10 AVX-400 Enova Twisted Pair Presentation Switcher Operation/Reference Guide
Configuration Port (PROG)
The AVX-400 contains one low-speed type-B USB connection located on the front of the unit. Use a standard USB cable
to establish a connection between the device and your PC's USB port. This connection enables you to program the
switcher by using AMX DCS software. See the
AMX DCS Software section on page 17 for more information.
Power Connector
The AVX-400 uses a 12 VDC-compliant power supply to provide power to the switcher through the front 2-pin 3.5 mm
mini-Phoenix power connector. Use the power requirements information described in the product’s Specifications table
to determine the power draw. The incoming PWR and GND cable from the power supply must be connected to the
corresponding locations within the power connector.
The current draw for the AVX-400 with no input plates is 750mA. The following table lists the current draw for each
type of input wallplate you can connect to the AVX-400.
You can use this information to determine the overall current draw of the AVX-400 and its components. To illustrate, an
AVX-400 with 2 VGA wallplates, 1 Component wallplate, and 1 Composite wallplate draws:
750 + 140 + 140 + 160 + 110 = 1.3A
FIG. 15 Configuration port
FIG. 16 Power connector
Wallplate Current Draw
Component 160mA
VGA 140mA
Composite 110mA
HDMI 98mA
The above equation does not take into account an audio source, which can increase
the draw by up to 1A depending on frequency and volume.
This unit should only have one source of incoming power.
Using more than one source of power to the Controller can result in damage to the
internal components and a possible burn out.
Apply power to the unit only after installation is complete.
