Extron electronic MLC 52 manual No IR/232 while display power is off

•Automatically shut off projector power after being inactive for:

Click the up and down arrow buttons at the right of this field to adjust the amount of time the MLC will remain inactive before shutting down the display device. You can select periods in increments of 30 minutes. If this field contains a value, the MLC monitors its button presses; when the specified amount of time passes without a button being pressed, the MLC sends an Off command to the display device. If no amount is entered in this field, the MLC does not turn off the display unless its power Off button is pressed.

•When powering up, delay for: and When powering down, delay for:

Click the up and down arrow buttons at the right of these fields to select the number of seconds that elapse between a power button press and the display device powering up or down. When you make a selection in either of these fields, the MLC power button blinks during the period between the button press and the actual power-up or power-down.

These fields do not actually set the delay time on the display device; they reflect the device manufacturer’s settings. The blinking power buttons on the MLC let you know that the device is in the process of powering up or down, and has yet not completed the cycle.

Often, the two delay fields are filled in by the device driver when you load it to the MLC (although you can change them). If the driver does not contain this information, you must enter it yourself if you want the buttons to blink during the delay period. If you do not select a number of seconds for either powering on or off, the button does not blink during the delay.

•No IR/232 while display power is off

When this check box is selected, none of the MLC’s buttons (except the power On button) issue commands if they are pressed when display device power is off, or when the device is warming up or cooling down.

•Enable 2 second hold on Power Off button

If this check box is selected, you must press and hold the MLC’s Off button for 2 seconds in order to power off the display device. After the 2 second period, the Off button starts to blink and the projector begins to shut down. (This helps prevent accidental powering off of the projector.)

Entering display device communications port settings

The Display Comm Settings tab shows the parameters for the display device’s communications port. These fields are usually filled with information obtained from the driver when it is loaded. However, if there is no Extron driver for your display device, you must enter this information for your projector or display manually (your device user’s manual should provide these settings). If the information you enter here is not correct for your device, the MLC cannot communicate with it.

To enter the display device’s communications port settings,

1. Select the correct device settings from the Baud Rate, Data Bits, and Parity drop-down menus. When you make a selection in any of these fields, the Apply and Cancel buttons become active (red).

2. Click Apply.

(Click Cancel if you want to clear settings that have not been applied.)
