Attach the parallel converter to the end of the parallel cable. This will make the cable symmetrical on both ends.
Connect the cable to the computer and the parallel 1 port on the external adapter. On the Pro 3/X2030 adapters, this is the port closest to the network cable.
Press and hold the Test and Menu buttons until all lights come on.
While still holding the Test button, release the Menu button. The adapter will begin to either alternate between the Menu and Parallel 1 on the single port adapters, or sweep right, skipping the Parallel 2, on the Pro 3/x2030.
When the Parallel 1 light is on, release the Test button. The adapter should then start a "sweep right" pattern, indicating that it is waiting for a flash file over Parallel 1.
Open a command prompt on the computer and and change to the directory that contains the firmware file.
From the command prompt, copy the file to the parallel port using the following commands:copy filename lpt1 /b where is the firmware file for the adapter. The Menu light on the adapter should flash, and then go solid.
The adapter should then reset itself and either go back to a ready state or to a "no network connection" pattern of lights.
Print a test page from the adapter to verify that the new code has been processed.
Attach the parallel converter to the end of the parallel cable. This will make the cable symmetrical on both ends.
Connect the cable to the computer and the parallel 1 port on the XLe adapter.
On the adapter, press the Reset button. The adapter will begin its normal startup procedure.
While the adapter is starting up, hold down the Test button until the Data light flashes, indicating that the adapter is ready to receive a flash file.
Open a command prompt and change to the directory that contains the firmware file.
Copy the file to the XLe using the following command:copy /b filename.unc lpt1 where is the appropriate firmware file.
While the firmware is downloading and processing, the Test and Data lights will blink, and the power light will stay on. The Status light will also start blinking while the adapter is actually flashing the code. If the Status, Test, and Data lights go out, an error has occurred. Verify the parallel cable connection and repeat this procedure. When the flash file has been downloaded successfully, the Test light will go out and the Status and Data lights will alternate rapidly.
Remove the parallel cable and set the adapter up again with its network connection. Print out a test page to verify that the flash file has been sent correctly.
