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. 42).
The following table shows the rear panel Program Port connector (male), pinouts, and signals.
Consider equating PRD Mode to a PC’s SAFE Mode setting. With PRD mode, you
can continue to power a unit, update the firmware, and download a new program
while circumventing any problems with a currently downloaded program. You must
power cycle the unit after activating/deactivating PRD mode on Program 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.
