Loading firmware using an SIS command
Firmware can be uploaded two ways:
1 . Using the Universal Switcher Control Program.
2 . Using the Esc upload SIS command entered via a
communications utility such as HyperTerminal.
Extron recommends that you upload firmware
using the Universal Switcher Control Program (see
Updating the firmware on page 3-12) and reserve
this SIS procedure for correcting firmware that has
been corrupted and is unable to respond to the
Universal Switcher Control Program.
Firmware can be loaded using SIS commands as follows:
1 . Visit the Extron Web site, www.extron.com, select the
MMX 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.
If you are performing this procedure to recover from
corrupted firmware, the switcher responds only to the
“n”, “q”, and “
Esc upload” SIS commands.
