Sending Firmware via Serial
Downloading firmware using serial RS-232 is not recommended due to the
size of the firmware and significant wait time required to complete the
process. Downloading through serial requires firmware in the form
FILENAME.prg only.
1. Copy the firmware to the printer by issuing these commands at the
Command prompt:
mode COM1:9600,N,8,1,P
copy /b FILENAME.prg com1
where FILENAME.prg is the target firmware.
NOTE: Some systems can only use the 9600 baud rate. The baud rate
information entered in the above commands must match the Baud
Rate setting saved in the Power-Up Config.
IMPORTANT DO NOT interrupt the downloading process once it has started.
Interrupting a download will leave the flash memory on the controller
PCBA and NIC incompletely loaded, and the printer may not boot up.
2. The process is complete when the new software has successfully loaded
into flash memory and the printer has reset itself.
