Serial (RS-232) Upgrade
1. Press Menu. Select System, then select Upgrade.
2. Use the arrow keys to choose Yes to begin upgrading the printer software,
or No to cancel. The printer will reset, and the display will read Waiting for
serial data...
3. If you have not already done so, connect the male end of the serial cable to
the printer’s utility I/O port. Connect the female end of the cable to the
desired COM port on the host computer. The serial cable must be straight-
through (no lines are swapped).
4. Insert the upgrade diskette into the disk drive. To run the upgrade program,
type the word upgrade followed by the COM port that is being used and the
baud rate. The baud rate should be set to either 9600 or 19.2 k, and the
handshake method should be set to Hardware. Use all lowercase letters to
run the upgrade program. For example, if COM1 is being used at 19200,
type: upgrade com1 19200
5. The computer will begin copying files to the printer, and the printer’s Data
LED will flash. The printer will display the file that it is receiving and the
percentage received. When data transmission is finished, the printer will
erase, then re-program its flash memory, and reset itself. The printer is now
ready for use.
NOTE
IF YOU ARE NOT RUNNING WINDOWS 95, A BAUD RATE OF
19.2K IS ONLY SUPPORTED IN VERSIONS OF DOS 6.2 AND
HIGHER. IF YOU ARE USING A LOWER VERSION OF DOS, A
BAUD RATE OF 9600 MUST BE USED.
