Firmware Upgrade Instructions
Introduction
SEL occasionally offers firmware upgrades to improve the performance of your
transceiver. The SEL-3022 stores firmware in Flash memory; therefore, changing
physical components is not necessary. These instructions give a step-by-step procedure
to upgrade the SEL-3022 firmware by uploading a file from a personal computer to the
transceiver via the DCE serial port.
Required Equipment
You will need the following to perform a firmware upgrade:
Personal computer (PC)
SEL-5809 Settings Software
Terminal emulation software that supports the Xmodem 1K protocol
(these instructions use HyperTerminal
®
from a Microsoft
®
Windows
®
operating system)
SEL-C388 Serial Cable or equivalent DCE to DTE “straight-through”
cable capable of supporting hardware flow control
The firmware upgrade file received from your SEL customer service
representative
Upgrade Procedure
Perform the following steps to upgrade the SEL-3022 firmware:
Step 1. Record all settings if they are to be used after the upgrade. Typically,
the previous session saves all but the cryptographic keys from the
previous connection session. Right-clicking on the device will allow
you to view the previous device image settings.
Step 2. If the SEL-3022 is in service, disconnect the cable connected to the
DCE serial port.
