PRELIMINARY

Preparing the MLC for front panel lockout

To allow access to front panel changes to speciﬁ c personnel while the front panel is

locked, you can set a user and/or administrator PIN and set which type of PIN, if

any, is allowed to unlock the panel.

Setting up and enabling or disabling PINs

1. Install and start the Extron Global Conﬁ gurator (GC) software. See chapter 4.

2. Open an existing GC project or start a new project. Refer to the GC help ﬁ le or

the MLC 226 IP Series Setup Guide for instructions.

3. In the IP Link tab area on the left side of the screen, click on the name of the

MLC you want to set up.

4. Click on the Advanced Configuration tab.

5. Select which PIN to enable (which PIN will be allowed to unlock the front

panel), or disable both PINs so that no one can access the front panel during

front panel lockout.

6. Type in the four-digit PINs for the administrator and for users. Each digit of

the PIN must be a number from 1 to 6 because they represent the MLC’s six

input buttons, which will be used as a numeric keypad. By default, both PINs

are set to 1346.

7. Complete the rest of the conﬁ guration, then save

the project: click File and then Save or click the

Save icon, shown at right.

8. Upload (build) the conﬁ guration to the MLC.
