Clear any Errors
GR
If Ethernet messages are not enabled, the last event or error number can be read by this
command. Any error displayed on the unit is cleared, so if there was a lighting error, the NL-
2XX will resume auto-sensing on that channel.
The reply will be in he same form as the GT command above. If there are no outstanding
events or errors, then only the prompt ">" is returned.
Set/Clear the Webpage Password
EY
EY asc1, asc2, asc3, asc4, asc5, asc6
This command sets the password required to access the webpages. If EY is entered on its
own then the password is cleared. There are six optional parameters, which are decimal ASCII
values for a password from one to six letters. A value of 65 is 'A', 66 is 'B', etc to 90 is 'Z'.

In some applications it may be necessary to lock the keypad so that un-authorised operators
cannot change the settings.
A unlock code can be set. This can be used as a low-security way of allowing trusted users
to unlock the keypad. Ethernet commands and the web pages still work. The setting of this
command is restored after a power cycle.
