Uploading firmware to the MPS via an SIS command
There are two ways to upload firmware to the switcher:
• Use the MPS Control Program
• Use SIS commands entered via a communication utility such as HyperTerminal.
Extron recommends that you use the MPS control Program to upload firmware (See
Uploading Firmware Updates on page 4-3) and reserve this SIS procedure for
correcting firmware that has been corrupted and is unable to respond to the MPS
Control Program.
To load firmware using SIS commands, follow this procedure:
1. Obtain the new, correct firmware file.
a. Visit the Extron Web site, www.extron.com and locate and select the
product page for the MPS 112 or MPS 112CS.
b. In the MPS product page, locate the most recent firmware file, release
notes, and firmware update instructions. Save these files on your
computer’s hard drive, and note the file path of the folder where the files
have been saved.
2. Open a communications utility program such as HyperTerminal and select the
COM port that is connected to the switcher’s RS-232 port. Protocol for
communication with the MPS switcher is as follows:
• 9600 baud
• 8 data bits
• 1 stop bit
• no parity (none)
• no flow control (none)
The firmware upload process 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: Click File >
Properties > Settings> ASCII Setup, make sure that the echo feature is
turned on (checked, as shown below), then click OK twice.
