The Program port uses a standard Type-A-to-Type-B USB cable to connect to a PC. When connected, you
can view your DVX among the listed Masters connected via USB in NetLinx Studio. See the Initial
Configuration chapter in the NX-Series Controllers WebConsole and Programming Guide for more
information.
USB Port
The front panel of all models features one Type-A USB port you can use to connect a mass storage device
for loading .tkn files, reading or writing configuration files and log files, or updating the firmware on the
unit.
NOTE:
This USB port only supports a FAT32 file system.
This USB port uses standard USB cabling to connect to any mass storage or peripheral devices.
NOTE:
USB hubs are not supported on this port.
Rear Panel Audio Inputs and Audio Outputs
The following sub-sections describe each component on the rear panel of the DVX. Refer to FIG. 2 & 3 on
“
” section for the component layout of the rear panel.
AUDIO INPUTs
The AUDIO INPUTs connectors are 3.5 mm 5-position captive-wire terminals that can be wired for either
balanced (differential) or unbalanced (single-ended) stereo audio. Since the DVX allows independent
switching of video and audio, video and audio inputs of the same number do not have to be connected to
the same source equipment. These connectors feature the following specifications:
Nominal input level: +4 dBu (1.228 Vrms) or -10 dBu (0.3262 Vrms) unbalanced
Maximum input level: 2 Vrms
Input impedance: >12k ohms unbalanced, >12k ohms balanced, DC coupled
Source devices require either balanced (differential) or unbalanced (single-ended) connections. The
following picture illustrates options for wiring between sources and input connectors. More than one
option can be used in the same system.
