You can upgrade the operational firmware in the Matrix E1 without physically opening the device 
or being in the same location. The software storage sector in the flash memory of the device is 
reprogrammed, allowing you to easily download firmware feature enhancements and problem fixes 
to the device from a local or remote location.

Firmware can be downloaded to the device in two ways: 

Via TFTP download. This is the recommended firmware upgrade method. It uses a TFTP server 
connected to the network and downloads the firmware using the TFTP protocol. A TFTP 
download is much faster than a serial download, requiring only a few seconds, and can be used 
to upgrade a device that is not physically in the area. For details, refer to 

.

Via the serial (console) port. This procedure is an out-of-band operation that copies the firmware 
through the serial port to the device. This operation takes approximately three minutes and 
requires minimal configuration. Serial console download has been successfully tested with the 
following applications: 

SecureCRT Version 3.3.2, 

HyperTerminal Copyright 1999

Any other terminal applications may work but are not explicitly supported. For details, refer

A serial download is the easiest method to upgrade the device firmware, requiring the least amount 
of equipment and configuration.

To download device firmware via the serial (console) port, proceed as follows:

1. With the console port connected, reset the device by powering the device off and then on.

2. As the device is booting up, a message displays indicating POST Version, followed by “Starting 

application”. At this point, reset the device again.

3. When the Power On Self Test (POST) begins, press ESC to bypass it. The following message 

displays: 

4. Press D to download system firmware. The following message displays:
