The programs (firmware) that run in the SEL-2711 are stored in Flash memory. New programs
can be stored to the SEL-2711 via a file transfer to the SEL-2030. To load the new version of the
SEL-2711, follow the instructions below. The SEL-2711 and SEL-2030 each have two programs
that may need to be upgraded: the regular, or “executable” program, and the “SEL
BOOT
” program.
See
Appendix A: Firmware Versions
to find out what programs you should upgrade to make the
latest version of the SEL-2711 function optimally.
SEL-2711/SEL-2030 Firmware Upgrade Instructions
1.
Establish a serial connection with the front panel port on the SEL-2030. Make sure your
communications software is capable of performing XMODEM file transfers. If it is not, then
switch to software that has this capability.
2.
Use the ACCESS and 2ACCESS commands to gain Level 2 Access to the SEL-2030.
3.
Enter the command “L_D” and then verify by responding “Yes” to the verification prompt.
This places the SEL-2030 in SEL
BOOT
mode where it is ready to receive new program code
for itself or a connected Protocol Card. While in SEL
BOOT
mode, you can enter the “HELP”
command to receive a description of the available commands.
4.
Use the “BAU ” command to set the port baud rate as high as possible (38400 maximum).
To set the port at 38400, enter “BAU 38400”. Change the baud rate parameter in your
communications software to match and then re-establish communications.
5.
If you are upgrading the SEL-2711:
Type the command “REC n”, where n is the SEL-2711 protocol card port (e.g. if the card is
on port 17, then enter “REC 17”). Respond “Y” to the confirmation prompt. Once the
SEL-2030 is ready to receive the new code, it will display another prompt indicating that you
may press any key to initiate the firmware download. Press a key and then send the new
SEL-2711 code using an XMODEM file transfer.
If you are upgrading the SEL-2030:
Type the command “REC ”. Respond “Y” to the confirmation prompt. Once the SEL-2030
is ready to receive the new code, it will display another prompt indicating that you may press
any key to initiate the firmware download. Press a key and then send the new SEL-2030 code
using an XMODEM file transfer.
If you are upgrading the SEL-2711 SEL
BOOT
code:
Type the command “REC boot n”, where n is the SEL-2711 protocol card port (e.g. if the
card is on port 17, then enter “REC boot 17”). Respond “Y” to the confirmation prompt.
Once the SEL-2030 is ready to receive the new code, it will display another prompt indicating
