Enova DVX-2100HD 6x2 All-in-One Presentation Switcher Operation/Reference Guide
PROGRAM Port (Type-B USB)
The PROGRAM port is a Type-B USB connector that connects the DVX-2100HD to a USB port on a PC, and
is intended primarily to be used to configure system settings (FIG. 21).
Be sure that your PC's COM port and terminal program's communication settings match those in the table
below:
Preparing the DVX-2100HD for Serial Communication
1.
Before using the USB port on the DVX-2100HD you must install the appropriate FTDI driver. A link to
this driver can be found on the Product web page at www.amx.com.
2.
Connect your PC's USB port to the USB Configuration Port on the DVX-21010HD. Either allow
Windows to install the driver automatically (internet connection required), or point the installer to the
location where you have previously saved the driver. This will create a new virtual COM port on your PC.
3.
Edit the Serial Communication settings in NetLinx Studio to use the virtual COM port created in step 2,
and set the communication parameters to 115.2K baud, N, 8, 1.
ID Pushbutton
The ID pushbutton (FIG. 22) sets the NetLinx ID assignments of the Internal Control Device. It has no effect
on the Internal Switcher Device.
Think of the PRD Mode (On) equating to a PC’s SAFE Mode setting. This mode
allows a user 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/deactivating this mode on the
Configuration Port DIP switch #1.

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