Loading Firmware Using an SIS Command

NOTE: Firmware 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 49) 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.Obtain the latest firmware file for the matrix switcher (see steps 1 through 6 of “Updating the firmware” on page 49.

2.Start a communications utility such as HyperTerminal. Select the Comm port that is connected to the RS-232 port of the switcher. Use 9600 bits per second, 8 data bits,

“none” parity, 1 stop bit, and “none” flow control.

NOTES: • If you are performing this procedure to recover from corrupted firmware,

the switcher will respond only to the “n”, “q”, and “Eupload” SIS

commands.

• The firmware upload can take several minutes. If the echo function of HyperTerminal is turned off, you will have no indication that the upload is progressing. If desired, turn on the echo function as follows (see figure 22): Click File > Properties > Settings > ASCII Setup..., check the Echo typed characters locally checkbox, and then click Ok twice.
