Quick Start

The Crestron® DM-NVX-352C network AV encoder/decoder card transports ultra high-definition 

4K60 4:4:4 HDR video over standard Gigabit Ethernet. Engineered to function as either an 

encoder or decoder, the DM-NVX-352C features secure web-based control and management,  

two auto-switching HDMI® inputs and one HDMI output, an analog audio input or output, USB 

and KVM integration, video wall processing, and support for copper and fiber LAN connectivity. 

The DM-NVX-352C also supports Dante® audio networking and AES67.

Install the Card

The DM-NVX-352C is designed to occupy the DMF-CI-8 chassis.

CAUTIONS:

• 

DM NVX™ cards are susceptible to damage from electrostatic discharge (ESD).  

Observe standard ESD precautions when handling the cards. Wear an ESD wrist strap 

that is connected to ground, and place the cards on grounded surfaces only.

• 

To prevent damage to a card that is connected to cables, disconnect all cables from the 

card before installing the card into a card slot or removing the card.

 

NOTES:

• 

In a new installation of the DMF-CI-8, it is recommended that the cards be installed before 

power is applied to the chassis. In an existing installation of the DMF-CI-8, the cards can 

be added or replaced without the need to shut down the chassis—the cards are  

hot swappable. 

• 

When installing the cards into a partially populated DMF-CI-8, install the cards into slots 

5–8 before using slots 1–4. Doing so ensures better cooling and lower power consumption. 

In addition, always cover empty slots using the filler plates included with the chassis.

 

To install a card into the DMF-CI-8:

1. 

Using a #2 Phillips screwdriver (not included) or your fingers, remove the filler plate of an 

unused slot by loosening the two captive panel screws.

2. 

Carefully insert the card into the card guides of the selected slot, and then push the card 

inward until it engages the chassis backplane.

3. 

Finger-tighten the two captive panel screws to secure the card—do not overtighten  

the screws.

Connect the Card

Connect the card as required for the application.

NOTES:

• 

The DM-NVX-352C can be configured to use either the DEVICE port or the HOST port.  

Both ports cannot be used simultaneously.

• 

The DM-NVX-352C provides two LAN ( ) ports. LAN port 1 is a 10BASE-T/100BASE-TX/ 

1000BASE-T port. LAN port 2 is an SFP port that connects to a fiber-optic network using 

the appropriate SFP-1G transceiver module. (Refer to the SFP-1G Series Installation Guide 

[Doc. 7979] for information about installing Crestron SFP-1G Series transceiver modules.) 
Only one LAN port at a time can be used as the primary LAN connection to stream 

network video, allowing the other port to be used for connection to a local network device 

or to another DM NVX device. When a LAN port is used as the primary LAN connection, 

the port must connect to a 1000BASE-T switch in order to stream network video.
