Chapter 3: Updating Flash Memory
The printer’s firmware (Microcom Corporation Application; MCA) or Bootloader (Microcom
Corporation Bootloader; MCB), which is stored in the flash memory, may be updated using
the different methods. The procedures are slightly different depending on the type of
update required. This section provides the information necessary to properly update the
firmware stored in flash memory.
Both the MCA and MCB code files should always be sent to the printer in the compressed
zipped format. The MCB or Bootloader should be updated after the MCA has been updated
to avoid any compatibility conflicts.
3.1 Compressed File Update
This method is used to update the firmware stored in flash memory.
To update the printer’s
firmware the following are required: a compressed MCA or MCB (ZIP file), a host computer
equipped with a RS-232 serial port, and a Terminal Emulation Program (i.e., HyperAccess,
HyperTerminal, Procomm Plus, Tera Term Pro...). The printer is configured at the factory
with serial parameters of 9600,n, 8,1 and the terminal emulation program will need to be set
accordingly.
It is a good idea to completely read through the procedure before an update attempt is
made.
Do not send any unnecessary characters or remove the printer’s power during the
update or the printer may become inoperable. Refer to section 3.2 in the event the printer
does not function properly after an update and the printer has become inoperable.
1. Make sure the RS-232 serial connection is made between the host and the printer
including the proper Baud rate.
2. It is recommended to use the fastest Baud rate up to 115200 to reduce transfer time.
Refer to the
“^D670)” command regarding the printer’s serial port parameters. If the
printer does not update properly, use a slower Baud rate to transfer the update.
3. Contact the Microcom Corporation support department and/or visit the following web
address www.microcomcorp.com to acquire the desired MCA file.
4.
Issue the “^D945)?” command and retain the resulting listing for comparison after
flash update.
5. Send the MCA or MCB file to the printer in compressed form (ZIP). The MCA must
be updated before the MCB if both are being updated. Failure to do this may cause
the printer to become unstable.
6. Send the MCA file to the printer in compressed form (ZIP).
7. After the printer has identified the MCA file, the following dialog will be reported to the
host: “ File received. Unzipping. Please Wait… ” This dialog is only reported if the printer is
set to use the VERBOSE response set. Refer to the “^D550)” command for
additional information regarding the printer response sets.
