Appendix
B
Upgrading the Firmware
Periodically, EndRun Technologies will make bug fixes and enhancements to our products available
for download from our website. All such downloads are freely available to our customers, without
charge. After you have downloaded the appropriate FLASH binary image file from the EndRun Tech-
nologies website, you are ready to perform the upgrade to your distribution chassis.
This appendix contains instructions for upgrading via the RS-232 serial port. See Appendix C - Net-
work Port Option for instructions on upgrading via the network port.
What You Need To
Perform the Upgrade
You will a terminal program which supports file uploading using protocols XMODEM 128 with CRC
or XMODEM 1K with CRC. These are very common file transfer protocols and should be supported
by virtually any terminal program.
CAUTION
You may perform the upload using any of the support serial I/O parameter combinations, except that 8 data
bits must be used
. You must use 8 data bits because the FLASH image that you will be uploading is in a
binary format.
Performing
the Upgrade
Configure your terminal program and the distribution chassis to communicate at the desired baud rate
by using the settings facility for your terminal program and the
port
command for the distribution
chassis. Refer to
Section 3 - Control and Status Commands
for details on using the
port
command.
CAUTION
Make sure only one port (serial or network) is active during the upgrade procedure. In other words, if us-
ing the serial port to upgrade, make sure there is no activity on the network port (if any).
