•To set up audio in follow mode (audio and video have the same tie

configuration), select the Follow box at the bottom of the window. To set up audio in breakaway mode (audio and video have different tie configurations), deselect the Follow box.

•To make the control program easier to use, assign a device icon to each input and output. Click on a box that represents an input or output, and drag the desired icon onto the box from the icon palette that appears.

•To create a tie, drag an input box to one or more output boxes. To remove a tie, drag the output box to its tied input box or to the trash can.

•For quick display of information on a specific input or output device, position the cursor over that device in the control program window. The program opens a window that details the connections to that device, the audio level, the RGB delay, and the frequency of the video signal input from or output to that device. See the inset box in figure 5-3.

Updating firmware

The firmware upgrade utility provides a way to replace the firmware that is coded on the switcher’s control board without taking the switcher out of service and replacing the firmware IC chip.

Update the switcher firmware as follows:

1.	Visit the Extron web site, www.extron.com, select the CrossPoint/MAV Plus
	product category, and select the latest firmware install package (*.exe file) for
	download. Note the folder to which you save the firmware file.
2.	Run the executable (*.exe) file to decompress the firmware file.
3.	Start the Matrix Switcher Control Program and connect to the MVX 128 A
	switcher. See Using the software in this chapter, steps 1 through 4, starting on
	page 5-3.
4.	Click Tools > Update firmware. The open file window appears (figure 5-4).
