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).

Note

If Ethernet is installed, you must install the code through the Ethernet port

 

using 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)
