(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.
