECUR mode can be set from K-Config program).
1. Send SECUR? Command
2. If answer is SECUR OFF – no login needed.
3. If answer is SECUR ON – continue to login (step 4)
4. Send LOGIN USER, PASSWORD
5. Device will start to work normally.
6. If communication is not active for more than 5 minutes – UDP socket will be closed and device will logout automatically so you will
need to LOGIN again.
7. To eliminate automatic logout – you can send any command (for example Handshake) from time to time.
8. On program exit send LOGOUT (If not – device will automatically logout after timeout).
Password sessions:
Login with user or admin password will open a match session, so it is possible to continue entering commands without re-login until connection will
terminate.
For Ethernet connection, sessions will be opened while socket connection is live.
For Serial or USB connection, session will live until time-out will reach.
* To reset admin password you need to factory reset all the device data.
