If a coax host Is not available and basic setup selections need to be changed, the interface has the option of a push button setup as defined in Appendix B. This option enables the basic interface features and RPQ options to be selected.

RESTORING FACTORY DEFAULT CONFIGURATION

The factory default configuration selections can be restored to the NV memory of the interface by either sending a Host Download Command ‘98,0’or by turning on the printer when the coax cable is disconnected and performing the following steps (waft for printer to be READY):
