This guide provides instructions for upgrading the firmware of a PDL (Programmable Data Link) device. To upgrade the firmware, users must first download the PDL/EDL operating firmware into the same directory as PDLCONF/EDLCONF. It is recommended to download the zipped version of the firmware to avoid any issues with the browser. After connecting the PDL device to the computer, users must run PDLCONF/EDLCONF and select the "Upgrade modem firmware" option from the top left corner of the screen.
Instructions for upgrading PDL firmware (also available on page 14 of the PDLCONF User Guide):
- Download the PDL/EDL operating firmware into the directory where PDLCONF/EDLCONF is located. Note that some browsers may not properly download the firmware file. We recommend that you download the zipped version to avoid this problem.
- Connect your PDL to your computer using the programming cable and run PDLCONF/EDLCONF.
- After loading the configuration, click on the icon in the upper left-hand corner of the screen, and select "Upgrade modem firmware."
