1.1.4 DIMM (GO49/G054)
The DIMM ROM, used for downloading controller firmware, is not supported by the
G049/G054. There are 2 ways to upgrade the controller firmware:
1. Using the IC card (flash card).
2. Using a PC (via parallel port)
1.1.5 RELEASING NEW CONTROLLER FIRMWARE
Two controller firmware files will be released (e.g. P3card.rom and P4card.rom).
This firmware can be copied to an IC card using the Swapbox utility.
To download firmware from a PC to the printer, a byte-swapping operation must be
performed on the released firmware. To do this, use the Byte Swap button of the
SSU (Stinger Service Utility) program. This creates new files, e.g., P3carddwn.rom
and P4carddwn.rom.
To summarize:
•
To use the Swapbox utility: Use the released firmware file (*card.rom)
•
To copy to an IC card or DIMM plugged into the printer (from a PC through a
parallel cable): Use the byte-swapped file (*carddwn.rom - created by SSU byte
swap)
•
To copy directly to the printer’s firmware flash ROM (from a PC through a parallel
cable): Use the byte-swapped file (*carddwn.rom - created by SSU byte swap)
