PAL Application Bootstrap Bypass

Hold down the CANCEL button while turning on power. Do not release until the printer displays the Interface Status Online message.

The printer supports the downloading of standalone or other user PAL applications into a reserved portion of the internal flash ROM. Given the proper identifier at the start of such an application, the PAL interpreter will automatically start executing any such application once the firmware has completed initialization.

This presents a problem when recording certain types of PAL applications into the printer. Many types of PAL applications are designed to assume control of the printer’s RS-232 interface at power-on in order to accept non- PAL commands and/or data from the host system. With a PAL application in control of the RS-232 interface, the host system is unable to communicate directly with the PAL interpreter. As a result, the operator cannot send the PAL commands necessary to erase and/or replace the PAL application program contained in the flash ROM.

The PAL application bootstrap bypass feature allows the operator to stop the PAL interpreter from automatically executing any PAL application contained in the flash ROM. Thereby instructing the interpreter to enter normal PAL interpretation mode and allowing the operator to send the necessary commands to erase and/or replace any PAL application program contained in the flash.

To clear ROM memory area send the following command to the printer after performing the above “Bootstrap”:

(A:) () _deviceformat

Turn the printer off and then on. It should come up in the On-Line mode. You are now ready to load the new application.

Release Identification Message Pause

ONLINE

Press and release the PAUSE button while the firmware is displaying any release identification message (“RelID”). The firmware will pause and leave the

ENTER

message on the display until the PRINT button is pressed.

As explained above, this feature provides the operator with sufficient time to record the release identifiers in order to report them to technical service personnel.
