PROGRAM Port
The PROGRAM port is a DB-9 male RS-232 port that connects the DVX to a communication port on a PC,
and is intended primarily to be used to configure system settings (FIG. 41).
The following table shows the rear panel Program Port connector (male), pinouts, and signals.
Think of the PRD Mode (On) equating to a PC’s SAFE Mode setting. This mode
allows you to continue powering a unit, update the firmware, and download a new
program while circumventing any problems with a currently downloaded program.
Power must be cycled to the unit after activating or deactivating this mode on the
Configuration Port DIP switch #1.

The PROGRAM port is not recommended for firmware updates or large file transfers.
Any large data-intensive operations are better handled via LAN.
