Authentication to prevent non authorized people from changing device settings the
administrator may assign passwords for either the admin and/or an
operator (same applies for talent/artist). While the admin is allowed to set
everything, an operator is just allowed to load presets. Parameters will be
reset if there was an attempt from the operator to change it.
Enable [enable / disable]
the administrator may turn authentication off.
Change Password for [admin / operator]
Select which password you will set / change
Password key in a password
Default passwords are: admin (for admin) and operate (for operator).
Repeat repeat that password
Important Note! The authentication may be enabled / disabled form the console interface as well
(see page 8 "1: Manage Password") via USB connection but also via Telnet! If you have higher security
demands you should turn the Telnet server off. Authentication will turned off and passwords will be reset if
one initializes the device to factory default (see Reboot - page 19, INIT/RESET rear button - page 4).
If there was an authentication failure, the admin
will be notified on next proper login about such conditions :
The pop up appears as often as an login failed.
Network IP address setup, see above: "Getting started – IP setup of the device via web browser"
IP Address

Gateway
Transmit Metering Data metering data will be streamed via UDP protocol. In order to receive such
data by external applications you must define ports (port range) for
matching fire wall definitions.
Enable streaming of metering data via UDP on demand of an external application
(web browser, J*AM, 3
rd
party).
UDP Port Range Start lowest port number.
UDP Port Range End highest port number.
an external application, that can not be configured prior to start up like the
web GUI will ask the LM 4 for the possible port range and will start looking
if the first port is available on the PC where the application resides. If yes it
will tell the LM 4 to start streaming on that port.
If not the application must look for next available port.
Other applications like the J*AM which have pre definitions will not ask the
LM 4 for possible UDP port range. They will use the one from the
application set up menu.
