Chapter 2 Loading Function Code To Flash Memory In The Printer
Loading Function Code To Flash Memory In The Printer
This section contains two loading techniques:
• How to load function code through the parallel or serial port of the printer.
• How to load function code through the Ethernet port using the file transfer
protocol (ftp).
Loading Code Through The Parallel Or Serial Port
1. Installing new function code erases all saved printer configurations. Make
a printout of
all
saved configurations. You will use the printouts to restore
printer configuration.
2. Set the printer power switch to O (off).
3. If the printer is already connected to the serial or parallel port of a
computer running PC-DOS or MS-DOS, go to step 9. If not, go to step 4.
4. Disconnect all data input cables from the printer interface.
5. Connect a parallel data cable to the LPT1 port (or a serial data cable to
the COM1 port) of an IBM-compatible computer that is using the PC-DOS
or MS-DOS operating system. The computer must contain the function
code to be downloaded. You can connect the cable to the LPT2 port if the
LPT1 is already in use.
6. Connect the data cable to the appropriate I/O port of the printer.
7. Power on the computer.
8. Check that the function code file is on the computer by listing the contents
of the directory where the function code is located. Change (CD) to the
directory that contains the function code file.
9. On the printer control panel, press and hold down the ON LINE + FF
keys. Without releasing the keys, power the printer on. Continue holding
the ON LINE + FF keys down for five seconds, then release them. Wait
until you see “WAITING FOR PROGRAM DOWNLOAD” on the LCD.
10. If you are downloading via the parallel port go to step 13; otherwise, press
the
< (NEXT) key; “SELECT DOWNLOAD PORT=DATAPRODUCT”
appears on the LCD.
11. Press
< (NEXT) again to cycle through the download ports available in
the printer:
DATAPRODUCT (parallel)
CENTRONICS* (parallel) (default port)
RS232-9600 (RS-232 serial, 9600 baud. This is the only rate older
versions of DOS can use.)
RS232-19.2K (RS-232 serial, 19200 baud)
Note If Ethernet is installed, you must install the code through the Ethernet port
using ftp.
