Extron electronic MVX 88 Series manual Loading firmware using an SIS command, Preliminary

Loading firmware using an SIS command

NFirmware can be uploaded two ways:

1. Using the Matrix Switchers Control Program.

2. Using the Eupload SIS command entered via a communications utility such as HyperTerminal.

Extron recommends that you upload firmware using the Matrix Switchers Control Program (see “Updating the firmware” on page 4-16) and reserve this SIS procedure for correcting firmware that has been corrupted and unable to respond to the Matrix Switchers Control Program.

Firmware can be loaded using SIS commands as follows:

1.	Visit the Extron web site, www.extron.com, select the MVX switcher product
	category, select the latest firmware file for download, and copy it to your
	computer. Note the folder to which you save the firmware file.
2.	Start a communications utility such as HyperTerminal. Select the Comm port
	that is connected to the switcher’s RS-232 port. Use 9600 bits per second, 8
	data bits, “none” parity, 1 stop bit, and “none” flow control.

NIf you are performing this procedure to recover from corrupted firmware, the switcher will respond only to the “n”, “q”, and “Eupload” SIS commands.

NThe firmware upload can take several minutes. If HyperTerminal’s echo function is turned off, you will have no indication that the upload is progressing. If desired, turn on the echo function as follows (figure 4-3): Click File >

Properties > Settings > ASCII Setup..., check the Echo typed characters locally checkbox, and then click Ok twice.

3.	Depress the keyboard’s Esc key and then type upload. The computer
	responds with the “Go” prompt.
4.	Click Transfer > Send text file... .
5.	Click the Files of type: drop box and select All files (*.*).
